Technical Summary
This document describes procedures for using Bidirectional Forwarding
Detection (BFD) for multipoint networks to detect data plane failures
in Multiprotocol Label Switching (MPLS) point-to-multipoint (p2mp)
Label Switched Paths (LSPs) and Segment Routing (SR) point-to-
multipoint policies with SR-MPLS data plane.
Furthermore, this document also updates RFC 8562 and recommends the
use of an IPv6 loopback address (:::1/128) and discourages the use of
an IPv4 loopback address mapped to IPv6.
It also describes the applicability of LSP Ping, as in-band, and the
control plane, as out-band, solutions to bootstrap a BFD session.
It also describes the behavior of the active tail for head
notification.
