You need to get the traffic into vlans somehow - I thought about
suggesting this but hadn't worked out how to do it, but thinking more
it might be possible with vether.
Referring to the original diagram:

So you could have:
vether0: just configured "up" is probably enough
vlan{1,2,3}: vlandev vether0
bridge0: vether0<>gif0
bridge1: fxp1<>vlan1
bridge2: fxp2<>vlan2
bridge3: fxp3<>vlan3
gif0: tunnel between routerA<>routerB
If trying this, pay attention to MTUs and make sure that large
packets work in both directions.
