Simplified Topology: I have got 2 linux boxes connected back to back. I am running bird 2.0.2 on both only for bfd sessions. int 1/1 (with ip 1.0.0.0.1/16) of linux1 is connected to int 1/2(with ip 1.0.0.2/16) of linux2 after configuring the bird.conf files I can see that bfd sessions are up. now if I create vlan interface on the these interfaces, and try creating bfd session over the vlan tagged interface, it doesnot work. can someone please help if I am any special configuration to indicate the vlan tagging or this scenario is not supported as of now. This scenario can be considered same as having bfd sessions over SVI interfaces (in terms of cisco terminology). -- Thanks, Rohit.
