Ok, i have DNS running on one peer (route client) and listening on a
virtual sub-interface (I intend to add more and do anycasting). the
other peer will be a route server.
It is the route to the virtual IP on the route client that I want to
propagate to the route server.

Well, 1: which routes you expect your bird to propagate to peer?
169.254.0.0/16 network. must NOT be routed anyway.
2: ports out otput of "show protocols all " command here please.
3: show your FULL and UNCUT config file.
4: ifconfig -a

hello,
I have two ubuntu 12.04 linux servers running bird 1.3.8 and peered
with
each other.
The routes from each show in both routing tables.
I installed centos 6.3 on an (identically configured) different set of
servers and copied the configuration files. I see peering
established but
no
routes in both routing tables. It doesnt work when peered with the
ubuntu
servers either.
Please what may be wrong? Or am I just missing something?
Actually, when i do "show route" from birdc> i dont get any results
Sorry my crystal ball is unaligned how about a few bird.conf
snippets to
calibrate it?
What about output from these commands:
birdc show protocols all Peer
birdc show route all protocol Peer
birdc show route all export Peer
netstat -rn
?
