[RFC4684] defines Multi-Protocol BGP (MP-BGP) procedures that allow BGP speakers to exchange Route Target reachability information in order to limit the propagation of Virtual Private Networks (VPN) Network Layer Reachability Information (NLRI). [RFC4684] addresses both intra domain and inter domain distributions. Based on operational deployments, the current distribution model defined in [RFC4684] may cause some issue in specific scenarios. This document refines the route distribution rules for inter domain NLRIs in order to address these specific scenarios.
