Abstract:
The Route Constrain address family can be used by a BGP speaker to
signal a neighbor its interest in receiving only the routes with a
matching route target (RT) extended community. This signaling is
afi-safi agnostic; the sender of a route constrain NLRI with an RT
expresses its interest in receiving routes with that RT for all afi-
safi. The ability to further scope a given RT to a list of afi-safi
would simplify network operations; then optimal route filtering would
no longer require that the set of RTs used for different afi-safi be
disjoint.
This document proposes a simple extended community based backward
compatible method to associate the list of afi-safi of interest to a
route constrain NLRI and discusses the operational procedure.
