Issue: vlan traffic not in the jail
Weird issue today...
I have a bridge with on the host, two jails, and a vlan in the jail.
The jails were networking just fine with their native vlan (1), but the
host would not pass 802.1q traffic to the jail.
If I created the vlan91 on the host, that would 'wake up vlan awareness
on the bridge'. I could then destroy the vlan91 on the host, and the
jail still passes traffic.
The Workaround:
host#ifconfig vlan91 create vlan 91 vlandev igb1 10.1.1.1/28; ifconfig
vlan91 destroy
Maybe something wrong with the bridge spanning tree implementation?
It's like that bridge was created before the vlans, and the non-native
vlans are pruned.
