    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 refines the route distribution rules of RT-Constrain to address the hierarchical RR scenarios.},
