I have reviewed this document as part of the Operational directorate's 
ongoing effort to review all IETF documents being processed by the IESG.  These 
comments were written with the intent of improving the operational aspects of the 
IETF drafts. Comments that are not addressed in last call may be included in AD reviews 
during the IESG review.  Document editors and WG chairs should treat these comments 
just like any other last call comments. 

Summary: This document recommends deprecation of the use of Any-Source Multicast (ASM) for interdomain multicast, and instead it recommends the use of Source-Specific Multicast (SSM).

From an Operations perspective, deployment is discussed throughout the document. This is important. The proposed specification recommends the deprecation of ASM and as such it brings network simplification and cuts down on technical debt. Specifically, Section 3 greatly discusses deployment trade-offs and comparisons.

In regards to configuration, it is allso very well covered in Section 3.1, and the net of it is that configuration complexity is removed in the recommended deployments.

Finally, Section 4.9 includes migration considerations. All in all, I believe all major operational considerations are adequately covered.

Should the reference for RFC8313 be Normative instead of Informative?



   This document recommends deprecation of the use of Any-Source
   Multicast (ASM) for interdomain multicast.  It recommends the use of
   Source-Specific Multicast (SSM) for interdomain multicast
   applications and that hosts and routers in these deployments fully
   support SSM.

CMP: Typo? "and that" does not seem sensible.
