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