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
In Cisco IOS, this falls under the BGP decision process in selecting a route. So in an indirect way, this is already implemented. To be more exact in terms of the RFC, I suppose a match clause could be implemented based on path length, but this can be done already with a regular expression. Either way, the capability is there. -Chris
