Hi There is small thread about it: http://bird.network.cz/pipermail/bird-users/2017-March/011055.html The offered patch is in Git in master branch, but not in the last released 1.6.x branch. I thought about full VRF support for BIRD, my ideas are like: 1) VRFs defined in BIRD config. They are matched with VRF devices in kernel. 2) Instead of having one pool of interfaces, interfaces are automatically split to VRFs based on kernel scan. 3) Protocols (and routing tables) have option 'vrf', which assigns them to appropriate VRF, which means they only consider interfaces from that VRFs, resolve neighbors inside that VRFs and their sockets are bound to that VRFs. 4) Some specific protocols (e.g. pipe) could be associated with multiple VRFs.
