We use RBE, which allows us to terminate bridged PDUs on routed interfaces
without BVIs. Are you terminating the PDUs on the box, or bridging them? I
would think that the subinterface would be all that you require, unless you
are bridging between VCs, which I didn't think possible:

6400-NRP1(config)#interface a0/0/0.1000 multi
6400-NRP1(config-subif)#bridge-g 1
6400-NRP1(config-subif)#bridge-g 2

Interface already configured within Bridge Group 1.

6400-NRP1(config-subif)#

Try using 'show bridge verbose', as such:

6400-NRP1#sh bridge ve
