[Last-Call] Re: Rtgdir last call review of draft-ietf-opsawg-ntw-attachment-circuit-12

Thank you Med.

On the issue of References, the tree diagram, and nesting.  One example.  grouping attachment-circuit-reference in section 5.2 lists three children, ac-ref2, node-ref2, and network-ref2.

However, the actual yang for attachment-circuit-reference has one leaf, ac-ref, with type leafref, and a path.  If I follow that path, I will find a leaf node-ref, with a path, which in turn points to a network-ref.   Thus, in the YANG, it is what I would describe as nested, which is not the same as the tree diagram.  I don't know that it matters, but I found it confusing.

Yours,

Joel

Objet : Rtgdir last call review of draft-ietf-opsawg-ntw-
attachment-circuit-12

Reviewer: Joel Halpern
Review result: Ready

Hello,

I have been selected as the Routing Directorate reviewer for this
draft. The Routing Directorate seeks to review all routing or
routing-related drafts as they pass through IETF last call and
IESG review, and sometimes on special request. The purpose of the
review is to provide assistance to the Routing ADs.

Although these comments are primarily for the use of the Routing
ADs, it would be helpful if you could consider them along with
any other IETF Last Call comments that you receive, and strive to
resolve them through discussion or by updating the draft.

Summary:
Choose from this list...

No issues found. This document is ready for publication.
     I have a few minor comments that should be considered.

This is a truly impressive piece of work.  The editors have
pulled together information from a myriad sources into a usable
(if massive) YANG module that addresses the range of needs very
well.
[Med] Glad to hear that.

Major Issues: N/A

Minor Issues:
     I note that section 5.1 in discussing parent relationships
specifies that
     if a parent AC is deleted, all the child ACs MUST be deleted.
Given that
     there is no reference from a parent to its children (unless I
missed it),
     it seems to this reader that it would really help
implementors to tell them
     how this is to be done?  Are all children to be delted first,
and the
     client give an error if there are any active children?  Is
the client to
     silently find and delete all ACs which point to the deleted
AC as a parent?
      Or some other means?
[Med] Good point. Updated the model so that a parent AC can maintain references to its child ACs. The tree structure is updated with the following:

NEW:
      +--ro ac-child-ref
      |  +--ro ac-ref*        leafref
      |  +--ro node-ref?      leafref
      |  +--ro network-ref?   -> /nw:networks/network/network-id

Added also a sentence to refer to that in the narrative text.

Thanks for catching this.

    In section 5.2 (References) in describing the groupings the
tree diagram
    shows a number of peer entities.  However, unless I am
misreading the YANG,
    they are, in almost all cases, actually nested.  Was this a
deliberate
    simplification, on artifact of the tree generation tool, or an
error in my
    reading?
[Med] I'm not sure to get the point (especially, the "peer entities"). These groupings are actually independent but are grouped in the same figure for convenience.

     I note that the document refers to RIP in multiple places.
Unless I missed
     something, this references RIPv2, but not RIPng (RFC 20808).
I can imagine
     reasons for such an omission.  If there is a good reason,
then please state
     it.  Otherwise, sorry, please also cover 2080.

[Med] We do cite 2080 in 5.6.5.

I suspect that you were referring to the module itself. Updated it accordingly.
