This document specifies how Bidirectional Forwarding Detection (BFD)
for multipoint networks can provide sub-second failover for routers
that participate in Protocol Independent Multicast - Sparse Mode
(PIM-SM). An extension to the PIM Hello message used to bootstrap a
point-to-multipoint BFD session is also defined in this document.

This document is a product of the Protocols for IP Multicast 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.
