    abstract =  {This document specifies Protocol Independent Multicast - Sparse Mode (PIM-SM). PIM-SM is a multicast routing protocol that can use the underlying unicast routing information base or a separate multicast-capable routing information base. It builds unidirectional shared trees rooted at a Rendezvous Point (RP) per group, and optionally creates shortest-path trees per source. This document obsoletes RFC 2362, an Experimental version of PIM-SM. {[}STANDARDS-TRACK{]}},
