Summary: This document is technically solid and aligns well with existing MPLS
and SR OAM mechanisms.

Some Nits though:

Abstract: “via a controller-based mechanisms” → remove plural: “via a
controller-based mechanism”

Section 3.1: “The appropriate respond is sent back…” → should be: “The
appropriate response is sent back…”

Section 6 (Security): “Overall, the security needs for P2MP policy ping is same
as [RFC8029].”  — grammatical fix: “...are the same as...”

Section 5 (IANA): “This sub-type value is assigned from the standards Action of
range...”   — is it better with : “...from the Standards Action range of ...”

The following sentence is difficult to follow (Section 3.1.3):
"For example, when a P2MP Policy Ping or Traceroute packet enters an Unicast SR
domain, it MUST be processed on the two interconnecting Replication Segments,
based on the Replication SID and its TTL value.".
