BIRD is complaining that various peers are sending BFD packets with an
unknown session id.
Anyone have thoughts on this?
The logs look like this:
2024-02-07 23:44:14 <RMT> bfd1: Bad packet from YOUR_IP - unknown
session id (SOME_INTEGER)
Those marked with an asterisk were doing this yesterday, so prior to the
reboot of rs2.
