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.

I think it is caused by that vlan ifaces are brought up after bridge ifaces. If you have time you can dig the rc scripts.

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.

Can box on HP#1 ping another box on HP#2?



OTOH: From the vlan(4) manpage I get this:

Nah, things should work at least for small data generated by ping.
