This document discusses the use of Bidirectional Forwarding Detection (BFD) for multi-point networks to provide nodes that participate in Protocol Independent Multicast - Sparse Mode (PIM-SM) with the sub- second convergence. Optional extension to PIM-SM Hello, as specified in RFC 7761, to bootstrap point-to-multipoint BFD session. also defined in this document.
