Re: Adoption: draft-li-idr-bgp-ls-sr-policy-path-segment-03.txt and draft-li-sr-policy-path-segment-01.txt [9/17 to 10/1/2019]

Support as a co-author. Path Segment is very useful in SR-MPLS and SRv6 passive PM, Bidirectional Path correlation, etc.
BGP SR Policy is a major mechanism to install SR policy, so I think it is correct to use BGP SR policy to assign path segment since this is part of SR policy.
The reasons to BGP-LS are similar.


1)      Should this SR Policy technology be included in BGP for SR-MPLS
Yes


2)      Is this technology a good way to implement the required

Features in BGP?

Yes



3)      Is this technology ready for adoption?

Yes, the text of  current version is mature and ready for adoption.

Also, we were required to update the IANA part for helping implementation in the previous revision.



4)      Do you have any concerns about adopting this technology?
Yes, we will update the draft to support multiple bidirectional path in ECMP by copying weight TLV to SR Bidir path sub-TLV in the near future.

Many thanks,
Cheng

Subject: [Idr] Adoption: draft-li-idr-bgp-ls-sr-policy-path-segment-03.txt and draft-li-sr-policy-path-segment-01.txt [9/17 to 10/1/2019]

This begins a 2 week WG Adoption call two related drafts [9/17 to 10/1/2019]

*         draft-li-bgp-ls-sr-policy-path-segment-03.txt and

*         draft-li-idr-sr-policy-path-segment-01.txt.

You can access these two drafts at the following location:

https://datatracker.ietf.org/doc/draft-li-idr-bgp-ls-sr-policy-path-segment/

https://datatracker.ietf.org/doc/draft-li-idr-sr-policy-path-segment/

The authors have pointed out that the adoption of this
draft since the following  SR-MPLS Path Segment draft has been adopted:

https://tools.ietf.org/html/draft-ietf-spring-mpls-path-segment-00

Please consider the following questions in your responses?


1)      Should this SR Policy technology be included in BGP for SR-MPLS



Spring has adopted the draft, but IDR can provide feedback

to spring about putting this technology in BGP.


2)      Is this technology a good way to implement the required

Features in BGP?



3)      Is this technology ready for adoption?



4)      Do you have any concerns about adopting this technology?



Cheers, Susan Hares
