Tarik:
Hi!
The next steps you mentioned below are:
=====
Next steps:
Addressing feedback from co-authors about gaps with the SR-Policy
architecture.
YANG DOCTOR’s review
=====
Any update on the first one? I’ll request a YANG DRs review when you
(authors) have settled.
Thanks!
Alvaro.

Hello all,
Here is a short status update on the SR Policy YANG draft since the last
IETF meeting (v07, v08).
The latest update maximizes the reuse of ietf-te-types where doing so does
not compromise SR Policy semantics, while keeping SR-specific behavior
explicit where TE reuse would otherwise blur the model.
*The main model changes currently reflected in the draft are:*
- dynamic optimization objectives now reuse the TE optimization metric
entry
- dynamic path constraints now reuse TE path metric bounds, affinities,
SRLGs, and disjointness through a path-constraints subtree
- the former SR max-sids handling is now represented through
path-metric-bounds using an SR-specific msd identity under the TE
path-metric base
- policy bandwidth keeps the SR leaf shape, but the requested and
reserved leaves now use the TE bandwidth typedef
One point that came up during review is the appearance of inherited
explicit-route-include-objects and explicit-route-exclude-objects subtrees
in the rendered YANG tree. We are not enabling those as SR Policy behavior.
They still appear because they come from the reused TE optimization
grouping, but the SR model disallows the TE route-object optimization
identities that would activate them. We have added clarification in both
the model text and the draft prose to make that explicit.
Editorially, the draft has also been updated to align the narrative with
the current model structure and naming, including the selective TE reuse
approach and the current treatment of dynamic candidate-path constraints
and objectives.
*Next steps:*
- Addressing feedback from co-authors about gaps with the SR-Policy
architecture.
- YANG DOCTOR’s review
Thank you and best regards,
Tarik

Hi Alvaro, Adrian, and WG,
We have pushed an updated revision of ietf-sr-policy-yang
https://datatracker.ietf.org/doc/html/draft-ietf-spring-sr-policy-yang-08
We have maximized the re-use of TE Grouping/definition in the SR-TE model.
We are planning to push another commit that addresses some feedbacks from
the co-authors.
Thank you and best regards,
Tarik

Hi Alvaro,
Yes, we are trying to close on long standing pending comment (re-using TE
attributes) amongst authors and have had one meeting this week already.
We plan to close this in less than two weeks time and then plan to push a
revision before the IETF cutoff date.
HTC.

Kamran:
Hi!
Just checking to see if you will push another update before I start the
Yang Dr review.
Thanks!
Alvaro.

Hi Alvaro, Adrian, and WG,
We have just pushed an updated revision for the
draft-ietf-spring-sr-policy-yang-07.txt.
This addresses some editorial comments, as well as prepares it for YANG DR
review (taking cues from your comments on srv6-yang document).
We have couple of pending items (e.g. TE attributes re-use) that are being
closed between the authors - we are working on them and trying to close in
a week time and push another update (if/as needed).
Best regards,
