Hi WG,

I would like to express my support for the adoption of all three documents.


I believe these drafts address a practical operational gap in SRv6 Policy 
deployment by providing explicit administrative controls over segment list 
installation. The hierarchical dependency between the drafts is clear and 
logical.





Questions for Spring WG:


1) Do these drafts correct implement 
[draft-ietf-spring-srv6-policy-sid-list-opt] concepts?>---YES


   


2) Do you see any problem with the adoption of any of these three drafts:---NO





 


Question for IDR:


1) Are there any problems in the technology descriptions?---NO


2) Does the status and setting of this flag work?---YES     Are the “delays” 
inherent in BGP distribution a concern?---NO


3) Does this draft help operators deploy SRv6?---YES


 





Question for Spring and IDR:


1)  Does this draft open any error issues?


         ---I have no further technical issues to raise at this point.




















Best regards, 


Shengnan

1) draft-lin-idr-sr-policy-admin-flags, 2) 
draft-liu-idr-sr-segment-list-optimize, 3) 
draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt (6/22/2026 to 
7/14/2026


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 endpoint39s 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 route39s 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
