Certain DHCP servers push a gateway outside of the assigned interface subnet, to support those situations, install a host route towards the gateway. If Gateway and IP are served in same network, openwrt quagga cannot learn routes (rip routes are not getting added, showing inactive) whereas working fine when Gateway and IP are in different network.
