Last Call Review of draft-ietf-rmt-pi-alc-revised-
The Security Considerations section looks reasonably thorough. It
might be a good idea for an IPsec expert to take another look at it,
as I am not very familiar with IPsec.
Section 1.3 indicates that the Any-Source Multicast (ASM) model of
multicast is defined in RFC 1112. That RFC does not actually use that
terminology, even though it may define the concept. The first RFC
that I can find that uses the term Any-Source Multicast is RFC 3569.
