In the following, I will refer to draft-ietf-pim-4601bis as simply
"4601bis".
RFC 4601 has been updated by several RFCs:
RFC 5059 Bootstrap Router (BSR) Mechanism for Protocol
Independent Multicast (PIM)
RFC 5796 Authentication and Confidentiality in Protocol
Independent Multicast Sparse Mode (PIM-SM)
Link-Local Messages
RFC 6226 PIM Group-to-Rendezvous-Point Mapping
4601bis refers to RFC 5059 in Section 3.7. The new text is identical to
the text in RFC 4601, although the reference in RFC 4601 is to the
Internet Draft that became RFC 5059.
4601bis makes no reference to RFC 5796. Given that RFC 5796 alters the
preferred IPsec solution (AH is "recommended" in RFC 4601, while RFC
5796 says that implementations "MUST support ESP and MAY support AH"),
and given that RFC 5796 provides considerable detail on the use of IPsec
to protect link-local messages for PIM-SM, RFC 5796 should be
specifically referenced in Section 6.3 of 4601bis.
4601bis makes no reference to RFC 6226. Given that RFC 6226 alters the
algorithm for determining the Rendezvous Point, RFC 6226 should be
specifically mentioned in Section 3.7 of 4601bis. The authors should
also consider whether to eliminate Section 4.7.1 and replace it with a
pointer to RFC 6226, to reduce it and add a pointer to RFC 6226, or to
leave it unchanged.
Suggested text for some of these changes has been supplied to the
authors of 4601bis.

Abstract
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) feature that lacks sufficient deployment
experience.
