Maybe, maybe not. You are skipping over a lot of significant detail.
What type of mobility are you trying to solve? Networks moving around?
Hosts moving around? The implications for what the global routing system
must know about the moving entities are big. Also, what are the
requirements for speed of updates? The type of mobility that is
requested in today's networks goes all the way to up to the speed that
is capable of avoid interruptions in VoIP calls. This may be possible to
do in the routing system, too, but the requirements are very different
from merely supporting, say, site multihoming.
