1. Motivation
1.1. Overview of PIM-SM
Protocol Independent Multicast - Sparse Mode (PIM-SM) was first
published as [RFC2117] in 1997. This version was then obsoleted by
[RFC2362] in 1998. The protocol was classified as Experimental in
both documents. The protocol specification was then rewritten in
whole and advanced to Proposed Standard as [RFC4601] in 2006.
Considering its multiple independent implementations developed and
sufficient successful operational experience gained, the PIM WG
decided to advance the PIM-SM protocol to Internet Standard. The
conducted survey and this document are part of the work.
1.2. Requirements of RFCs 2026 and 6410
[RFC2026] defines the stages in the standardization process, the
