[c-nsp] Extracting VLAN from brige-group's BVI

Please consider a 1721 router bridging Ethernet
VLAN frames across its serial link:

  !
  ! 1721 - Router1
  !
  interface Serial0
   bridge-group 1
  interface FastEthernet0
   bridge-group 1
  interface BVI 1
   ip address 10.0.0.1 255.255.255.0

A couple of VLANs is carried over the bridge.

As shown above, BVI1 is logically attached to the
"untagged" VLAN. Is there a way to attach the BVI
to a tagged VLAN instead? The purpose is to move
the management of the 1721 router (at 10.0.0.1) to
VLAN id=10.

I was expecting to be able to configure something
like this:

  interface BVI 1
   encapsulation dot1q 10
   ip address 10.0.0.1 255.255.255.0

But the syntax is invalid.

Please advise.
