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 it
optionally creates shortest-path trees per source.
This document obsoletes RFC 4601 by replacing it, addresses the
errata filed against it, removes the optional (*,*,RP), PIM Multicast
Border Router features and authentication using IPsec that lack
sufficient deployment experience (see Appendix A), and moves the PIM
specification to Internet Standard.
This document is a product of the Protocols for IP Multicast Working Group of the IETF.
This is now an Internet Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
