    abstract =  {This document specifies the use of Bidirectional Forwarding Detection (BFD) for multipoint networks to provide nodes that participate in Protocol Independent Multicast - Sparse Mode (PIM-SM) with sub-second convergence. An extension to the PIM Hello message used to bootstrap point-to-multipoint BFD sessions is also defined in this document.},
