Date of Shepherd review: 2/18/2018
(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?
Informational as noted on the title page. This document does not
change any existing standard.
(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:
Technical Summary:
This document specifies methods to interconnect multiple Transparent
Interconnection of Lots of links (TRILL) sites with an intervening
MPLS network using existing TRILL and VPLS standards. This draft
addresses two problems as follows:
1) Providing connection between more than two TRILL sites that are
separated by an MPLS provider network.
2) Providing a single logical virtualized TRILL network for different
tenants that are separated by an MPLS provider network.
Working Group Summary:
Was there anything in WG process that is worth noting? For example,
was there controversy about particular points or were there decisions
where the consensus was particularly rough?
Document Quality:
Are there existing implementations of the protocol? Have a significant
number of vendors indicated their plan to implement the specification?
Are there any reviewers that merit special mention as having done a
thorough review, e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If there was a
MIB Doctor, Media Type or other expert review, what was its course
(briefly)? In the case of a Media Type review, on what date was the
request posted?
Personnel:
Document Shepherd: Susan Hares
Responsible Area Director: Alia Atlas
(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 publication, please explain why the document is being
forwarded to the IESG.
a) requested and resolved 2 target reviews by MPLS related chairs
(Loa Anderson and Andy Mallis)
b) ID Nits
c) deep dive of technology in early days
d) review of final document.
(4) Does the document Shepherd have any concerns about the depth or
breadth of the reviews that have been performed?
No. It just doesn't get any better than to get the MPLS gurus
(Loa Anderson, Andy Mallis, and Matthew Bocci) to
reviewed this draft and suggest changes.
(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.
The draft was reviewed by Any Malis who is knowledgeable in MPLS and
his comments were resolved:

(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 wishes to advance the document, detail those concerns here.
No.
(7) Has each author confirmed that any and all appropriate IPR
disclosures required for full conformance with the provisions of
BCP 78 and BCP 79 have already been filed.
Yes:

Kingston Smiler Selvaraj

(8) Has an IPR disclosure been filed that references this document?
No.
(9) How solid is the WG consensus behind this document? Does it
represent the strong concurrence of a few individuals, with
others being silent, or does the WG as a whole understand and
agree with it?
Vendors in the WG (Huawei, IP Infusion, and others) wanted to have
this informational draft in order to provide wisdom for customers.
This draft provides a clear explanation for these customers on how
to link two campuses via an MPLS provider network.
TRILL deployments in Europe and Asia (Japan and India)
originally asked for this type of insight.
(10) Has anyone threatened an appeal or otherwise indicated extreme
discontent?
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.
None.
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type
reviews.
No such formal review required.
(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 exist, what is the plan for their
completion?
No. Nits indicates things are fine.
Please note this draft references the original ISO ISIS specification
(ISO10589). This is valid, but sometimes the NITS will complain.
(15) Are there downward normative references references (see RFC
3967)?
No.
(16) Will publication of this document change the status of any
existing RFCs?
This document does not change the status of any existing RFC.
(17) Describe the Document Shepherd's review of the IANA
considerations section, especially with regard to its consistency
with the body of the document.
This document requires no IANA actions.
(18) List any new IANA registries that require Expert Review for
future allocations. Provide any public guidance that the IESG
would find useful in selecting the IANA Experts for these new
registries.
This document creates nonew registries.
(19) Describe reviews and automated checks performed by the Document
Shepherd to validate sections of the document written in a formal
language, such as XML code, BNF rules, MIB definitions, etc.
There are no such sections.
