Hi Linda, Thanks for your review and support! Please find the reply to your questions inline with [Shunwan]. Best Regards, Shunwan From: Idr [mailto:idr-bounces@ietf.org] On Behalf Of Linda Dunbar Sent: Wednesday, August 31, 2022 12:56 AM To: idr@ietf.org; Susan Hares <shares@ndzh.com> Subject: Re: [Idr] draft-jiang-idr-ts-flowspec-srv6-policy-07.txt - (8/17/2022 to 8/31/2022 I have read the draft and support the WG Adoption. Question: Will you add an example showing the Flowspec filter rules for directing a flow to an SRv6 Policy? [Shunwan] Do you want an examples similar to that on page 5 of draft-dmc-idr-flowspec-tn-aware-mobility-02 ? If yes, we will provide an example later. Will you consider the encoding style of https://datatracker.ietf.org/doc/draft-dmc-idr-flowspec-tn-aware-mobility/ to direct a flow to an SRv6 policy? [Shunwan] What we understand is that you're referring to the style of Section 5 of draft-dmc-idr-flowspec-tn-aware-mobility-02. Is it right£¿ If yes, our answer is no. Basic idea of draft-jiang-idr-ts-flowspec-srv6-policy-07 is: Flowspec NLRI + Redirect IP Action + Policy Color + PrefixSID (Optional); Using Nexthop from Redirect IP Action and Policy Color to associate with the SRv6 Policy (C, N). This solution reuses various existing protocol components and does not require new protocol extensions. In addition, this solution is the same as the SR Policy framework in which service routes use (C, N) to associate with SR Policy. NITS: ¡¤ Abstract section: ¡°aslo¡± -> ¡°also¡± ¡¤ ¡°information¡± -> ¡°information¡± ¡¤ Page 3: ¡°The color is a 32-bit numerical value that associates the SRv6 Policy¡± -> ¡°The color is a 32-bit numerical value that associates with the SRv6 Policy¡± [Shunwan] Ack, will update them in next revision. Thank you again for your careful review!
