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- neighbor address fd5b:a83:b06b:500::1 Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid route 172.20.212.0/26 withdrawn Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid NEXT_HOP attribute - neighbor address fd5b:a83:b06b:500::1 Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid route 172.20.212.0/26 withdrawn Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid NEXT_HOP attribute - neighbor address fd5b:a83:b06b:500::1 Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid route 172.20.212.0/26 withdrawn Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid NEXT_HOP attribute - neighbor address fd5b:a83:b06b:500::1 Mar 15 11:03:22 uk-myb-2 bird[60388]: nl-myb-1: Invalid route 172.20.212.0/26 withdrawn i am not sure how to understand this log message.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.
