[MBONED]Re: [iesg] Mike Bishop's No Objection on for: (with COMMENT)

Hi Mike,

Thank you for confirming.

The clarification I provided is really the reason why this is not reused.

For full context, I have asked the authors during my AD review to check if we can reused the grouping and if not document the rationale in the draft, hence the design note.

Cheers,
Med

Yes, that was the one. I was surprised a constraint couldn't be placed to use the existing grouping, but restrict it to IP addresses rather than hostnames. If not, that's fine.

Subject: RE: [iesg] Mike Bishop's No Objection on for: (with COMMENT)

Hi Mahesh,

My reading of Mike's comment is that he was referring to "Section 4.2.2, paragraph 13", which seems to me to be this part:

CURRENT:
      Design note: The four data nodes ('gateway-address', 'gateway-
      port', 'local-address', and 'local-port) do not reuse the standard
      "udp-client" grouping defined in
      [I-D.ietf-netconf-udp-client-server] because AMT requires the
      Gateway to be a specific IP address (inet:ip-address), while the
      "udp-client" grouping allows the use of domain names (inet:host).
      Reuse could lead to configuration errors or runtime risks, so a
      custom structure must be defined to enforce this constraint.

Hence, grouping, refine, etc.

Mike, can you please explicit the part you were referring to?

Cheers,
Med

Section 4.2.2, paragraph 13

Forgive my lack of YANG expertise, but doesn't YANG support
constraints
to further restrain what values are acceptable? Would a "must" not
have worked
here rather than creating a more constrained type?

[Med] YANG supports some means to constrain data types (when, must, range, etc.). However, there are only a subset of possibilities when it comes to refining a reused grouping (see https://datatracker.ietf.org/doc/html/rfc7950#section-7.13.2 or https://datatracker.ietf.org/doc/html/rfc9907#name-yang-data-node-constraints) This is actually why some constraints are embedded in a description statement.

Are we talking about the same module? I am not sure why grouping is being brought up here. There is no grouping in the module, or a refine statement.

Mike, were you referring to this description or something else?

              "Each entry contains parameters for an AMT Relay
               Address identified by the 'family' key. Under
               normal operation, these addresses SHOULD belong
               to the same address family indicated by 'family'.
               Any mismatch is an indication of abnormal
               configuration and is therefore allowed to be
               reported.

Even if not, how is this mismatch being detected in the module?

Cheers.
