Hello Bill Thank you for a good and concise summary of the various strategies for routing scalability.
Related to your question about other BGP solutions, I am wondering how well strategy D covers the proposals by Paul Francis and others: - mapped BGP and - virtual aggregation. The former requires some extensions to BGP, in terms of announcing the proper attributes for the maps and also its own RIBs. Rephrasing strategy D to "Use plain old BGP with extensions" would capture the mentioned BGP based solutions as well. (Notice that Paul's presentation in the last meeting starts with "tries to minimize changes to BGP", is not the same as "use the old BGP".)
