Works fine here:
# brconfig -a
bridge0: flags=41<UP,RUNNING>
Configuration:
priority 32768 hellotime 2 fwddelay 15 maxage 20
ipfilter disabled flags 0x0
Interfaces:
xvif18.0 flags=3<LEARNING,DISCOVER>
port 11 priority 128
xvif3.0 flags=3<LEARNING,DISCOVER>
port 10 priority 128
xvif2.0 flags=3<LEARNING,DISCOVER>
port 9 priority 128
vlan0 flags=3<LEARNING,DISCOVER>
port 5 priority 128
/etc/rc.conf has defined:
auto_ifconfig=NO # config all avail.
interfaces
net_interfaces="re0 wm0 vlan0 bridge0 carp0" # used only if above
is NO
And
/etc/ifconfig.bridge0 :
create
!brconfig $int add vlan0
up
Then I define my interfaces in the configs of DOMUs like that:
vif = [ 'mac=aa:00:00:00:01:f0, bridge=bridge0' ]
