Section 16, Normative References:

1238 >               9798bis-01, 14 March 2026,

This is a normative reference to draft-ietf-pim-rfc8059-9798bis-01,
which is the specification this document actually depends on for the
PIM Join/Prune attributes it uses:

414 >        [I-D.ietf-pim-rfc8059-9798bis]; this document specifies no
415 >        additional state machinery.

653 >    specified in [I-D.ietf-pim-rfc8059-9798bis].

draft-ietf-pim-rfc8059-9798bis-01 expired in March 2026. There's
currently no path to publication for it.

The history here is worth spelling out, because I think it points to
an easy fix. Through -06, this document cited RFC 8059 and RFC 9798
directly for these attributes. Darren Dukes' RTGDIR review asked
whether those two should be normative or informative references. The
author's reply on the list was, in effect, that the question was moot
because both were being folded into a single reference to
draft-ietf-pim-rfc8059-9798bis, and that's what shipped in -08. Having
now read that bis draft, I don't think the trade was a good one: it's
a pure consolidation of RFC 8059 and RFC 9798 (it just moves the
Transport Attribute and Receiver RLOC Attribute registrations into one
document) and doesn't define anything new that this document actually
relies on. So the change that answered Darren's question left the
document with an unresolved dependency in its place.

I'd ask the authors to revert Section 4 item 8 and Section 7.1 to
citing RFC 8059 and RFC 9798 directly, and drop the reference to the
bis draft. That does bring Darren's original question back: RFC 8059
and RFC 9798 are Experimental, and this document targets Proposed
Standard, so citing them normatively is a downref. But that's a
well-understood problem with a known process.

I'd also note the shepherd write-up (answering as of -06) states there
are no normative references in an unclear state. That was accurate
when written; the -07/-08 revision changed that, and it's worth a
fresh look before this goes further.

COMMENT:
----------------------------------------------------------------------

Section 17, Informative References, still carries a second, uncited
entry for the same draft:

1314 >    [draft-ietf-pim-rfc8059-9798bis]
1315 >               Govindan, V. and S. Venaas, "PIM Join Attributes for
1316 >               Locator/ID Separation Protocol (LISP) Environments", Work
1317 >               in Progress, Internet-Draft, draft-ietf-pim-rfc8059-
1318 >               9798bis-01, 14 March 2026,

Nothing in the body cites this anchor - both in-text uses I found
(Section 4 item 8 and Section 7.1) use [I-D.ietf-pim-rfc8059-9798bis],
which is the normative entry. This looks like debris from the same
edit that produced my DISCUSS.

Building on Ketan's DISCUSS-2 about the unicast receiving procedure,
the normative text in Section 8.3.2 has a scope problem:

811 >    When using a unicast underlay, an ETR MUST accept a unicast LISP-
812 >    encapsulated multicast packet only where the outer destination
813 >    address is one of its own RLOCs.  Additionally, it MAY check whether
814 >    the outer source address is the ITR RLOC it selected for the
815 >    (S-EID,G) in question.  It MUST discard the packet otherwise.

"Otherwise" is ambiguous between the two preceding sentences. If it
only refers back to the destination-address MUST, the optional source
check in the middle sentence is pointless - there's no discard
obligation tied to failing it. If it's meant to cover a failed source
check too, that needs to be MUST-level for a conforming implementation
to know what to do when it chooses to perform the check at all.

All comments below are about very minor potential issues that you may
choose to address in some way - or ignore - as you see fit. Some were
flagged by automated tools (via
https://github.com/larseggert/ietf-reviewtool), so there will likely
be some false positives. There is no need to let me know what you did
with these suggestions.
