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.
