# Document Shepherd Write-Up for Group Documents
## 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?
The document has broad consensus in the working group. It has been developed
over a number of years and addresses part of an OAM milestone.
2. Was there controversy about particular points, or were there decisions where
the consensus was particularly rough?
This document was not controversial.
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.)
None indicated.
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
(where)?
None indicated. There are numerous known implementations of OAM over tunnels
e.g. MPLS LSPs, and there are known implementations of Geneve (RFC8926).
Although there is no formal record of implementations of active OAM over
Geneve, this draft does not make any changes to OAM state machines or protocols
themselves, and simply describes how they should be encapsulated.
## Additional Reviews
5. Do the contents of this document closely interact with technologies in other
IETF working groups or external organizations, and would it therefore benefit
from their review? Have those reviews occurred? If yes, describe which
reviews took place.
The draft was subject to a RTG DIR early review, which concluded that it was
ready. It was also reviewed by the GenART team and was considered ready.
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.
There are no requirements for formal expert review.
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 module specififed.
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.
The document contains no formal languages.
## 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 have reviewed the document and provided a number of comments to improve
the readability of the document, all of which were addressed. I believe it is
ready to be handed off to the IESG.
10. Several IETF Areas have assembled [lists of common issues that their
reviewers encounter][6]. For which areas have such issues been identified
and addressed? For which does this still need to happen in subsequent
reviews?
No issues identified.
11. What type of RFC publication is being requested on the IETF stream ([Best
Current Practice][12], [Proposed Standard, Internet Standard][13],
[Informational, Experimental or Historic][14])? Why is this the proper type
of RFC? Do all Datatracker state attributes correctly reflect this intent?
Standards Track. This is appropriate as the draft specifies an encapsulation
method for OAM for NVO3 networks using Geneve (RFC8926).
12. Have reasonable efforts been made to remind all authors of the intellectual
property rights (IPR) disclosure obligations described in [BCP 79][7]? To
the best of your knowledge, have all required disclosures been filed? If
not, explain why. If yes, summarize any relevant discussion, including links
to publicly-available messages when applicable.
Yes. Requests for IPR declarations, or knowledge of applicable IPR, were made
at WG adoption and last call time. There are no IPR disclosures and all authors
and contributors have indicated that they are not aware of any applicable IPR.
13. Has each author, editor, and contributor shown their willingness to be
listed as such? If the total number of authors and editors on the front page
is greater than five, please provide a justification.
Yes. There are four authors listed.
14. Document any remaining I-D nits in this document. Simply running the [idnits
tool][8] is not enough; please review the ["Content Guidelines" on
authors.ietf.org][15]. (Also note that the current idnits tool generates
some incorrect warnings; a rewrite is underway.)
ID-Nits passes. There is one warning about an IPv4 address format. This seems
to be triggered by a reference to an IPv4 loopback address in the document
(127.0.0.1/32), but that looks OK.
15. Should any informative references be normative or vice-versa? See the [IESG
Statement on Normative and Informative References][16].
The references appear to be classified correctly.
16. List any normative references that are not freely available to anyone. Did
the community have sufficient access to review any such normative
references?
All normative references are to RFCs.
17. Are there any normative downward references (see [RFC 3967][9] and [BCP
97][10]) that are not already listed in the [DOWNREF registry][17]? If so,
list them.
No normative down-refs.
18. Are there normative references to documents that are not ready to be
submitted to the IESG for publication or are otherwise in an unclear state?
If so, what is the plan for their completion?
All normative references are to published RFCs.
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.
No.
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][11]).
There are no IANA requests.
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.
There are no IANA requests.
