Hello there,
I get the error message:
"<ERR> bfd1: Socket error: Destination address required"
(ubuntu 22.04, bird via ppa 2.15.1) running BFD and MP-BGP via IPv6 over
wireguard interfaces. Not all BGP neighbors are reachable.
Relevant (I hope) config:
log "/var/log/bird/bird.log" all;
protocol device {
}
protocol bfd {
accept ipv6 direct;
interface "wg_blue*";
interface "wg_green" {
multiplier 3;
interval 500 ms;
};
neighbor 2001:db8:f000::2 dev "wg_green" local 2001:db8:f000::1;
neighbor 2001:db8:f000:ffff::2 dev "wg_blue2" local
2001:db8:f000:ffff::1;
neighbor 2001:db8:f000:fffc::5 dev "wg_blue1" local
2001:db8:f000:fffc::1;
neighbor 2001:db8:f000:fffc::4 dev "wg_blue1" local
2001:db8:f000:fffc::1;
neighbor 2001:db8:f000:fffc::3 dev "wg_blue1" local
2001:db8:f000:fffc::1;
neighbor 2001:db8:f000:fffc::2 dev "wg_blue1" local
2001:db8:f000:fffc::1;
}
protocol bgp EXAMPLE {
local as 65001;
neighbor 2001:db8:f000::2 as 65044;
direct;
med metric yes;
ipv4 {
...
};
ipv6 {
...
};
bfd on;
}
If I remove the BFD config for the non-established BGP neighbors, the
error message disappears (although there are still non-established BFD
sessions for established BGP neighbors (BFD not yet confed on the other
end)).
At first I did not create neighbor statements for BFD, then I added
"dev" and "local" options - no improvement.
No revelations with "debug protocols all".
Any ideas? Thanks a lot!
Best,
fran
