Introduction This analysis provides supporting documentation to advance the Protocol Independent Multicast - Sparse Mode (PIM-SM) routing protocol from the IETF Experimental status to Proposed Standard. PIM-SM was first published as RFC 2117 [RFC2117] in 1997 and then again as RFC 2362 [RFC2362] in 1998. The protocol was classified as Experimental in both of these documents. The PIM-SM protocol specification was then rewritten in whole in order to more fully specify the protocol. It is this new specification that is to be advanced to Proposed Standard. 2. RFC 1264 Requirements Section 4.0 of RFC 1264 [RFC1264] describes the requirements for routing protocols to advance to Proposed Standard. Each requirement is listed below along with an explanation of how the requirement has been satisfied. 2.1. Documents Specifying the Protocol and Its Usage The authors of the new PIM-SM specification [RFC4601] have taken considerable care to fully specify the protocol operation. It removes all known ambiguities and tries to normalize corner cases that existed in the previous specification. It has been used to provide several interoperable implementations by developers that were not authors of the specification. These implementations will be described below. 2.2. Management Information Base A Management Information Base for PIM is currently specified in RFC 2934 [RFC2934]. This MIB has many implementations and has been used by network management applications for several years. Updates to this MIB to support IPv6 and other improvements based on operation experience are in progress in the PIM Working Group of the IETF. 2.3. Explicit Security Architecture The new PIM Sparse-Mode protocol specification contains an extensive security section explaining its security features and limitations. Data integrity protection and groupwise data origin authentication is provided for PIM protocol messages. Pusateri Informational [Page 2] RFC 4602 PIM-SM Proposed Standard Req. Analysis August 2006 2.4. Implementation Existence There are at least 4 known independent implementations of the new protocol specification, and there are over 6 independent implementations of a previous version (RFC 2362) of the specification. The new specification was carefully written to be backward compatible with the old specification allowingShow full document text
