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