ip in the ran

Has anyone thought about routing and route table convergence in this
scenario?  I've spoken to some colleagues that come from the legacy Internet
space and we discussed the apparent implication of the "edge" of the routed
cloud (from the core perspective) extending out to, say, the BTS.  It seems
implied that one's interior routing protocol must now handle a much larger
domain of addresses.  While I'm sure there are ways to introduce hierarchy
into this picture and make the routing more palatable, I don't believe such
an infrastructure has been contemplated on the legacy internet side.

btw, i hope i'm not in left field here, i can't claim to be a routing guru
or close to it.
