[spring] Re: [Internet][BGP-LS] WG Adoption call - draft-ietf-idr-bgp-ls-sr-policy-admin-flags-00.txt [7/20 to 8/10]

["wisdomtan(谭智)" <[e-mail]>]

Hi WG,

Support the adoption of this draft.






1) Does draft-lin-bgp-ls-sr-policy-admin-flags – provide the correct flags to be queried by BGP-LS?

Are there some missing?  Is this a good start?  Are there technical flaws

Yes.

2) After asking question 1, consider does it still make sense to merge draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00 and draft-lin-bgp-ls-sr-policy-admin-flags-03.txt. 

    Yes.

3) Is there any drafts in the same area that should be considered?

   No.

I missed a step in the calls in the combination of calls below.&nbsp; I did not specifically call for an adoption of draft-lin-bgp-ls-sr-policy-admin-flags-03.txt in the call for 3 drafts attached below prior to combining it with draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt.  
 
&nbsp;
 
This starts a WG adoption call for draft-lin-bgp-ls-sr-policy-admin-flags-03.txt.&nbsp; The authors should reply to this message  with an IPR statement. 
 
&nbsp;
 
The WG should consider: 
 
1) Does draft-lin-bgp-ls-sr-policy-admin-flags – provide the correct flags to be queried by BGP-LS? 
 
&nbsp;&nbsp;&nbsp; Are there some missing?&nbsp; Is this a good start? &nbsp;Are there technical flaws

2) After asking question 1, consider does it still make sense to merge draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00 and draft-lin-bgp-ls-sr-policy-admin-flags-03.txt.

PS – thank you to the IDR chair team and especially Jie Dong our secretary for catching my error.

Hi Sue,
 
&nbsp;
 
We have merged draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt into draft-lin-bgp-ls-sr-policy-admin-flags-03 and  renamed it as: draft-ietf-idr-bgp-ls-sr-policy-admin-flags-00.txt.
 

 Currently, the focus is on merging and making some descriptive modifications, with no technical changes.
 
 Please help review if there are any issues. 
 
&nbsp;
 
If everything looks good, we will submit after July 18.
 
&nbsp;
 
&nbsp;
 
Thanks,
 
Changwang

Hi Sue,
 
&nbsp;
 1.&nbsp; The attachment is the merged document of draft-lin-idr-sr-policy-admin-flags-05 and draft-liu-idr-sr-segmentlist-optimize-06.txt.


 Since individuals cannot submit documents at the moment, could you please check if it is convenient to help submit and upload the merged document: draft-ietf-idr-sr-policy-admin-flags-00.

 
 &nbsp;
 2.&nbsp; draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt should merge the text with draft-lin-bgp-ls-sr-policy-admin-flags-03. This is currently being revised and will  be sent to you for review tomorrow.

 
 &nbsp;
 
Thank you.
 
&nbsp;
 
&nbsp;
 
Thanks,
 
Changwang

The IDR chairs have determined that there is consensus to adopt these three 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 
 
&nbsp;
 
The authors of draft-lin-idr-sr-policy-admin-flags-05 and draft-liu-idr-sr-segmentlist-optimize-06.txt should merge their two documents. &nbsp;The final  document should be submitted as:&nbsp; draft-ietf-idr-sr-policy-admin-flags-00.  
 
&nbsp;
 
draft-ali-idr-bgp-ls-sr-policy-sl-opt-distribution-00.txt should merge the text with &nbsp;draft-lin-bgp-ls-sr-policy-admin-flags-03. The authors should  send the text to me ([e-mail] ) for review.&nbsp; The final draft will be submitted as draft-ietf-idr-bgp-ls-sr-policy-admin-flags. 
 
&nbsp;
 
Thank you, 
 
Sue Hares

&nbsp;
 
Greetings: 
 
&nbsp;
 
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 
 
&nbsp;
 
Both WGs must agree that these drafts are useful and appropriate. 
 
&nbsp;
 
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. 
 
&nbsp;
 
Background for the WG and Spring. 
 
&nbsp;
 
&nbsp;[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 &nbsp;Policy.
 
&nbsp;
 
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  = &nbsp;adds a flag of flag INF-Flag to Segment list administrative flags specified by draft-lin-idr-sr-policy-admin-flags. &nbsp;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  - &nbsp;send INF-Flag in BGP-LS 
 
&nbsp;
 
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. 
 
&nbsp;
 
Questions for Spring WG: 
 
1) Do these drafts correct implement [draft-ietf-spring-srv6-policy-sid-list-opt] concepts?&gt; 
 
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) 
 
&nbsp;
 
Question for IDR:
 
1) Are there any problems in the technology descriptions? 
 
2) Does the status and setting of this flag work? &nbsp;Are the “delays” inherent in BGP distribution a concern? 
 
3) Does this draft help operators deploy SRv6? 
 
&nbsp;
 
Question for Spring and IDR: 
 
1) &nbsp;Does this draft open any error issues? 
 
&nbsp;
 
Please include in your comments – Support or No support for adoption. 
 
&nbsp;
 
Cheerily, Susan Hares
