We might need some additional information about your particular situation to be able to give a really good answer. But in general the purpose of configuring bridge-group 1 is to allow the router to process non-IP traffic, such as IBM SNA, and to allow DLSW to forward that traffic (encapsulated in IP). So there is no need for the IP address on the interface as far as DLSW is concerned. The IP address on the interface allows non-SNA IP traffic to be routed on that interface.
So in your new environment where you are putting the bridge-group on the subinterface, will there be any IP traffic sent in that VLAN? If so it needs an IP address. If no IP traffic in that VLAN then it does not need an IP address.
If that does not sufficiently answer your question then we need some additional clarification of the situation. What kind of traffic will be carried in that VLAN? How do you want it to be forwarded? What happened to the IP traffic that used to be processed on that interface?
