DOI: 10.17487/RFC9780
This document describes procedures for using Bidirectional Forwarding
Detection (BFD) for multipoint networks to detect data plane failures
in point-to-multipoint MPLS Label Switched Paths (LSPs) and Segment
Routing (SR) point-to-multipoint policies with an SR over MPLS
(SR-MPLS) data plane.
Furthermore, this document updates RFC 8562 by recommending the use
of an IPv6 address from the Dummy IPv6 Prefix address block
100:0:0:1::/64 and discouraging the use of an IPv4 loopback address
mapped to IPv6.
In addition, this document describes the applicability of LSP Ping
(as an in-band solution) and the control plane (as an out-of-band
solution) to bootstrap a BFD session. The document also describes the
behavior of the active tail for head notification.
This document is a product of the Multiprotocol Label Switching Working Group
of the IETF.
This is now a Proposed Standard.
