Shepherd writeup

# Document Shepherd Writeup

*This version is dated 8 April 2022.*

Thank you for your service as a document shepherd. Among the responsibilities is
answering the questions in this writeup to give helpful context to Last Call and
Internet Engineering Steering Group ([IESG][1]) reviewers, and your diligence in
completing it, is appreciated. The full role of the shepherd is further
described in [RFC 4858][2], and informally. You will need the cooperation of
authors to complete these checks.

Note that some numbered items contain multiple related questions; please be sure
to answer all of them.

## Document History

1. Does the working group (WG) consensus represent the strong concurrence of a
   few individuals, with others being silent, or did it reach broad agreement?

This is small bis update we took through the WG quickly. It had clear
consensus, with 
about 1/3-1/2 of the active WG chiming in. Both RFC8321bis and
RFC8889bis are being taken through the process together.

2. Was there controversy about particular points, or were there decisions where
   the consensus was particularly rough?

There was no controversy in these updates within the WG.

3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If
   so, please summarize the areas of conflict in separate email messages to the
   responsible Area Director. (It should be in a separate email because this
   questionnaire is publicly available.)

No appeals threatened.

4. For protocol documents, are there existing implementations of the contents of
   the document? Have a significant number of potential implementers indicated
   plans to implement? Are any existing implementations reported somewhere,
   either in the document itself (as [RFC 7942][3] recommends) or elsewhere

Our adoption call of the -bis document raised the question of implementations,
and several implementations were discussed on the mailing list.

### Additional Reviews

5. Does this document need review from other IETF working groups or external
   organizations? Have those reviews occurred?

This -bis effort was spurred on by draft-ietf-6man-ipv6-alt-mark, which
normatively references the work. Authors are participants of both WGs, and that
WG is aware of this work.

6. Describe how the document meets any required formal expert review criteria,
   such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.

No formal review needed.

7. If the document contains a YANG module, has the final version of the module
   been checked with any of the [recommended validation tools][4] for syntax and
   formatting validation? If there are any resulting errors or warnings, what is
   the justification for not fixing them at this time? Does the YANG module
   comply with the Network Management Datastore Architecture (NMDA) as specified
   in [RFC 8342][5]?

No YANG model.

8. Describe reviews and automated checks performed to validate sections of the
   final version of the document written in a formal language, such as XML code,
   BNF rules, MIB definitions, CBOR's CDDL, etc.

Not applicable.

### Document Shepherd Checks

9. Based on the shepherd's review of the document, is it their opinion that this
   document is needed, clearly written, complete, correctly designed, and ready
   to be handed off to the responsible Area Director?

Yes, I think these documents are ready to progress.

10. Several IETF Areas have assembled [lists of common issues that their
    reviewers encounter][6]. Do any such issues remain that would merit specific
    attention from subsequent reviews?

I do not believe this document requires further area reviews.

11. What type of RFC publication is being requested on the IETF stream (Best
    Current Practice, Proposed Standard, Internet Standard, Informational,
    Experimental, or Historic)? Why is this the proper type of RFC? Do all
    Datatracker state attributes correctly reflect this intent?

Proposed Standard. The point of this bis effort is to move from Experimental
to Proposed Standard.

12. Has the interested community confirmed that any and all appropriate IPR
    disclosures required by [BCP 78][7] and [BCP 79][8] have been filed? If not,
    explain why. If yes, summarize any discussion and conclusion regarding the
    intellectual property rights (IPR) disclosures, including links to relevant

Yes, IPR is filed for both RFC8321bis and RFC8889bis, which is just a carry-over
of the existing IPR on the original RFC8321 and RFC8889 documents.

13. Has each Author or Contributor confirmed their willingness to be listed as
    such? If the number of Authors/Editors on the front page is greater than 5,
    please provide a justification.

Both documents have 5 authors each, and all authors were involved with the
original RFCs.

14. Identify any remaining I-D nits in this document. (See [the idnits tool][9]
    and the checkbox items found in Guidelines to Authors of Internet-Drafts).
    Simply running the idnits tool is not enough; please review the entire
    guidelines document.

Nits for RFC8321bis:

  ** The abstract seems to contain references ([RFC8321]), which it
     shouldn't.  Please replace those with straight textual mentions of the
     documents in question.

  -- Possible downref: Non-RFC (?) normative reference: ref. 'IEEE-1588'

These items should be addressed by making the reference to RFC8321 in the
abstract textual as suggesting, making the reference to IEEE-1588 informative.

15. Should any informative references be normative or vice-versa?

For RFC8321bis: the reference to IEEE-1588 might need to become informative.

16. List any normative references that are not freely available to anyone. Did
    the community have sufficient access to review any such normative

All references are available.

17. Are there any normative downward references (see [RFC 3967][10],
    [BCP 97][11])? If so, list them.

See note above about IEEE-1588.

18. Are there normative references to documents that are not ready for
    advancement or are otherwise in an unclear state? If they exist, what is the
    plan for their completion?


19. Will publication of this document change the status of any existing RFCs? If
    so, does the Datatracker metadata correctly reflect this and are those RFCs
    listed on the title page, in the abstract, and discussed in the
    introduction? If not, explain why and point to the part of the document
    where the relationship of this document to these other RFCs is discussed.

Yes, RFC8321bis obsoletes RFC8321, as described in the abstract.

20. Describe the document shepherd's review of the IANA considerations section,
    especially with regard to its consistency with the body of the document.
    Confirm that all aspects of the document requiring IANA assignments are
    associated with the appropriate reservations in IANA registries. Confirm
    that any referenced IANA registries have been clearly identified. Confirm
    that each newly created IANA registry specifies its initial contents,
    allocations procedures, and a reasonable name (see [RFC 8126][12]).

This document does not have IANA actions.

21. List any new IANA registries that require Designated Expert Review for
    future allocations. Are the instructions to the Designated Expert clear?
    Please include suggestions of designated experts, if appropriate.

This document does not have IANA actions.
