intend to add more and do anycasting). the other peer will be a

It is the route to the virtual IP on the route client that I want

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

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

What about output from these commands:

birdc show protocols all Peer
<br>
birdc show route all protocol Peer
<br>
birdc show route all export Peer
<br>
netstat -rn

?
