I have started a working copy of the document, and will post when Deborah tell me.

A recent IESG queried whether or not IANA could be a Normative Reference; this I-D makes me hope that that question is resolved.


Yes, we resolved this and the SPL terminology was approved by the IESG and the comment from Murray Kucherawy was withdrawn.

Abstract LSP needs expanding, not a starred abbreviation

Fixed this.

Question: Do you think the document title also need to be updated?

RSC, DDMAP later, likewise

hmmm, this might be a can of wors, with quite substantial ripple effects. But it you insist I can open it :).

The registry is defined in RFC 8029 with <RFC> (no expansion in it).

The <RSC> is in a part of the registry that isd not changed by this document, and there is a clear reference to RFC 8029 where it is expanded, so if I don't expand in the registry that in the registry that would be an update to RFC 8029 . Doable! But the update/expansion would be in a section where RSC (Return Subcode) is already expanded and the text of RFC 8029 would flow badly.

There is one more thing that is not intended as a chage, the draft says (RSC), but the registry says <RSC>, I have been looing for how to enter < and > into xml, but not found it, can someone help?

I'm inclined to not expand <RSC> in the registry, maybe we could add a note after the registry with the expansion and referencing the correct paragraph in RFC 8029, section 3.1.

DDMAP is the same thing, it is correctly expanded in RFC 8029m which if referenced. This is also a part of the registry that has not been changed.



sun-TLVs appears 37 times; perhaps sub-TLVs

fixed

/[[RFC8209]/[RFC8209]/

fixed


/Loa

3.1.1
'will be sent' perhaps MUST be

'may be silently ignored' perhaps MAY

I would like a second opinion on this, I think this is rather description than specification.


6.1.3
'AM Problem/Delay' OAM?

fixed

/Loa

Abstract


    This document updates RFC 8029 and RFC 8611 that both define IANA
    registries for MPLS LSP Ping.  It also updates the description of the
    procedures for the responses sent when an unknown or erroneous code
    point is found.  The updates are to clarify and align this name space
    with recent developments.

No IPR declarations have been submitted directly on this I-D.
