Review in context: https://mozphab-ietf.devsvcdev.mozaws.net/D3642

A diagram in the introduction would have helped me.


            Grained Label [RFC7172]. By implication, an "FGL TRILL
            switch" does not support MT.
You are using MT before expansion here. But I actually don't understand why it does not. Can you explain?



            implication, a "VL RBridge" or "VL TRILL switch" does not
            support FGL or MT.
My same question here as above. Why can't a VL TRILL switch support MT?



  (1) all TRILL switch ports on the link advertise topology T support
      in their Hellos and
  (2) if any TRILL switch port on the link requires explicit TRILL Data
Probably stupid question but how do you know that there aren't TRILL switches that you haven't heard from yet that don't support T?



    V -  The version number of the MT label. This document specifies
        version zero.
What do I do if I receive an unknown version?



        +  There may be non-zero topologies with no multi-destination
            traffic or, as descried in [RFC5120], even topologies with
            no traffic at all. For example, if only known destination
Nit: described



            topology, there would be no need for a distribution tree for
            topology T.  For this reasons, a Number of Trees to Compute
            of zero in the Trees sub-TLV for the TRILL switch holding
Nit: "reason"

[Ballot comment]
The extensions defined in this document are "an optional TRILL switch capability".  To me, that indicates that the base TRILL specifications rfc6325 and rfc7177 (in this case) are not affected: an RBridge is TRILL-compliant as long as it implements what rfc6325 specifies (without these optional extensions).  I would then like to see the formal "Updates" tags removed.

[The publication of this document is not the place to argue about the meaning of "Updates", so I'll defer to what the Responsible AD decides.]

(Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs:

The IANA Services Operator has completed its review of draft-ietf-trill-multi-topology-05. If any part of this review is inaccurate, please let us know.

The IANA Services Operator understands that, upon approval of this document, there is a single action which we must complete.

In the PORT-TRILL-VER Sub-TLV Capability Flags regsitry on the Transparent Interconnection of Lots of Links (TRILL) Parameters registry page located at:

https://www.iana.org/assignments/trill-parameters/

a single registration consisting of two adjacent bits will be made as follows:

Bit: [ TBD-at-Registration ] and [ TBD-at-Registration ]
Description: Topology labeling support
Reference: [ RFC-to-be ]

We understand that these two bits are to be adjacent and from the bits available between 14 and 31. IANA also notes that the authors suggest bits 14 and 15 for this assignment.

The IANA Services Operator understands that this is the only action required to be completed upon approval of this document.

Note:  The actions requested in this document will not be completed until the document has been approved for publication as an RFC. This message is meant only to confirm the list of actions that will be performed.

Please note that specific values cannot be reserved. However, early allocation is available for some types of registrations. For more information, please see RFC 7120.

Technical Summary

Abstract
  This document specifies extensions to the IETF TRILL (Transparent
  Interconnection of Lots of Links) protocol to support multi-topology
  routing of unicast and multi-destination traffic based on IS-IS
  (Intermediate System to Intermediate System) multi-topology specified
  in RFC 5120. This document updates RFC 6325 and RFC 7177.

Working Group Summary

Strong Consensus as part of the solution for
WG milestones on multiple topology.

TRILL works differently than other WGs.
It has brought up lots of drafts, and had deep engineering
discussions at IETF.  The engineers go off and debate the
topics one-on-one or individually. 
The depth of the engineering clue is high (e.g. Radia
Perlman,  Donald Eastlake, Jon Hudson, Mingui Zhang,
Ayan Banerjee, and others.  The WG simply does not
waste time on fights or much email. 
So.. IESG, if you are looking for the email trail.
It just is not going to be there - as you expect.
If you look for engineering quality in this draft,
you will find it.

Document Quality
Engineering on Technology good.
Document has been through strong editing by
main author to remove "engineering-english".

Donald Eastlake has been an editor for
IEEE documents, you will find this influnces his style.
IESG - Please consider your review whether you are
complaining about style or substance.

Personnel

Shepherd: Susan Hares
AD:  Alia Atlas
RTG-DIR early reviewer: Martin Vigoureux


(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) Nits
b) Review RTG-DIR reviewer
only substantive concern was one definition:  MT TRILL Switch\
c) 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. 

(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? 

None.

(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. If not, explain why.

(8) Has an IPR disclosure been filed that references this document?
If so, summarize any WG discussion and conclusion regarding the IPR
disclosures.

No IPR disclosures

(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? 

Solid.  Again, the IESG will have trouble with the lack of substantive debate
during the last year.  The TRILL WG took on several key pieces of work
(directory services, multi-topology enhancements, group key security).
This working group has a solid engineering approach were we went off
did a bunch of drafts, discussed at IETF meetings the options and
went back and refined the documents.  The issues in the multiple topologies
are complex, but well know to the authors who come from
two vendors that deployed early TRILL work.

Again, the solution was debated and the draft approach set-up.
Then, individuals took on writing the drafts and getting feedback.
The result is a solid document - but little email.

Just warning you, it is not there. 
TRILL has solid engineering by quiet individuals
goes against the list debate style.


(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.)

Nope - see comments in #9.

(11) Identify any ID nits the Document Shepherd has found in this
document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be
thorough.

Again.  Two things are nitted - the fact the authors had this ready for
the shepherd and it has sat behind other drafts.
(mia culpa)
  [IS-IS] - ISO/IEC 10589:2002 - is correctly stated, but the NITS wonders. 
(sigh.. )

(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.

None. 
Security considerations are brief, but RFC6325 is there.
If group keys are part of concern, see the protocol independent solution.
draft-ietf-trill-group-keying-01

We suggest that the Security Dispatch group take it over, and the
routing can provide a provide (draft-ietf-trill-link-gk-profiles-00) to the rtgwg.
TRILL has engineered a solution, but we will need to have
security area review. 

(13) Have all references within this document been identified as
either normative or informative?

Yes - 
Please note that ISIS (ISO10589) sometimes gives the NITS program fits.
It is correct, but NITS complains.  (sigh)

(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

(15) Are there downward normative references references (see RFC 3967)?
If so, list these downward references to support the Area Director in
the Last Call procedure.

no.

(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? 
Updates: RFC6325, RFC 7177

RFCs in header, abstract, and introduction.

(17) Describe the Document Shepherd's review of the IANA considerations
section, especially with regard to its consistency with the body of the
document. 

IANA section requests:
1) the IEEE Registration Authority will be requested to allocate a new
  Ethertype for the MT label

2) assign two adjacent bits (TBD) from
  bits 14 through 31 of the Capabilities bits of the Port TRILL Version
  Sub-TLV for the Explicit Topology capability field and update the
  "PORT-TRILL-VER Capability Bits" registry as follows

(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.

None.

(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.

none
