<p class="MsoNormal">Hi.<br>
<br>
1. What output on MX for:<br>
# show bfd session extensive<br>
<br>
2. What output on BIRD for:<br>
> show bfd sessions<br>
<br>
3. Try to enable debug for BFD on bird and see what happens in log file.<br>
<br>
4. Use tcpdump on BIRD side to see all BFD packets are send or recieved.<br>
<br>
5. Do you have firewall on MX ? <br>
Check firewall, it must not block ports: UDP 3784, 4784<br>
for your neighbor`s IP.<br>

There is a bug in Junos 10.4 (and maybe early versions) with SRC address for BFD session if router have several IP`s on one iface.<br>
