Hi Zhenqiang, 

thank you for your reply!

For point 3 and 4, I think addi= ng more descriptions might make it clearer.

Thank you!

Hello Sandy,

Thank you very much for your comments and questions. Sorry for the= late response.

1. Will add in next version.
2. As defined in RFC9256, = the headend of a SR policy is specified as an IPv4 or IPv6 addre= ss.
3. No, not always. It depends on the application scen= ario. When the last SID of a SR policy path is not USD flavored, a srv6 sid action is needed.
4. Yes, you = can. draft-ietf= -idr-flowspec-srv6 defines match rules for BGP Flowspec, and this doc defi= nes actions for BGP Flowspec. So, they can work together. The message matc= hing the rules defined in  draft-ietf-idr-flowspec-srv6 will be redirected to the SR= policy defined in this doc. A new segment list will be encapsulated in th= e new outer header.

Subject: [Idr] Re= : Request for comments on draft-li-idr-flowspec-sr-policy

Hi Zhenqiang, 

After reading this draft, I have = some questions and comments: 

1. In section 2.1, it would be better to add a reference to = the color extended community in RFC9256 in the description of policy color= ;

2. Under what circu= mstances is it necessary to use the redirection to SRv6 policy when the en= dpoint is IPv4?

3= . When the sr-policy in section 2.1 and the srv6 sid in section 2.2 are us= ed together, is it necessary to always use the SRv6 SID as the last segmen= t?

4. Can this dr= aft be used with the match operation defined in draft-ietf-idr-flowspec-sr= v6? If so, what is the operation on the message when the match condition i= s matched? If the original message has a segment list, should the original= segment list be removed and a new segment list be used?

Thank you for your consideration= !

Best regards,

Sandy

Hello all,
A new draft, https://da= tatracker.ietf.org/doc/draft-li-idr-flowspec-sr-policy/, was submitted in March, which difines two new standard actions for the BGP Flowspec = version 2 protocol: Redirect to SR Policy Action and SRv6 SID= Action. The former allows traffic to be directed to a designated SR P= olicy, while the latter enables the encapsulation of an additional SRv6= SID as needed during redirection.

Comments are appre= ciated!

Thanks and Regards,
