Carrying Protocol Independent Multicast - Sparse Mode (PIM-SM) in Any-Source Multicast (ASM) Mode Trees over Multipoint LDP (mLDP)
RFC 7442

Just a small question here:

   The reader of this document is expected to be familiar with PIM-SM
   [RFC4601] and mLDP [RFC6388].

Then why is 4601 listed as an informative reference (while 6388 is, correctly, normative)?

As mentioned by Carlos in his OPS-DIR review.

Introduction:

CMP: Overall, the introduction is a bit hard to parse. It contains a number of assumptions and expectations of the reader and notes. I suggest these paragraphs be taken out into a separate subsection of the Intro.

   The first mechanism, described in Section 3, is optional for
   implementations, but the second mechanism, described in Section 4, is
   mandatory for all implementations claiming conformance to this
   specification.

CMP: This being a STD Track document, is “mandatory” the same as “REQUIRED” (see Section 1.1)? Is “optional” the same as “OPTIONAL”?

CMP: A nit here as well, the pointers to the Sections have a wrong offset (should be S2 and S3).


Nits:

CMP: Sometimes the text talks about “Source Active Auto-Discovery” and others about “BGP Source Active Auto-Discovery”. See example below, I think it should normalize on one of them:
 2.1 Originating Source Active Auto-Discovery Routes (Mechanism 1) ..  5
 2.2 Receiving BGP Source Active Auto-Discovery Route by LSR  .......  6

Thanks for the addition from Tero's review.  Here is a link in case anyone is interested and didn't see it:

In the introduction, I am unable to parse this sentence:

   In a deployment scenario where the service provider has provisioned
   the network in such a way that the Rendezvous Point (RP) for a
   particular ASM group G is always between the receivers and the
   sources.

I think maybe you want to say:

   Consider a deployment scenario where the service provider has provisioned
   the network in such a way that the Rendezvous Point (RP) for a
   particular ASM group G is always between the receivers and the
   sources.
