Re: [Idr] draft-jiang-idr-ts-flowspec-srv6-policy-07.txt - (8/17/2022 to 8/31/2022

[Linda Dunbar <[e-mail]>]

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?
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?



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"

Inserted below are the Answers to the questions of the WG adoption:

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/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-jiang-idr-ts-flowspec-srv6-policy%2F&data=05%7C01%7Clinda.dunbar%40futurewei.com%7Ce1ba2985b66548c9682008da8a872957%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637974610403821442%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=fUXe%2F5uPNSvV9SwqBpEzJMVqiQPjR2gwdzgjqZwJ%2BeI%3D&reserved=0>

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 - redirect original flow
C = 1 - redirect copy of original flow

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

[Linda] Yes.


2) Do you agree with this document use of this feature
in addition to  draft-ietf-idr-flowspec-path-redirect
