Hi Seunghwan,
Sorry for my late response (had two weeks of holiday).
Your BFD protocol block doesn't mention any interfaces. The
documentation states (see
https://bird.network.cz/?get_doc&v=20&f=bird-6.html#ss6.2) that
shouldn't be needed however:

Hi Seunghwan,
Thanks. I'll take a look shortly.
Cheers,
Kees

Hi,
Yes we have; multiple times.
Could you please provide a full configuration? (Feel free to remove
passwords and such, obviously.)

Hello K.
Is not working.
Have you ever rebooted(# shutdown -r now) with your settings?
Still, only the BGP is established and the BFD state remains in Init.
Regards.

Sorry, I was unable to respond yet.
In our config I explicitely defined what interfaces should use bfd, for
example:

Hello K.
What does "disabled" setting mean?
This is my configuration
==
protocol bfd {
multihop {
min rx interval 300 ms;
min tx interval 300 ms;
multiplier 3;
};
}
protocol bgp as1 {
import all;
Hi K.
I've already tried capturing tcpdump.
BIRD's BFD neighbor was captured sending packets, but the packets sent by
BIRD were not captured.
In this state, BIRD's BFD packets were captured after restarting BFD
protocol.
The BFD packet was captured Only after restarting the BFD protocol .
Is there
Hi Seunghwan,
If you're sure no packets were dropped, it might make sense to use
tcpdump(8) or alike to ensure the BFD packets are really there.

Kees

Hello K.
Thanks for checking in this issue.
But, I can't understand.
If it was because of the iptables, it would have been a problem for BGP as
well.
And I'm not using iptables rules, So Any packets weren't dropped.
* iptables status

Hi Seunghwan,
It might be your problem isn't BIRD but packet filter related.
Please check the BFD packets are allowed in iptables c.q. netfilter
using the correct ports and/or addresses.
A possible reason why it starts working after a manual protocol restart
is a ESTABLISHED, RELATED rule.
