Hi Sue and WG,


I support the adoption of this draft.



1£© I agree.  I think the introduction of action bit C can be more flexible to meet the needs of different scenarios.

2£© I agree.

3£© It is very helpful for the deployment of SRv6 network.

As a vendor, our device has implemented the traffic steering mechanism using BGP Flowspec with SRv6 Policy, and also successfully  participated in the series of joint interoperability tests.



Best regards,

Yuanxiang

This begins a 2 week WG adoption call for draft-jiang-idr-ts-flowspec-srv6-policy-07.txt
https://datatracker.ietf.org/doc/draft-jiang-idr-ts-flowspec-srv6-policy/

During your discussion of this draft, please consider:

1) Do you agree with extending 8955 and 8956 to carry the
action bit [C] found for IPv4 and IPv6 found
draft-ietf-idr-flowspec-redirect-ip-02.txt

Figure 1 : Local Administrator

0                   1
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|          Reserved           |C|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

C = 0 ¨C redirect original flow
C = 1 ¨C redirect copy of original flow

This bit augments the Redirect to IP action in RFC8955
And RFC8956.

2) Do you agree with this document use of this feature
in addition to  draft-ietf-idr-flowspec-path-redirect
https://datatracker.ietf.org/doc/draft-ietf-idr-flowspec-path-redirect/

See the following thread for a discussion of this in March:
 https://mailarchive.ietf.org/arch/msg/idr/HENTMEoiMJGmcMuVz7LTYclCSdw/

3) Will this work help deployment of SRv6 networks?

We¡¯ll discuss this draft at the IDR interim on 8/29/2022.

Cheerily, Susan Hares
