Salut fellow bird users, we recently tried to simplify the bfd configuration and replaced our existing configuration with the following:
--------------------------------------------------------------------------------
# Using BFD virtually everywhere, enable it globally
protocol bfd { }
...
protocol bgp incoming_r3ge {
local as myas;
direct;
bfd on;
...
--------------------------------------------------------------------------------
And now bird repots every second the following message:
--------------------------------------------------------------------------------
2024-08-08 11:00:15.727 <ERR> bfd1: Socket error: Destination address required
--------------------------------------------------------------------------------
The router has various interfaces, some tunnel, some wireguard tunnel,
some bridges, etc. and I have a bit trouble to spot, what is causing the
error message.
All interfaces that are used for BGP obviously have an IP address , but
many bfd sessions are actually down that I'd expect to be up:

--------------------------------------------------------------------------------
(excluding the two 2a0a:e5c0:10:1:.. ones, they don't have bfd enabled
at the moment)
Is using protocol bfd {} actually *not* supported?
Best regards,
Nico
