if_bridge on a vlan-trunk

[Jon Otterholm]

Hi.

Does anyone know if it is possible to put a transparent bridge on a
vlan-trunk?

A working solution is to create a bridge for each vlan, but I would
prefer to have one bridge instead of several hundreds of them.

Is this doable?

In my lab environment I use a dual em(4) nic.

What would the drawbacks be if I create ~1500 if_bridge and attached
each vlan-sub-if from each physical interface to their own bridge? Would
this work?
