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.

This document is a product of the BGP Enabled Services Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
