hello,
recently i noticed some entries in syslog like this:
Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid NEXT_HOP attribute -
neighbor address fd5b:a83:b06b:500::1

Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid route 172.20.212.0/26

i am not sure how to understand this log message.
i still have the route (including via nl-myb-1):
root@uk-myb-2:~ # birdc show route 172.20.212.0/26
BIRD 2.16.1 ready.
Table master4:

via fe80::bc1b:dbed:690a:6840 on wg.uk-jmp-2
and it's in the FIB as well:
root@uk-myb-2:~ # route -n get -inet 172.20.212.0/26
route to: 172.20.212.0
destination: 172.20.212.0
mask: 255.255.255.192
gateway: fe80::e0e3:b1bf:8d1d:abcd%wg.nl-myb-1
fib: 0
interface: wg.nl-myb-1
flags: <UP,GATEWAY,DONE>
recvpipe sendpipe ssthresh rtt,msec mtu weight expire
0 0 0 0 1420 1 0
so everything seems fine.
what is BIRD trying to indicate with this log message?
