We do that to get IPv6 to the ATM PVC customers - create a bridge-group
per PVC, and bridge between PVC, BVI (for IPv4 routing) and FastE0/6.x
(VLAN trunk to a Cat5500).

Works, but is ugly as hell - three different interfaces to be configured
per customer.

I'm waiting for 12.2(17)S (or whatever it's called) to show up to switch
to IPv6 ATM RBE, and clean up this ugliness.

Depends on the amount of interfaces and traffic level...
