Only manually.

Yes. In rc.conf I have:
ifconfig_bridge0="addm vlan0 addm vlan2 up"
When I do from commandline:

# ifconfig bridge0 addm vlan0 addm vlan2 up

it works. Strange.

Does not help. Let me show you the structure:

HP 2524 #1 --- xl0 (vlan0 ID:11) -- bridge0 -- xl1 (vlan2 ID:11) -- HP2524 #2

The switches can not 'talk' to each other via the bridge.

OTOH:
