Perhaps we should first agree that there is a need a *short term* solution for both IPv4 and IPv6. The following (from Tony's e-mail on 5/26/2008) is relevant to the discussion on whether there is such a need: Well, Ross Callon has been quoted as saying that the Juniper implementation will have no problems up through many millions of routes. Now, conceptually, that could happen tomorrow. However, at the current growth rates, that's likely to be many years.
The routing table size problem is not the only problem. There are many enterprise sites that want to do low-cost multihoming, they want to be good citizens to the Internet and don't want to inject more specifics, and they want to control their ingress traffic flows.
