This is where good use of clusters and logical network design are
necessary, but I don't think this is a route-reflector specific problem,
more a general networking problem once your network starts groing and
you start deploying a more complex edge/core based topology. I don't
think this is a reason to not use reflection as oppossed to full mesh.
