To me, it would be a waste of IP to assign an address to the subinterface
fa0.3. Let the BVI interface have the address. This makes it alot simpler.

Sounds alright to me....but can interface fa0.3 be assigned an ip address if
it
is
also in the bridge-group?
interface fa0.2
encap isl 2
interface fa0.3
ip address <network 1.a>
encap isl 3
bridge-group 1
interface fa0.4
encap isl 4
bridge-group 1
inter bvi 1
ip address <network 2>
bridge 1 protocol ieee
bridge 1 route ip
