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.
