Moreover, I've added hostid bits in the MAC to avoid that multiple servers that shares the same configuration (failover), will have the same epair MAC address, as pointed out by Olivier. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"

Hartmann --- I have faced this problem on recent CURRENT (FreeBSD 12.0-CURRENT #36 r329150: Mon Feb 12 06:30:47 CET 2018 amd64, VIMAGE kernel). Creating a bunch of epairs attached to bridges render the VIMAGE-based virtual network unusable as long as the MAC addresses is not setup manually: dmesg output, watch out the MAC=02:ce:d0:00:07:0a, which seems to occur multiple times.
