Technical Summary 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 addresses errata filed against RFC 4601, and removes the optional (*,*,RP) and PIM Multicast Border Router features that lacks sufficient deployment experience. Working Group Summary There was very good feedback on the list over the last year, particularly during the last WGLCs. All comments were addressed to the satisfaction of those commenting. Document Quality There are several existing implementations of the protocol over the span of many years. Bharat Joshi, most particularly, had many recent comments that were all addressed in final fine tuning of the document. RFC7063 documents the features implemented in a survey report. The document shepherds verified that all the errata had been handled. Personnel Mike McBride & Bill Atwood are the document shepherd and Alvaro Retana is the responsible AD.
