Dear Susan Hares,
I am a co-author on draft-liu-idr-sr-segment-list-optimize-06.txt, and I don't know of any undisclosed IPR on that draft.

Greetings:
This is an adoption 3 week WG adoption call sent to IDR and Spring for the following 3 drafts:
1. draft-lin-idr-sr-policy-admin-flag-05.txt –
2. draft-liu-idr-sr-segment-list-optimize-06.txt
3. draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt
Both WGs must agree that these drafts are useful and appropriate.
The authors of these three drafts should respond to this email with an IPR Statement specifying the following:
1) draft you are a co-author on,
2) Whether you know of any IPR on that draft.
Background for the WG and Spring.
[I-D. draft-ietf-spring-srv6-policy-sid- list-opt] specifies procedures to indicate whether the endpoint's node SID needs to be included or excluded when installing the SRv6 Policy.
1) draft-lin-idr-sr-policy-admin-flags specifies as Segment List Administrative Flags as segment list SubTLV. Flags include:
S- admin shutdown, B- backup ineligible, I-Ignore service route's Prefix SID, D- drop upon invalid (section 8.2, RFC9256), and E – eligible.
2) draft-liu-idr-sr-segment-list-optimize = adds a flag of flag INF-Flag to Segment list administrative flags specified by draft-lin-idr-sr-policy-admin-flags. The value (1) for INF-Flags indicates endpoint node SID is included in installing SID list(s) of the Candidate Path (CP) when set.
3) draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt - send INF-Flag in BGP-LS
Why 3 drafts in 1 call?
As you can see from the description, if draft-lin-idr-sr-policy-admin-flags is not adopted – then the other two drafts cannot be adopted.
Similarly, if draft-liu-idr-sr-segment-list-optimized is not adopted, then draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution cannot be adopted.
Questions for Spring WG:
1) Do these drafts correct implement [draft-ietf-spring-srv6-policy-sid-list-opt] concepts?>
2) Do you see any problem with the adoption of any of these three drafts:
(draft-lin-idr-sr-policy-admin-flag-05.txt, draft-liu-idr-sr-segment-list-optimize-06.txt, draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt)
Question for IDR:
1) Are there any problems in the technology descriptions?
2) Does the status and setting of this flag work? Are the “delays” inherent in BGP distribution a concern?
3) Does this draft help operators deploy SRv6?
Question for Spring and IDR:
1) Does this draft open any error issues?
Please include in your comments – Support or No support for adoption.
Cheerily, Susan Hares
