[Teas] Re: Second Working group last call of draft-ietf-teas-rfc8776-update-13 - one week

[[e-mail]]

Hi Italo, all,

1- You may use the updated security template in the 8407bis. With that, even NETCONF/RESTCONF can be moved to informative. See the full guidance in the bis.
2- I also noticed some issues in the tree for list keys. These are displayed as optional!
This is actually a pyang bug. I checked RFC8776, but see that the too long tree was not included.

Adrian, Med,

Thanks for your feedbacks

We have updated the draft to address the nits as discussed on the mailing list and we plan to submit it as soon as the submission reopens

You can have a preview at this link:

https://raw.githubusercontent.com/italobusi/te/refs/heads/8776-bis-2nd-wg-lc/drafts/te-types-update/draft-ietf-teas-rfc8776-update.txt

Please review the proposed changes and let us know if you any other comments before we submit the updated I-D

Thanks, Italo (on behalf of co-authors/contributors)

Hi Italo,

I don't have the context that led to the text you quoted, but the key message out there is "normative reference statement". Not every cited document listed in a ref stmt is normative.

We need to avoid creating clusters in the publication process that would delay publication and would be a nightmare for every one.

My advice is to tweak the description so that the ref is only informative. Thanks.

Cheers,
Med

Hi Med,

I am getting a bit confused about the requirements in RFC 8407

How would you suggest to reconcile this with the following text in section 3.9 of RFC 8407 (and of RFC 8407-bis)?

For every normative reference statement that appears in a module contained in the specification that identifies a separate document, a corresponding normative reference to that document SHOULD appear in the Normative References section. The reference SHOULD correspond to the specific document version actually used within the specification.

It is not clear to my why this is a SHOULD and not a MUST and therefore under which circumstance we can deviate from the SHOULD

Thanks, Italo

Hi all,

For the first point below, as this one is still in the WG state and it is not used in an import, I think that it is better to follow this part from 8407 and move that I-D to be listed as informative:

      Be sure citations for all imported modules are present somewhere
      in the document text (outside the YANG module).  If a YANG module
      contains reference or "description" statements that refer to an
      I-D, then the I-D is included as an informative reference.

Cheers,
Med

Thanks for the opportunity, Oscar.

I always look at idnits. I see that it is warning about a lot of downrefs. Downrefs aren't necessarily a bad thing, but there really are a lot here, and it made me wonder.
So...

  *   Does this document really need to be gated by draft-ietf-pce-sid-algo which is currently only 4th in the queue for WGLC in PCE?
  *   Do we really need normative references to such a long list of Informational RFCs?
  *   RFC 4115 seems like a *really* bad thing to include as a normative reference from an IETF standards track RFC given that it is an Independent Stream publication with a fairly assertive IESG note.
  *   RFCs 4125 and 4126 are a bit shaky as normative references. I'm not sure what the status of the experiments described is. Certainly, no one thought it worth moving them on to the Standards Track.
  *   RFC 4427 is a fine document, and explains a lot of stuff. But I don't think it defines any process or protocol behaviour. So does a normative reference actually give it too much weight? Should we be using the RFCs that actually define the different recovery protocol behaviours? For example:
     identity clear {
       base protection-external-commands;
       description
         "An action that clears the active near-end lockout of a
          protection, forced switchover, manual switchover, WTR state,
          or exercise command.";
       reference
         "RFC 4427: Recovery (Protection and Restoration) Terminology
                    for Generalized Multi-Protocol Label Switching
                    (GMPLS)";
     }
The term "WTR" or "WTR state" is not found in RFC 4427, although "Wait To Restore time" is in 4.16.
On the other hand, "Wait-To-Restore (WTR)" is in 6.1 of RFC 4428 and 6.2 has "a local Wait-to-Restore (WTR) state". Mind you, 4428 is also Informational.
RFC 6378 begins to put some behavioural substance behind the concept of a WTR timer, and the state machine has a WTR State.

  *
I'm not going to go through all of the references and check them. It is possible that some downrefs are a good idea (and will need to be called out in the shepherd write-up and the IETF last call unless they are already in the downref registry). The authors might want to check carefully.

Otherwise, this looks like a solid (if rather large) piece of work. Well done to the authors!

I think that the Security Considerations given here are correct. This is the equivalent of a family of typedefs. Of themselves, there is no security risk. It all depends how other YANG modules use them.

Cheers,

Adrian

Subject: [Teas] Second Working group last call of draft-ietf-teas-rfc8776-update-13 - one week

Dear TEAS WG colleagues,

       As a result of the comments during the WG LC of draft-ietf-teas-rfc8776-update-10, the authors made several changes. The current version is draft-ietf-teas-rfc8776-update-13.

      This email starts a second working group last call on https://datatracker.ietf.org/doc/draft-ietf-teas-rfc8776-update/.

    As the focus is on the changes from -10 to -13, the duration will be one week. Hence, the second working group last call ends on October 18th 2024.

    Please send your comments to the working group mailing list. To facilitate the review, please find the diff here: Diff: draft-ietf-teas-rfc8776-update-10.txt - draft-ietf-teas-rfc8776-update-13.txt<https://author-tools.ietf.org/iddiff?url1=draft-ietf-teas-rfc8776-update-10&url2=draft-ietf-teas-rfc8776-update-13&difftype=--html>

Thank you,
              Oscar
