You said you wanted routers that followed the RFC. The RFC does not mention list AS_PATH length as a route selection criteria. I have been told that the draft for the next rev specifically prohibits using AS_PATH length as a route selection criteria.

Patently false. In particular, the spec allows an implementation to invoke local policy when computing the local preference of a route. An implementation can reasonably incorporate the AS path length in its local preference calculations as part of its policy. Tony
