As required by RFC 4858, this is the current template for the Document
Shepherd Write-Up. Changes are expected over time.
This version is dated 1 November 2019.
(1) What type of RFC is being requested (BCP, Proposed Standard, Internet
Standard, Informational, Experimental, or Historic)? Why is this the proper
type of RFC? Is this type of RFC indicated in the title page header?
The document is standard track and it is the appropriate type as the document
defines protocol extensions.
(2) The IESG approval announcement includes a Document Announcement Write-Up.
Please provide such a Document Announcement Write-Up. Recent examples can be
found in the "Action" announcements for approved documents. The approval
announcement contains the following sections:
This draft specifies new procedures that allow inter-subnet IP
multicast traffic to be routed among the LANs of a given tenant,
while still making intra-subnet IP multicast traffic appear to be
Working Group Summary:
Draft have been discussed in different IETF meetings and good amount of
discussion in working group mailing list as well. It has consensus in he WG.
Document has been written very well and clearly mentions each of the procedure.
Who is the Document Shepherd? Who is the Responsible Area Director?
Mankamana Mishra is Document Shepherd
Martin Vigoureux is the responsible AD
(3) Briefly describe the review of this document that was performed by the
Document Shepherd. If this version of the document is not ready for

is ready for publication.
(4) Does the document Shepherd have any concerns about the depth or breadth of
the reviews that have been performed? No
(5) Do portions of the document need review from a particular or from broader
perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or
internationalization? If so, describe the review that took place. No
(6) Describe any specific concerns or issues that the Document Shepherd has
with this document that the Responsible Area Director and/or the IESG should be
aware of? For example, perhaps he or she is uncomfortable with certain parts of
the document, or has concerns whether there really is a need for it. In any
event, if the WG has discussed those issues and has indicated that it still

WG as a whole understand and agree with it? There is a solid consensus and it s
involving multiple vendors and operators.
(10) Has anyone threatened an appeal or otherwise indicated extreme discontent?
If so, please summarise 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
(11) Identify any ID nits the Document Shepherd has found in this document.
(See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist).
Boilerplate checks are not enough; this check needs to be thorough.
(12) Describe how the document meets any required formal review criteria, such
as the MIB Doctor, YANG Doctor, media type, and URI type reviews. Not applicable
(13) Have all references within this document been identified as either
normative or informative? Yes
(14) Are there normative references to documents that are not ready for
advancement or are otherwise in an unclear state? If such normative references

list these downward references to support the Area Director in the Last Call
(16) Will publication of this document change the status of any existing RFCs?
Are those RFCs listed on the title page header, listed in the abstract, and
discussed in the introduction? If the RFCs are not listed in the Abstract and
Introduction, explain why, and point to the part of the document where the
relationship of this document to the other RFCs is discussed. If this

to validate sections of the document written in a formal language, such as XML
code, BNF rules, MIB definitions, YANG modules, etc.
(20) If the document contains a YANG module, has the module been checked with
any of the recommended validation tools
(https://trac.ietf.org/trac/ops/wiki/yang-review-tools) 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
