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.

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
