Abstract

The Route Target (RT) Constrain mechanism specified in RFC 4684 is used to build a route distribution graph in order to restrict the propagation of Virtual Private Network (VPN) routes. In network scenarios where hierarchical route reflection (RR) is used, the existing RT-Constrain mechanism cannot build a correct route distribution graph. This document describes the problem scenario and proposes a solution to address the RT-Constrain issue in hierarchical RR scenarios.
