Assume I have hierarchical IGP with 10,000 nodes. Most PEs send service traffic to the local hubs only. Sporadically they may send traffic to other PEs in other areas - say to 1% of them. Service routes and most of remote next hops are dropped by RT filtering. Tell me why do you propose a mechanism which puts burden on network elements by blasting them with information they are never interested in ? Leave alone that such information is completely not needed also on the P routers in the core area and other areas. Thx, R.
