Hi Susan and WG,

I support this adoption. It is a good solution using flowspec to steer packets into an SRv6 policy. 

  

Best Regards,

Liyan

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 – redirect original flow


C = 1 – 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
