Hi WG,

 I agree with the modification of V-15.  And it's recommended to expedite the completion of the last call process for this standard.
 Since there is already a related 6man SRH compression draft(https://datatracker.ietf.org/doc/draft-ietf-6man-comp-rtg-hdr<https://datatracker.ietf.org/doc/draft-ietf-6man-comp-rtg-hdr/>), facing the same issue, it would be best if it could solve the upper layer checksum problem together.
 
Thanks,
Yanrong

[Moving this message up on everyone’s mailbox.]

Dear WG:

We have received no replies to this request.  If no changes are needed to §6.5 then that is ok, but if you have a different opinion please speak up.

Thanks!

Alvaro.
