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? //Jon
