+Subject: alfred: vis: Use rtnl to query list of hardifs of meshif
+
+The normal way of network related programs to query the state of interfaces
+is to use the rtnetlink. Most of these data can also be queried via sysfs
+but it is better to use the same way for both retrieving the list of
+interfaces and modifying the list of interfaces.
+
+Also the sysfs files are deprecated and cause warnings when access:
+
+  batman_adv: [Deprecated]: batadv-vis (pid 832) Use of sysfs file "mesh_iface".
+  Use batadv genl family instead
+
+In worst case, the file doesn't even exist when batman-adv was compiled
+without sysfs support.

+Subject: alfred: vis: Retrieve hardif status via generic netlink
+
+The batman-adv kernel module can now be compiled without support for sysfs.
+But the batadv-vis interface retriever can only get the status via the per
+hardif sysfs file iface_status. To still have some information, use
+BATADV_CMD_GET_HARDIF to retrieve the status and fall back to sysfs when
+the status could not retrieved via generic netlink.
+
+This also solved the warning about deprecated sysfs file access
+
+  batman_adv: [Deprecated]: batadv-vis (pid 1365) Use of sysfs file "iface_status".
+  Use batadv genl family instead

+Subject: alfred: Allow exactly one interface for secondary mode
+
+A primary alfred daemon allows syncing over more than one interface. But
+the secondary alfred daemon needs exactly one interface. But the check for
+this property was insufficient because it allowed paramters like
+"-i wlan0,asd" when wlan0 is valid and asd is not valid.
+
+The better solution is to really use the number of interfaces given to
+alfred instead of the number of interfaces evaluated as "valid".

+Subject: alfred: Allow start of server without valid interface
+
+The alfred server always needs interfaces to operate on. But these
+interfaces might not exist at the moment when the daemon process is
+started. This caused an error and stopped the process.
+
+But alfred is able to deal with interfaces which disappeared at runtime but
+existed at startup. To force a similar behavior for the alfred startup, the
+parameter "--force" or "-f" is introduced.

+Subject: batctl: Make vlan setting explicit
+
+The requirement to have a VLAN master device on top of the batadv mesh
+interface is artificially limiting the capabilities of batctl. Not all
+master devices in linux which register a VLAN are from type "vlan" and are
+only registering a single VLAN.
+
+For example VLAN aware bridges can create multiple VLANs. These require
+that the VLAN is identified using the VID and not the vlan device.

+Subject: batctl: Integrate hardif setting framework
+
+batctl currently supports settings which are either mesh interface or vlan
+specific. But B.A.T.M.A.N. V introduced two additional settings which are
+hard (slave) interface specific.
+
+To support these, an additional command prefix called hardif is implemented
+for some sysfs commands:

+Subject: batctl: Prefer netlink hardif status retrieval over sysfs
+
+The sysfs code in batman-adv was changed to print a deprecated warning when
+sysfs files are accessed. The `batctl if` call would therefore cause
+warnings like this in the kernel log:
+
+  batman_adv: [Deprecated]: batctl (pid 18540) Use of sysfs file "iface_status".
+  Use batadv genl family instead
+
+It is now appropriate to try the generic netlink BATADV_CMD_GET_HARDIF
+request first to get the status of the interface before falling back to
+sysfs.

+
+A deletion of a hardif from a batadv meshif will also get a success reply
+from the kernel when the hardif was never part of the batadv meshif. If the
+batadv meshif had no attached hardifs before the removal was started, then
+users are then not expecting that the batadv meshif is removed at all.
+
+Since the delete operation is not an atomic compare-and-swap operation,
+just check first the number of attached interfaces and only start the
+removal of the batadv meshif when the number attached hardifs was reduced.

-
-The original patch requires Linux 5.16.0 or a mac80211 compat header with this

-OpenWrt main is still using older Linux kernel versions for some targets.

-OpenWrt main is still using older Linux kernel versions for some targets.
-
-This reverts commit f0fb49c5ab70dfa064f0aa8d1c5d84f65e8cbc86.

+Subject: batman-adv: Fix duplicated OGMs on NETDEV_UP
+
+The state of slave interfaces are handled differently depending on whether
+the interface is up or not. All active interfaces (IFF_UP) will transmit
+OGMs. But for B.A.T.M.A.N. IV, also non-active interfaces are scheduling
+(low TTL) OGMs on active interfaces. The code which setups and schedules
+the OGMs must therefore already be called when the interfaces gets added as
+slave interface and the transmit function must then check whether it has to
+send out the OGM or not on the specific slave interface.
+
+But the commit 0d8468553c3c ("batman-adv: remove ogm_emit and ogm_schedule
+API calls") moved the setup code from the enable function to the activate
+function. The latter is called either when the added slave was already up
+when batadv_hardif_enable_interface processed the new interface or when a
+NETDEV_UP event was received for this slave interfac. As result, each
+NETDEV_UP would schedule a new OGM worker for the interface and thus OGMs
+would be send a lot more than expected.

+Subject: batman-adv: Avoid free/alloc race when handling OGM2 buffer
+
+A B.A.T.M.A.N. V virtual interface has an OGM2 packet buffer which is
+initialized using data from the RTNL lock protected netdevice notifier and
+other rtnetlink related hooks. It is sent regularly via various slave
+interfaces of the batadv virtual interface and in this process also
+modified (realloced) to integrate additional state information via TVLV
+containers.
+
+It must be avoided that the worker item is executed without a common lock
+with the netdevice notifier/rtnetlink helpers. Otherwise it can either
+happen that half modified data is sent out or the functions modifying the
+OGM2 buffer try to access already freed memory regions.

+Subject: batman-adv: Avoid free/alloc race when handling OGM buffer
+
+Each slave interface of an B.A.T.M.A.N. IV virtual interface has an OGM
+packet buffer which is initialized using data from the RTNL lock protected
+netdevice notifier and other rtnetlink related hooks. It is sent regularly
+via various slave interfaces of the batadv virtual interface and in this
+process also modified (realloced) to integrate additional state information
+via TVLV containers.
+
+It must be avoided that the worker item is executed without a common lock
+with the netdevice notifier/rtnetlink helpers. Otherwise it can either
+happen that half modified/freed data is sent out or functions modifying the
+OGM buffer try to access already freed memory regions.

+Subject: batman-adv: Avoid OGM workqueue synchronous cancel deadlock
+
+batadv_forw_packet_list_free can be called when an interface is being
+disabled. Under this circumstance, the rntl_lock will be held and while it
+calls cancel_delayed_work_sync.
+
+cancel_delayed_work_sync will stop the execution of the current context
+when the work item is currently processed. It can now happen that the
+cancel_delayed_work_sync was called when rtnl_lock was already called in
+batadv_iv_send_outstanding_bat_ogm_packet or when it was in the process of
+calling it. In this case, batadv_iv_send_outstanding_bat_ogm_packet waits
+for the lock and cancel_delayed_work_sync (which holds the rtnl_lock) is
+waiting for batadv_iv_send_outstanding_bat_ogm_packet to finish.
+
+This can only be avoided by not using (conflicting) blocking locks while
+cancel_delayed_work_sync is called. It also has the benefit that the
+ogm scheduling functionality can avoid unnecessary delays which can be
+introduced by a global lock.

+Subject: batman-adv: Fix DAT candidate selection on little endian systems
+
+The distributed arp table is using a DHT to store and retrieve MAC address
+information for an IP address. This is done using unicast messages to
+selected peers. The potential peers are looked up using the IP address and
+the VID.
+
+While the IP address is always stored in big endian byte order, it is not
+the case of the VID. It can (depending on the host system) either be big
+endian or little endian. The host must therefore always convert it to big
+endian to ensure that all devices calculate the same peers for the same
+lookup data.

+A transmission scheduling for an interface which is currently dropped by

+Instead it has to stop submitting the OGM when it detect that the buffer

+Subject: batman-adv: fix batadv_nc_random_weight_tq
+
+and change to pseudorandom numbers, as this is a traffic dithering
+operation that doesn't need crypto-grade.
+
+The previous code operated in 4 steps:
+
+1. Generate a random byte 0 <= rand_tq <= 255
+2. Multiply it by BATADV_TQ_MAX_VALUE - tq
+3. Divide by 255 (= BATADV_TQ_MAX_VALUE)
+4. Return BATADV_TQ_MAX_VALUE - rand_tq
+
+This would apperar to scale (BATADV_TQ_MAX_VALUE - tq) by a random
+value between 0/255 and 255/255.
+
+But!  The intermediate value between steps 3 and 4 is stored in a u8
+variable.  So it's truncated, and most of the time, is less than 255, after
+which the division produces 0.  Specifically, if tq is odd, the product is
+always even, and can never be 255.  If tq is even, there's exactly one
+random byte value that will produce a product byte of 255.
+
+Thus, the return value is 255 (511/512 of the time) or 254 (1/512
+of the time).
+
+If we assume that the truncation is a bug, and the code is meant to scale
+the input, a simpler way of looking at it is that it's returning a random
+value between tq and BATADV_TQ_MAX_VALUE, inclusive.
+
+Well, we have an optimized function for doing just that.

+
+The commit d60b8fc69ef2 ("batman-adv: disable ethtool link speed detection
+when auto negotiation off") disabled the usage of ethtool's link_ksetting
+when auto negotation was enabled due to invalid values when used with
+tun/tap virtual net_devices. According to the patch, automatic measurements
+should be used for these kind of interfaces.
+
+But there are major flaws with this argumentation:
+
+* automatic measurements are not implemented
+* auto negotiation has nothing to do with the validity of the retrieved
+  values
+
+The first point has to be fixed by a longer patch series. The "validity"
+part of the second point must be addressed in the same patch series by
+dropping the usage of ethtool's link_ksetting (thus always doing automatic
+measurements over ethernet).
+
+Drop the patch again to have more default values for various net_device
+types/configurations. The user can still overwrite them using the
+batadv_hardif's BATADV_ATTR_THROUGHPUT_OVERRIDE.

+The gateway client code can try to optimize the delivery of DHCP packets to

+the client can be optimized by looking up the destination via the chaddr of
+the DHCP packet.
+
+But the chaddr is currently only done when chaddr is fully inside the
+non-paged area of the skbuff. Otherwise it will not be initialized and the
+unoptimized path should have been taken.
+
+But the implementation didn't handle this correctly. It didn't retrieve the

+uninitialized memory.

+Subject: batman-adv: Fix own OGM check in aggregated OGMs
+
+The own OGM check is currently misplaced and can lead to the following
+issues:
+
+For one thing we might receive an aggregated OGM from a neighbor node
+which has our own OGM in the first place. We would then not only skip
+our own OGM but erroneously also any other, following OGM in the
+aggregate.
+
+For another, we might receive an OGM aggregate which has our own OGM in
+a place other then the first one. Then we would wrongly not skip this
+OGM, leading to populating the orginator and gateway table with ourself.
+
+The latter seems to not only be a cosmetic issue, but there were reports
+that this causes issues with various subsystems of batman-adv, too. For
+instance there were reports about issues with DAT and either disabling
+DAT or aggregation seemed to solve it.
+
+Fixing these issues by applying the own OGM check not on the first OGM
+in an aggregate but for each OGM in an aggregate instead.

+
+It seems that due to a copy & paste error the void pointer
+in batadv_choose_backbone_gw() is cast to the wrong type.
+
+Fixing this by using "struct batadv_bla_backbone_gw" instead of "struct
+batadv_bla_claim" which better matches the caller's side.
+
+For now it seems that we were lucky because the two structs both have
+their orig/vid and addr/vid in the beginning. However I stumbled over
+this issue when I was trying to add some debug variables in front of
+"orig" in batadv_backbone_gw, which caused hash lookups to fail.

+Subject: batman-adv: mcast/TT: fix wrongly dropped or rerouted packets
+
+The unicast packet rerouting code makes several assumptions. For
+instance it assumes that there is always exactly one destination in the
+TT. This breaks for multicast frames in a unicast packets in several ways:
+
+For one thing if there is actually no TT entry and the destination node
+was selected due to the multicast tvlv flags it announced. Then an
+intermediate node will wrongly drop the packet.
+
+For another thing if there is a TT entry but the TTVN of this entry is
+newer than the originally addressed destination node: Then the
+intermediate node will wrongly redirect the packet, leading to
+duplicated multicast packets at a multicast listener and missing
+packets at other multicast listeners or multicast routers.
+
+Fixing this by not applying the unicast packet rerouting to batman-adv
+unicast packets with a multicast payload. We are not able to detect a
+roaming multicast listener at the moment and will just continue to send
+the multicast frame to both the new and old destination for a while in
+case of such a roaming multicast listener.

+Subject: batman-adv: mcast: fix duplicate mcast packets in BLA backbone from LAN
+
+Scenario:
+* Multicast frame send from a BLA backbone (multiple nodes with
+  their bat0 bridged together, with BLA enabled)
+
+Issue:
+* BLA backbone nodes receive the frame multiple times on bat0
+
+For multicast frames received via batman-adv broadcast packets the
+originator of the broadcast packet is checked before decapsulating and
+forwarding the frame to bat0 (batadv_bla_is_backbone_gw()->
+batadv_recv_bcast_packet()). If it came from a node which shares the
+same BLA backbone with us then it is not forwarded to bat0 to avoid a
+loop.
+
+When sending a multicast frame in a non-4-address batman-adv unicast
+packet we are currently missing this check - and cannot do so because
+the batman-adv unicast packet has no originator address field.
+
+However, we can simply fix this on the sender side by only sending the
+multicast frame via unicasts to interested nodes which do not share the
+same BLA backbone with us. This also nicely avoids some unnecessary
+transmissions on mesh side.
+
+Note that no infinite loop was observed, probably because of dropping
+via batadv_interface_tx()->batadv_bla_tx(). However the duplicates still
+utterly confuse switches/bridges, ICMPv6 duplicate address detection and
+neighbor discovery and therefore leads to long delays before being able
+to establish TCP connections, for instance. And it also leads to the Linux
+bridge printing messages like:
+"br-lan: received packet on eth1 with own address as source address ..."

+
+Issue:
+* BLA backbone nodes receive the frame multiple times on bat0,

+
+For unicast, a node will send only to the best backbone gateway
+according to the TQ. However for multicast we currently cannot determine
+if multiple destination nodes share the same backbone if they don't share
+the same backbone with us. So we need to keep sending the unicasts to
+all backbone gateways and let the backbone gateways decide which one
+will forward the frame. We can use the CLAIM mechanism to make this
+decision.
+
+One catch: The batman-adv gateway feature for DHCP packets potentially
+sends multicast packets in the same batman-adv unicast header as the
+multicast optimizations code. And we are not allowed to drop those even
+if we did not claim the source address of the sender, as for such
+packets there is only this one multicast-in-unicast packet.
+
+How can we distinguish the two cases?
+
+The gateway feature uses a batman-adv unicast 4 address header. While
+the multicast-to-unicasts feature uses a simple, 3 address batman-adv
+unicast header. So let's use this to distinguish.

+For multicast frames via batman-adv broadcast packets coming from the

+

+
+Room for improvements in the future: Ideally we would introduce the

+
+The batadv net_device is trying to propagate the needed_headroom and

+intensive reallocations using pskb_expand_head during the transmission.
+
+But the fragmentation code split the skb's without adding extra room at the

+transmissions over complex scenarios (batadv on vxlan on wireguard) because

+Subject: batman-adv: fix error handling
+
+Syzbot reported ODEBUG warning in batadv_nc_mesh_free(). The problem was
+in wrong error handling in batadv_mesh_init().
+
+Before this patch batadv_mesh_init() was calling batadv_mesh_free() in case
+of any batadv_*_init() calls failure. This approach may work well, when
+there is some kind of indicator, which can tell which parts of batadv are
+initialized; but there isn't any.
+
+All written above lead to cleaning up uninitialized fields. Even if we hide
+ODEBUG warning by initializing bat_priv->nc.work, syzbot was able to hit
+GPF in batadv_nc_purge_paths(), because hash pointer in still NULL. [1]
+
+To fix these bugs we can unwind batadv_*_init() calls one by one.
+It is good approach for 2 reasons: 1) It fixes bugs on error handling
+path 2) It improves the performance, since we won't call unneeded
+batadv_*_free() functions.
+
+So, this patch makes all batadv_*_init() clean up all allocated memory
+before returning with an error to no call correspoing batadv_*_free()
+and open-codes batadv_mesh_free() with proper order to avoid touching
+uninitialized fields.

+Subject: batman-adv: allow netlink usage in unprivileged containers
+
+Currently, creating a batman-adv interface in an unprivileged LXD
+container and attaching secondary interfaces to it with "ip" or "batctl"
+works fine. However all batctl debug and configuration commands
+fail:
+
+  root@container:~# batctl originators
+  Error received: Operation not permitted
+  root@container:~# batctl orig_interval
+  1000
+  root@container:~# batctl orig_interval 2000
+  root@container:~# batctl orig_interval
+  1000
+
+To fix this change the generic netlink permissions from GENL_ADMIN_PERM
+to GENL_UNS_ADMIN_PERM. This way a batman-adv interface is fully
+maintainable as root from within a user namespace, from an unprivileged
+container.
+
+All except one batman-adv netlink setting are per interface and do not
+leak information or change settings from the host system and are
+therefore save to retrieve or modify as root from within an unprivileged
+container.
+
+"batctl routing_algo" / BATADV_CMD_GET_ROUTING_ALGOS is the only
+exception: It provides the batman-adv kernel module wide default routing
+algorithm. However it is read-only from netlink and an unprivileged
+container is still not allowed to modify
+/sys/module/batman_adv/parameters/routing_algo. Instead it is advised to
+use the newly introduced "batctl if create routing_algo RA_NAME" /
+IFLA_BATADV_ALGO_NAME to set the routing algorithm on interface
+creation, which already works fine in an unprivileged container.

+## Status Page <a name="status"></a>
+The Status Page allows you to Start, Stop and restart the service as well as to check the result of these operations.
+
+#### Components
+- *Button* **Start**: Execute a Bird Daemon Service Start call. Operation's result is shown in the *Service Status* Text Box.
+- *Button* **Stop**: Execute a Bird Daemon Service Stop call. Operation's result is shown in the *Service Status* Text Box.
+- *Button* **Restart**: Execute a Bird Daemon Service Restart call. Operation's result is shown in the *Service Status* Text Box.
+- *Text Box* **Service Status**: Executes a Bird Daemon Service Status call. Operation's result is shown as plain text.
+
+#### Service Status common messages
+* *Running*: Service is running with no issues
+* *Already started*: You have clicked *Start* when the service was already running. No action taken.
+* *Stopped*: You have clicked *Stop* when the service was running. Service has been stopped.
+* *Already stopped*: You have clicked *Stop* when the service was already stopped. No action taken.
+* *Stopped ... Started*: You have pressed *Restart* when the service was running. The service has been restarted.
+* *Already stopped .. Started*: You have pressed *Restart* when the service was already stopped. The service has been started.
+* *Failed - ERROR MESSAGE*: There is a configuration or validation issue that prevents Bird to start. Check the *Error Message* and the Log Page to debug it and fix it.
+
+#### Error Examples
+1. Validation issues:
+  `bird4: Failed - bird: /tmp/bird4.conf, line 65: syntax error`
+
+If we check the file shown: `/tmp/bird4.conf` :
+```
+protocol bgp BGPExample {
+import Filter NonExistingFilter;
+}
+```
+We have entered an invalid (non-existent in this case) filter name. In order to fix this, write the correct Filter Name or remove its reference from the BGP Protocol Configuration Page and start the service again.
+
+2. Configuration issues:
+  ` bird4: Failed - bird: /tmp/bird4.conf, line 76: Only internal neighbor can be RR client`
+
+In this case, it is easy to spot that we have incorrectly selected the *Route Reflector Server* option incorrectly and we only need to untick it and start the service to solve it.
+
+Usuarlly, any configuration issue will be flagged appropiately through Bird service messages. However, in the event where you do not have enough information, please look for advice in either Bird's documentation or in the affected Protocol's documentation.
+
+## Log Page <a name="log"></a>
+The Log Page shows the last 30 lines of the configured Bird Daemon Log file. This information is automatically refreshed each second.
+
+#### Components
+- *Text Area* **Log File**: 30 lines text area that shows the Log file information
+- *Text* **Using Log File** and **File Size**: The first line of the Text Area is fixed and shows the file being used and its current size. **Please**, check this size information regularly to avoid letting the Log information overflow your Storage as it will make your service stop and prevent it to start until you fix it.
+- *Text* **File Contents**: The next 30 lines show information about the events and debug information happening live. Main information are state changes and *info, warning, fatal or trace*. If you hit any issue starting the service, you can investigate the issue from this page.
+
+
+## Overview Page <a name="overview"></a>
+The Overview Page includes the configuration of basic Bird Daemon settings such as UCI usage, Routing Tables definition and Global Options.
+
+### Bird File Settings (UCI Usage)
+This section enables/disables the use of this package's capabilities.
+
+#### Components
+- *Check Box* **Use UCI configuration**:
+  - If enabled, the package will use the UCI configuration generated by this web settings and translate it into a Bird Daemon configuration file.
+  - If disabled, the package will do nothing and you will have to manually edit a Bird Daemon configuration file.
+- *Text Box* **UCI File**: This file specifies the selected location for the translated Bird Daemon configuration file. Do not leave blank.
+
+### Tables Configuration
+This section allows you to set the Routing tables that will be used later in the different protocols. You can *Add* as many instances as required.
+
+#### Components
+- *Text Box* **Table Name**: Set an unique (meaningful) routing table name.
+> In some instances or protocols, you may want or be required to set a specific ID to a Table. In order to do this, please, follow this -right now- [manual procedure](https://github.com/eloicaso/bgp-bmx6-bird-docn/blob/master/EN/manual_procedures.md).
+
+
+### Global Options
+This section allows you to configure basic Bird Daemon settings.
+
+#### Components
+- *Text Box* **Router ID**: Set the Identificator to be used in this Bird Daemon instance. This option must be:
+> IPv4, this option will be set by default to the lowest IP Address configured. Otherwise, the identificator must be an IPv4 address.
+
+> IPv6, this option is **mandatory** and must be a HEX value (Hexadecimal). This package (bird6-uci), provides the HEX value *0xCAFEBABE* as a default value to avoid initial crashes.
+
+- *Text Box* **Log File**: Set the Name and Location of the Log file. By default, its location will be /tmp/bird{4|6}.log as the non-persistent partition.
+- *Mutiple Value* **Log**: Set which elements you want Bird Daemon to log in the configured file.
+> *Caution I*: if you select *All*, the other selected options will have no validity as, by definition, they are already included.
+> *Caution II*: Take into consideration that the more elements Bird has to log, the more space you will require to store this log file. If your storage is full, Bird will fail to start until you free some space to store its Log data.
+
+- *Multi Value* **Debug**: Set which Debug information elements you want Bird Daemon to log in the configured file.
+> *Caution I*: if you select *All*, the other selected options will have no validity as, by definition, they are already included.
+> *Caution II*: Take into consideration that the more elements Bird has to log, the more space you will require to store this log file (this is particularly critical in Debug as it can log MegaBytes of data quickly). If your storage is full, Bird will fail to start until you free some space to store its Log data.
+
+## General Protocols <a name="general"></a>
+The General Protocols Page includes the configuration of key OS Protocols or Network Basic Settings such as Kernel, Device or Static Routes.
+
+### Kernel Options
+This section allows you to set all the Kernel Protocols required to do Networking.
+> The first Kernel instance is the Primary one and must be left by default for OS usage. Do not set its "Table" or "Kernel Table" options.
+
+#### Components
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *List Value* **Table**: Select the Routing Table to be used in the Kernel Protocol instance.
+> The Primary Kernel Protocol cannot be empty.
+
+- *Text Box* **Import**: Set if the protocol must import routes and which ones.
+  - **all**: Accept all the incoming routes.
+  - **none**: Reject all the incoming routes.
+  - **filter filterName**: Call an existing filter to define which incoming routes will be accepted or rejected.
+- *Text Box* **Export**: Set if the protocol must export routes and which ones.
+  - **all**: Accept all the outgoing routes.
+  - **none**: Reject all the outgoing routes.
+  - **filter filterName**: Call an existing filter to define which outgoing routes will be accepted or rejected.
+- *Text Box* **Scan time**: Set the time between Kernel Routing Table scans. This value must be the same for all the Kernel Protocols.
+- *Check Box* **Learn**: Set this option to allow the Kernel Protocol to learn Routes form other routing daemons or manually added by an admin.
+- *Check Box* **Persist**: Set this option to store the routes learnt in the table until it is removed. Unset this option if you want to clean the routes on the fly.
+- *Text Box* **Kernel Table**: Select the specific exitisting Routing Table for this Protocol instance.
+> The Kernel Table ID must be previously set by the administrator during the Routing Table configuration. Currently (v0.3), this process is done manually. Please, follow this [manual procedure](https://github.com/eloicaso/bgp-bmx6-bird-docn/blob/master/EN/manual_procedures.md).
+
+### Device Options
+This section allows you to set all the Device *Protocol*. The Device *Protocol* is just a mechanism to bound the interfaces and Kernel tables in order to get its information.
+
+#### Components
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *Text Box* **Scan Time**: Set the time between Kernel Routing Table scans. This value must be the same for all the Kernel Protocols.
+
+### Static Options
+This section allows you to create the container for Routes definition. Static protocol instances allows you to manually create Routes that Bird will use and which Routing Table should hold this information. It also helps to manage routes by marking them (i.e. *Unreachable*, *Blocked*, ...).
+
+#### Components
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *List Value* **Table**: Select the Routing Table to be used in the Static Protocol instance.
+
+### Routes
+This section allows to set which Routes will be set in a specific Static Protocol and how these should be handled.
+
+#### Components
+- *List Value* **Route Instance**: Set which Static Protocol instance will contain this route infromation.
+> Routes require an existing Static Protocol as parent.
+
+- *Text Box* **Route Prefix**: Set the Route instance to be defined.
+> Examples of routes are:. 10.0.0.0/8 (IPv4) or 2001:DB8:3000:0/16 (IPv6)
+
+- *List Value* **Type Of Route**: This value will set the conditional settings. Options are:
+  - **Router**: Classic routes going through specific IP Addresses. 
+    - *Text Box* **Via**: Set the target IP Address to be used for Routing
+    > I.e. 10.0.0.0/8 via 10.1.1.1
+
+  - **MultiPath**: Multiple paths Route.
+    - *List of Text Box* **Via**: Set the target Route to be used for Routing. This option allows several instances of **Via** elements.
+    > I.e. 10.0.0.0/8 via 10.1.1.1
+    >            via 10.1.1.100
+    >            via 10.1.1.200
+
+  - **Special**: Special treated Route.
+    - *Text Box* **Attribute**: Block special consideration of routes.
+    > **unreachable**: Return route cannot be reached.
+    > **prohibit**: Return route has been administratively blocked.
+    > **blackhole**: Silently drop the route.
+
+  - **Iface**: Classic routes going through specific interfaces.
+    - *List Value* **Interface**: Select the target interface to route.
+
+  - **Recursive**: Set a static recursive route. Its next hope will depen on the table's lookup for each target IP Address.
+
+### Direct Protocol
+This section allows to set pools of *directly* connected interfaces. Direct Protocol instances will make use of the *Device* Protocol in order to generate routes between the selected interfaces.
+
+#### Components
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *Text Box* **Interfaces**: This is the key option allowing to *tie* the interfaces and create direct routes between different sides. Enter each interface's name you want to couple.
+  - If you leave this option empty, it will tie all the interfaces together.
+  - Each interface must be quoted: i.e. `"eth0"`
+  - Several interfaces must be entered comma-separated: i.e. `"eth0", "wlan0"`
+  - If you want to restrict this to specific interfaces, you have to enter them using its name or a pattern: i.e. All the ethernet interfaces `"eth*"`
+  - You are allowed to **exclude** specific interfaces by adding `-` before the interface name: i.e. Exclude all the Wireless interfaces `"-wlan*"`
+  > Example: All the wired interfaces (eth and em) but exclude all the wireless and point-to-point interfaces: `"eth*", "em*", "-wlan*", "-ptp_*"`
+
+> Current version 0.3 requires you to enter each interface you want to **include** or **exclude** manually. This will be enhanced in future versions.
+
+### Pipe Protocol
+This section allows to set instances of *linked* routing tables. Each instance will allow you to share the routes from a primary table to a secondary one.
+
+#### Components
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *List Value* **Table**: Select the **Primary** Routing Table to be used.
+- *List Value* **Peer Table**: Select the **Secondary** Routing Table to be used.
+- *List Value* **Mode**: Set if you want to work in *transparent* or *opaque* mode.
+  - **Transparent**: Retransmits all the routes and its attributes. Therefore, you get two identical routing tables. This is the default behaviour.
+  - **Opaque**: This mode is not recommended for new configurations and it is not recommended. Tables will only share the optimal routes and overwrite route's attributes with new ones (Pipe).
+- *Text Box* **Import**: Set if the protocol must import routes and which ones.
+  - **all**: Accept all the incoming routes.
+  - **none**: Reject all the incoming routes.
+  - **filter filterName**: Call an existing filter to define which incoming routes will be accepted or rejected.
+- *Text Box* **Export**: Set if the protocol must export routes and which ones.
+  - **all**: Accept all the outgoing routes.
+  - **none**: Reject all the outgoing routes.
+  - **filter filterName**: Call an existing filter to define which outgoing routes will be accepted or rejected.
+
+
+## BGP Protocol<a name="bgp"></a>
+The BGP Protocol Page includes all the settings to configure BGP Templates and BGP instances.
+BGP Templates and Instances share most of the options as Templates are meant to diminish the requirements on Instances.
+> An extreme example case could be the Template holding all the options and the Instance only referencing to the Template as the only option..
+
+### BGP Templates
+This section allows you to set BGP Templates, which are commonly used BGP configuration*themes* to reduce the number of repeated settings while adding BGP Instances.
+
+### BGP Instances
+This section allows you to set BGP Instances. The Instances are the ones starting the BGP Protocol and can, or not, use a BGP Template to re-use the common properties.
+> **Caution**: Any duplicated option between an Instance and a Template will resolve by using the Instance option and dismissing the Template one. **Instance** > *Template*.
+
+#### BGP Instance Specific Option
+- *List Value* **Templates**: Set the BGP Template that will feed the instance. Any option in the Template will be inherited.
+
+#### Common Options
+- *Check Box* **Disabled**: Set this Check Box if you do not want to configure and use this Protocol.
+- *Text Area* **Description**: Set a descriptive text to identify this protocol and what it does.
+- *Text Box* **Import**: Set if the protocol must import routes and which ones.
+  - **all**: Accept all the incoming routes.
+  - **none**: Reject all the incoming routes.
+  - **filter filterName**: Call an existing filter to define which incoming routes will be accepted or rejected.
+- *Text Box* **Export**: Set if the protocol must export routes and which ones.
+  - **all**: Accept all the outgoing routes.
+  - **none**: Reject all the outgoing routes.
+  - **filter filterName**: Call an existing filter to define which outgoing routes will be accepted or rejected.
+- *List Value* **Table**: Select the Routing Table to be used.
+- *List Value* **IGP Table**: Set the IGP Routing Table (Internal BGP). Bird uses the same Routing Table for both External BGP and Internal BGP by default.
+- *Text Area* **Source Address**: Set the local IP Address. By default the Router ID will be used.
+- *Text Area* **Local AS**: Set the local BGP Autonomous System ID.
+- *Text Area* **Local BGP Address**: Set the local BGP Autonomous System IP Address.
+- *Text Area* **Neighbor IP Address**: Set BGP neighbour's IP Address.
+- *Text Area* **Neighbor AS**: Set BGP neighbour's Autonomous System ID.
+- *Check Box* **Next Hop Self**: Overwrite Next Hop cost attributes with its own source address as next hop. Disabled by default as it is only used in some specific instances.
+- *Check Box* **Next Hop Keep**: Forward the same Next Hop information even in situations where the system would use its own source address instead. Disabled by default.
+- *Check Box* **Route Reflector Server**: Set if BGP instance must act as a Route Reflector Server and expect neighbours AS to act as clients
+- *Text Value* **Route Reflector Cluster ID**: Route Reflector service ID to avoid loops. This options is only allowed in the Server (not clients) and it is Router's ID by default.
+- *Text Box* **Routes Import Limit**: Set the maximum number of routes the protocol will import.
+- *List Value* **Routes Import Limit Action**: Set the action to apply if the *Routes Import Limit* is exceeded. Options are:
+  - **block**: Block any route exceeding the limit.
+  - **disable**: Stop the protocol.
+  - **warn**: Print Log warnings.
+  - **restart**: Restart the protocol.
+- *Text Box* **Routes Export Limit**: Set the maximum number of routes the protocol will export.
+- *List Value* **Routes Export Limit Action**: Set the action to apply if the *Routes Export Limit* is exceeded. Options are:
+  - **block**: Block any route exceeding the limit.
+  - **disable**: Stop BGP protocol.
+  - **warn**: Print Log warnings.
+  - **restart**: Restart BGP protocol.
+- *Text Box* **Routes Received Limit**: Set the maximum number of shared routes the Protocol must accept and remember (the **number** of imported routes is not affected by this option).
+- *List Value* **Routes Received Limit Action**: Set the action to apply if the *Routes Received Limit* is exceeded. Options are:
+  - **block**: Block any route exceeding the limit.
+  - **disable**: Stop BGP protocol.
+  - **warn**: Print Log warnings.
+  - **restart**: Restart BGP protocol.
+
+
+## Filters and Functions<a name="fnf"></a>
+The Filters and the Functions Page allows you to edit Bird Daemon Filter and Functions files without requiring you to go to command line.  Both Pages share the same code base and the only main change is where they are getting the files from. Therefore, and for documentation simplicity sake, both pages will be covered in this section.
+> From version 0.3 onwards:
+> The default and supported place to store filter files is under `/etc/bird{4|6}/filters`. 
+> The default and supported place to store function files is under `/etc/bird{4|6}/functions`. 
+
+> Current version 0.3 does not allow changing file names. You will have to change the default filenames through SSH. This will be enhanced in future versions.
+
+#### Components
+- *List Value* **Filter Files** / **Function Files**: Set the Filter or Function file to edit from the ones under `/etc/bird{4|6}/filters` / `/etc/bird{4|6}/functions`.
+> If you want to create a new Filter or Function file, use the **New File** element in the list.
+
+> The default behaviour is to allow administrators to create new files using this scheme:
+> */etc/bird{4|6}/filters/filter*-**TIMESTAMP**. *Timestamp* is: YYYYMMDD-HHMM. I.e. */etc/bird4/filters/filter-20170705-2030*
+> */etc/bird{4|6}/functions/function*-**TIMESTAMP**. *Timestamp* is: YYYYMMDD-HHMM. I.e. */etc/bird4/functions/function-20170705-2030*
+
+- *Button* **Load File**: Click this button to Load the file selected in the *{filter|function} Files* list. This button **must** be pressed in order to edit the target file.
+- *Read Only Text Box* **Editing File**: This Read-Only field is empty by default. It will get populated with the target file to edit. 
+> **Caution**: Only if this field shows a file path, the contents of the target file can be edited and saved. 
+
+- *Text Area* **File Contents**: This text area will show the contents of the file shown in the *Editting File*. Save the contents of this text area by pressing the Button **Submit**
+> Use **spaces** instead of **tabs** for indentation.
+
+> **Caveat**: If you save your filter or function using the *New File* option, until you refresh the page, the **saved** file will still appear as *New File*. However, the file will be created and correctly stored and you will be able to edit it with no problems.
+> After refreshing the page, your file will appear normally together with a new *New File* option.
+> This behaviour will be enhanced in future versions.
+
+#### Common Errors
+Most common errors produced by Filters and Functions are:
+
+- Syntax errors: `bird: /etc/bird4/filters/filter-20170507-0951, line 4: syntax error` 
+> This instances require you to check where your errors is following Bird's hints.
+
+- Non-existing filter: `bird: /tmp/bird4.conf, line 71: No such filter.`
+> Check your Filter name or define it in the **Filters Page**
+
+- Calls to functions not defined in the Functions files or not part of the Bird filter/function definition *language*: `, line 4: You can't call something which is not a function. Really.`
+> Check you Function definition, your call name or Bird's official documentation to get the right reference.
+
+#### Critical Errors
+There are some critical errors that could escape from first sight as Bird Daemon will start working *correctly*.
+
+If you set your Filter **without** *accept* or *reject* calls, your filter will fail to work and let all the routes pass by as accepted. This will be shown in the **Log Page**:
+
+Example: **Filter "doNothing"**
+```
+filter doNothing
+{
+    print "HelloWorld";
+}
+```
+This *wrong* filter has been used in our BGP instance and Bird Daemon runs correctly. However, if we check the **Log Page** we find:
+```
+2017-05-07 10:18:49 <ERR> Filter doNothing did not return accept nor reject. Make up your mind
+2017-05-07 10:18:49 <INFO> HelloWorld
+```
+> Do not leave any filter without *accept* or *reject* calls to avoid this wrong behaviour that will incurr in a waste of resources.

+## Known issues (v0.3):
+* There is an issue with pre-built images. It seems that the UCI-Default Scripts are not applied for some reason. If you face this situation, just copy both packages in your /tmp and and execute "opkg install PackageName.ipk --force-reinstall". It will overwrite your /etc/config/bird{4|6}, create a backup of this configuration.
+
+* LUCI Material Design Theme shows a "Loading page" in **Logs Page** preventing it to load. Moreover, the OpenWRT Theme crashes loading the **Log Page**.
+Please, go to `System -> Language and Style -> Design` and change it to any other avaiable Theme (*Bootstrap* or *Freifunk_Generic* are recommended).
+
+* There is a manual procedure to designate custom Routing Table IDs created through this package's UI. Please, visit [this page](https://github.com/eloicaso/bgp-bmx6-bird-docn/blob/master/EN/manual_procedures.md) for more details.
+
+## How to compile:
+Due to the existence of Routing's bird-openwrt packages, if you want to build your system using this repo's bird packages, you need to proceed as follows:
+
+
+* Add this github as a repository in feeds.conf. Alternatively, you could use a local git clone)
+```
+src-git birdwrt https://github.com/eloicaso/bird-openwrt.git
+
+```
+OR
+```
+src-link birdwrt /path/to/your/git/clone/bird-openwrt
+```
+
+* Disable OpenWRT-Routing repository to avoid getting the outdated package
+```
+# src-git routing https://github.com/openwrt-routing/packages.git
+```
+
+* Update and install all packages in feeds
+```
+./scripts/feeds update -a; ./scripts/feeds install -a
+```
+
+* Enable OpenWRT-Routing repository to fulfill bird{4/6} dependencies
+```
+src-git routing https://github.com/openwrt-routing/packages.git
+./scripts/feeds update routing; ./scripts/feeds install bird4 bird6
+```
+
+* Compile (Option 1) the whole OpenWRT image with the package included
+```
+make menuconfig -> Network -> Routing and Redirection -> Select bird*-uci
+                -> LuCI -> 3. Applications -> Select luci-app-bird*
+make V=99
+```
+
+* Compile (Option 2) the packet ( ! this method requires to compile its dependeces before using Option 1)
+```
+make package/feeds/birdwrt/bird{4/6}-openwrt/compile V=99
+```
+
+* Find your package in
+```
+[OpenWRT_folder]/bin/packages/{Architecture}/routing/bird{4/6}-uci_{Version}_{Architecture}.ipk
+[OpenWRT_folder]/bin/packages/{Architecture}/routing/luci-app-bird{4/6}_{Version}_{Architecture}.ipk
+```
+
+* Install your .ipk in your dev-environment (avoid CheckSum Missmatch issues)
+```
+scp bird{4/6}-uci_{Version}_{Architecture}.ipk user@IPAddres:/tmp
+
+On your Dev-Environment:
+opkg install bird{4/6}-uci_{Version}_{Architecture}.ipk --force-checksum
+```

+# Bird{4|6} UCI Packages Documentation
+*  BIRD Daemon's original documentation: http://bird.network.cz/?get_doc
+* Usage examples (Gitlab): https://gitlab.labs.nic.cz/labs/bird/wikis/home
+* Extra documentation in English & Catalan: https://github.com/eloicaso/bgp-bmx6-bird-docn
+* If you want to add new options to bird*-openwrt packages add a pull request or issue in: https://github.com/eloicaso/bird-openwrt
+
+### Options used in /etc/config/bird{4|6}
+> *Clarification*: Any reference to **{4|6}** in this document means that it applies to both Bird4 and Bird6 packages and configurations. Otherwise, the text will clarify which specific package is affected by it.
+
+#### CONFIGURATION SECTION 1: 'bird'
+Usage example :
+``` Bash
+config bird 'bird'
+    option use_UCI_config '1'
+    option UCI_config_file '/tmp/bird4.conf'
+```
+
+* **use_UCI_config**: *Boolean*
+This option allows you to use package's UCI configuration translation instead of using the original Bird config file (hand-edited). If true/1, birdX init.d script will use the translation placed in "UCI_config_file". Otherwise, it will use the default "/etc/birdX.conf" configuration.
+**\[HINT**\] This could be used to allow multiple configurations and swap them easily.
+*Default: 0*
+
+* **UCI_config_file**: *String* File_path
+This option sets where will be placed the translation of the UCI configuration file.
+*Default: /tmp/birdX.conf*
+
+
+#### CONFIGURATION SECTION 2: 'global NAME'
+Usage example:
+```Bash
+config global 'global'
+    option log_file '/tmp/bird4.log'
+    option log 'all'
+    option debug 'off'
+    option router_id '172.16.1.6'
+```
+
+* **log_file**: *String* File_path
+This option sets the path of the file used to save Bird Log and Debug's information.
+*Default: /tmp/bird{4|6}.log*
+
+* **log**: *String/Enumeration* (all/off, info, warning, error, fatal, debug, trace, remote, auth, bug)
+This option allows you to set which information you want to save in the Log file.
+**\[HINT\]** Use the enumeration like: { info, waning, error }. Do not enter any extra option if you select "all" (Bird will fail to start).
+*Default: all*
+
+* **debug**: *String/Enumeration* ( all/off, states, routes, filters, interfaces, events, packets)
+This option allows you to set which **extra** debug information will be saved in the "log_file" file.
+**\[HINT\]** Use the enumeration like: { info, waning, error }. Do not enter any extra option if you select "all" (Bird will fail to start).
+*Default: off*
+
+* **router_id**: IP Address
+This option sets which will be the Router ID.
+**\[HINT\]** In **Bird4** this field is the lowest IP address (not loopback) among the existing interfaces by default (Optional property).
+In **Bird6** there is no default value and it is mandatory.
+
+* **listen_bgp_addr**: IP Address
+This option sets the IP address that Bird BGP instances will listen by default.
+*Default: 0.0.0.0*
+
+* **listen_bgp_port**: *Integer* Port
+This option sets the port that Bird BGP instances will listen by default.
+*Default: IP 0.0.0.0 and Port 179*
+
+* **listen_bgp_dual**: *Boolean*
+**\[Bird6\]** This option configures Bird6 BGP instances to listen only IPv6 or IPv4/6 BGP routes.
+
+
+#### <a name="table"></a>CONFIGURATION SECTION 3: 'table'
+Usage example:
+``` Bash
+config table
+    option name 'aux'
+```
+
+* **name**: *String*
+This option allows you to set the name of the auxiliar kernel tables used for Bird. This option is mandatory for most of the protocols.
+
+
+#### CONFIGURATION SECTION 4: 'kernel NAME'
+Usage example:
+``` Bash
+config kernel kernel1
+    option table 'aux'
+    option import 'all'
+    option export 'all'
+    option kernel_table '100'
+    option scan_time '10'
+    option learn '1'
+    option persist '0'
+    option disabled '0'
+```
+
+* **table**: *String*
+Set an auxiliary table for the current kernel routing instance. This table **MUST** exist as a [table](#table) instance.
+**\[HINT\]** If there is an Kernel protocol instance that uses the "main" kernel table, not using table/kernel_table options, this should be included before the rest of Kernel instances (which will use auxiliary tables).
+
+* **import**: *String/Filter* function
+This option delimits which routes coming from other protocols will be accepted. 
+Options are:
+**All/none**: allows to import all the routes or none of them.
+**Filter name**: \[import 'bgp_filter_in'\] the protocol will use the filter with the given name (Specified filter **must** exists in any file under /etc/bird{4|6}/filters/ folder).
+
+* export: String/Filter function
+This option delimits which routes going out from the protocol. This option allows filters in different manners:
+**All/none**: allows to export all the routes or none of them.
+**Filter name**: \[export 'bgp_filter_out'\] the protocol will use the filter with the given name(Specified filter **must** exists in any file under /etc/bird{4|6}/filters/ folder).
+
+* **kernel_table**: *Integer*
+This option sets the identification number of the Kernel table that will be used instead of the main one.
+*Default: main table (254)*
+
+* **scan_time**: *Integer*
+This option sets the time between checks to target kernel table.
+
+* **learn**: *Boolean*
+Set if kernel table will add the routes from other routing protocols or the system administrator.
+
+* **persist**: *Boolean*
+Set if Bird Daemon will save the known routes when exiting or if it will clean the routing table.
+
+* **disable**: *Boolean*
+This option sets if the protocol will be used or dismissed.
+*Default: 0*
+
+
+#### CONFIGURATION SECTION 5: 'device NAME'
+Usage example:
+``` Bash
+config device device1
+    option scan_time '10'
+    option disabled '0'
+```
+
+* **scan_time***: *Integer*
+This option sets the time between checks to the selected kernel table.
+
+* **disable**: *Boolean*
+This option sets if the protocol will be used or dismissed.
+*Default: 0*
+
+
+#### CONFIGURATION SECTION 6: 'static NAME'
+Usage example:
+``` Bash
+config static static1
+    option table 'aux'
+    option disabled '0'
+```
+
+* **table**: *String*
+Set an auxiliary table for the current static instance. This table **MUST** exist as a [table](#table) instance.
+**\[HINT\]** If there is an static instance that uses the "main" kernel table (not using table/kernel_table options), this should be included before the rest of static instances (which will use auxiliary tables).
+
+* **disable**: *Boolean*
+This option sets if the protocol will be used or dismissed.
+*Default: 0*
+
+
+#### CONFIGURATION SECTION 7 & 8: 'bgp NAME' & 'bgp_template NAME'
+This section merges two different configuration sections: BGP *instances* and *templates*. The first one is the basic BGP configuration part and the second one is the template used to minimize the number of options written in the configuration file for each unique instance. Both configuration sections have the same options but, when Bird finds duplicities, the instance will overwrite the template options.
+
+Usage examples:
+``` Bash
+# instance
+config bgp bgp1
+    option template 'bgp_common'
+    option description 'Description of the BGP instance'
+    option neighbor_address '172.16.1.5'
+    option neighbor_as '65530'
+    option source_address '172.16.1.6'
+    option next_hop_self '0'
+    option next_hop_keep '0'
+    option rr_client '1'
+    option rr_cluster_id '172.16.1.6'
+```
+
+``` Bash
+# template
+config bgp_template bgp_common
+    option table 'aux'
+    option import 'all'
+    option export 'all'
+    option local_address '172.16.1.6'
+    option local_as '65001'
+    option import_limit '100'
+    option import_limit_action 'warn'
+    option export_limit '100'
+    option export_limit_action 'warn'
+    option receive_limit '100'
+    option receive_limit_action 'warn'
+    option disabled '0'
+```
+
+* **template**: *String*
+This option states the template used for current BGP instance. This template MUST exist.
+
+* **description**: *String*
+This option allows to add a description of the bgp instance and its function.
+
+* **local_addr**: IP address
+This option allows to set the IP source of our Autonomous System (AS).
+
+* **local_as**: *Integer*
+This option allows to set the identification number of our AS number. This option is mandatory for each BGP instance.
+
+* **neighbor_addr**: IP address 
+Each BGP instance has a neighbor connected to. This option allows to set its IP address.
+
+* **neighbor_as**: *Integer*
+Each BGP instance has a neighbor connected to. This option allows to set its AS ID.
+
+* **next_hop_self**: *Boolean*
+If this option is true, BGP protocol will avoid to calculate the next hop and always advertise own "Router id" IP.
+*Default: 0*
+
+* **next_hop_keep**: *Boolean*
+If this option is true, BGP will always use the received next_hop information to redirect the route.
+*Default: 0*
+
+* **rr_client**: *Boolean*
+IF this option is true, the router will be set as Route Reflector and will treat the rest of the routers as RR clients.
+*Default: 0*
+
+* **rr_cluster_id**: *Integer*
+This option sets the identification number of the RR cluster. All the nodes in a cluster needs this option and share the same number.
+*Default: Router id*
+
+* **import_limit**: *Integer*
+This option sets the limit of routes that a protocol can import until take the action indicated in the import_limit_action.
+import_limit also counts filtered routes (even dropped ones).
+*Default: 0 (no limit)*
+
+* **import_limit_action**: *String*
+This option allows to decide the action to take when reached the limit of imported routes.
+Actions are: warn, block, restart, disable
+
+* **export_limit**: *Integer*
+This option sets the limit of routes that a protocol can export until take the action indicated in the export_limit_action.
+*Default: 0 (no limit)*
+
+* **export_limit_action**: *String*
+This option allows to decide the action to take when reached the limit of exported routes.
+Actions are: warn, block, restart, disable
+
+* **receive_limit**: *Integer*
+This option sets the limit of routes that a protocol can receive until take the action indicated in the receive_limit_action. receive_limit only counts accepted routes from the protocol.
+*Default: 0 (no limit)*
+
+* **receive_limit_action**: *String*
+This option allows to decide the action to take when reached the limit of received routes.
+Actions are: warn, block, restart, disable
+
+* **disable**: *Boolean*
+This option sets if the protocol will be used or dismissed.
+*Default: 0*
+
+
+#### CONFIGURATION SECTION 9: 'route' 
+Usage example:
+``` Bash
+config route
+    option instance 'static1'
+    option type 'router'
+    option prefix '192.168.9.0/24'
+    option via '10.99.105.159'
+
+config route
+    option instance 'static1'
+    option type 'special'
+    option prefix '192.168.2.0/24'
+    option attribute 'unreachable'
+
+config route
+    option instance 'static1'
+    option type 'iface'
+    option prefix '192.168.3.0/24'
+    option iface 'mgmt0'
+
+config route
+    option instance 'static1'
+    option type 'recursive'
+    option prefix '192.168.4.0/24'
+    option ip '192.168.1.1'
+
+config route
+    option instance 'static1'
+    option type 'multipath'
+    option prefix '192.168.30.0/24'
+    list l_via '172.16.1.5'
+    list l_via '172.16.1.6'
+```
+
+* **instance**: *String*
+This option indicates the route that the static protocol instance will apply.
+
+* **type**: *String*
+This option states the type of route that will be applied. Also defines the options available for it.
+Types are: 'router', 'special', 'iface', 'recursive' or 'multipath'.
+
+* **prefix**: IP address/network
+This option allows to define the network that you want to define.
+**\[router only\]** 
+**via**: IP Address
+This option indicates the IP address of the neighbor router where the routes will pass through.
+**\[special only\]**
+**attribute**: *String*
+This option will mark the behaviour of the route.
+Attribures are: 'blackhole', 'unreachable' or 'prohibit'.
+**\[iface only\]**
+**iface**: *String*
+This option indicates the interface used to redirect the BGP routes. Careful, the interface MUST exist, or Bird will fail to start.
+**\[recursive only\]**
+**ip**: IP address
+This option states the IP address which the next hop will depend on.
+**\[multipath only\]**
+This is a list, not an option. Use it as in the example, or check the UCI configuration documentation.
+**l_via**: IP address
+This list of IPs specifies the list (following the sequence) of routers that the route will follow as next hops.
+
+
+#### CONFIGURATION SECTION 10 & 11: 'filter NAME' & 'function Name'
+Filters are written in separated files under **/etc/bird{4|6}/filters/** and **/etc/bird{4|6}/functions/**. Their syntax can be found [here.](http://bird.network.cz/?get_doc&f=bird-5.html)
+The content of each filter and file file will be included in the resulting bird{4|6}.conf file without checking its syntax, so you could find errors during start time.
+
+* Clarification for any existing **v0.2** user: an automated upgrade path has been added to switch your old "filter" or "function" sections. It is safe to upgrade, but doing regular backups of your key files is always a good practise to avoid frustration.
