Hi!
I recently upgraded my system to 11-CURRENT (FreeBSD 11.0-CURRENT #0=20
r295087: Sun Jan 31 10:21:31 CET 2016) and after that all of my other=20
devices in the network complains about arp-flapping:
arp: 172.25.0.1 moved from 00:00:24:d0:9e:5d to 02:e8:ea:15:66:00 on re0
arp: 172.25.0.1 moved from 02:e8:ea:15:66:00 to 00:00:24:d0:9e:5d on re0
arp: 172.25.0.1 moved from 00:00:24:d0:9e:5d to 02:e8:ea:15:66:00 on re0
It seems to be flapping between the virtual mac of my bridge interface=20
and the actual mac adress on the physical interface. This was not the=20
case when i ran FreeBSD 10.2. Is there some settings I need to do?
