This document defines an extension to BGP route reflectors. On route
reflectors, BGP route selection is modified in order to choose the
best route from the standpoint of their clients, rather than from the
standpoint of the route reflectors themselves. Depending on the
scaling and precision requirements, route selection can be specific
for one client, common for a set of clients, or common for all
clients of a route reflector. This solution is particularly
applicable in deployments using centralized route reflectors, where
choosing the best route based on the route reflector's IGP location
is suboptimal. This  facilitates, for example, a "best exit point"
policy ("hot potato routing").

The solution relies upon all route reflectors learning all paths that
are eligible for consideration. BGP route selection is performed in
the route reflectors based on the IGP cost from configured locations
in the link-state IGP.

This document is a product of the Inter-Domain Routing Working Group of the IETF.

This is now a Proposed Standard.
