Abstract
This document defines Multicast Virtual Private Network (VPN) extensions and procedures that allow fast failover for upstream failures by allowing downstream Provider Edges (PEs) to consider the status of Provider-Tunnels (P-tunnels) when selecting the Upstream PE for a VPN multicast flow. The fast failover is enabled by using "Bidirectional Forwarding Detection (BFD) for Multipoint Networks" (RFC 8562) and the new BGP Attribute, BFD Discriminator. Also, this document introduces a new BGP Community, Standby PE, extending BGP Multicast VPN (MVPN) routing so that a C-multicast route can be advertised toward a Standby Upstream PE.
