Document: draft-lin-idr-sr-policy-headend-behavior-03
Purpose: Extension to distribute SR policies carrying headend behavior
Overview: This draft has 3 problems that need to be addressed prior to an adoption call.
The IDR chairs welcome a presentation on the draft at the 5/20/2024 interim
1st Problem: Please update this document to refer to current drafts
1. draft-ietf-idr-segment-routing-te-policy – has been replaced by the following two drafts:
draft-ietf-idr-sr-policy-safi, and
draft-ietf-idr-bgp-sr-segtypes-ext,
Since this draft refers to mechanisms and security considerations in draft-ietf-idr-segment-routing-te-policy, please verify that the references are still valid.
1. draft-jiang-idr-ts-flowspec-srv6-policy – has been replaced by draft-ietf-idr-ts-flowspec-srv6-policy
2. draft-filsfils-spring-srv6-neg-pgm-insertion – has expired.
Please review the changes in these drafts to make sure your text still applies.
2nd Problem: Are these L2 Headend Behavior features approved by Spring WG?
It is not clear whether the extension in draft-filsfils-spring-srv6-neg-pgm is being adopted by the Spring WG.
3rd Problem: Section 3 of this draft suggests that [draft-ietf-idr-bgp-ls-sr-policy] will be extended to include headend behavior.
Prior to IDR adoption, it would be useful to provide details on:
1. Why the BGP-LS mechanism need to be augmented to include headend behaviors.
2. What BGP Update packets or procedures need to be updated to carry the headend behaviors.
Next steps: The authors should:
1. Update their draft to address problem 1.
2. Ask the Spring WG whether L2 headend behaviors described in draft-filsfils-spring-srv6-neg-pgm has ben approved by IDR.
3. Provide additional details on what BGP-LS mechanisms or TLVs need to be updated to handle the headend behaviors.
The IDR chairs welcome a presentation of the updated draft at the 5/20/2024 interim.
Cheerily, Susan Hares
