Ketan,
It would not be fair to say that these operators "wish to deploy a Traffic
Engineering solution using a subset of Segment Routing".
It would be fair to say that these operators "wish to deploy IPv6 Traffic
Engineering". Some of these operators don't care about SR. Some are actively
averse to SRv6. All they want is a Routing header.

Hi Ron,
Thanks for that clarification.
I note that you are not anymore saying "Are not interested in SR" like you had
mentioned before the WG adoption call :
https://urldefense.com/v3/__https://mailarchive.ietf.org/arch/msg/ipv6/LheyFD_uwuHp7tiG8Y1CwKngDYI/__;!!NEt6yMaO-gk!X2qW2zTZEbZRfBSE6c_KM-k7aIvZTIT9bycp3jyFJ3sTbf8MtGo4E_uGX7zYZ7lk$
So, would it be fair to say that the operator that you are referring to below,
wishes to deploy a Traffic Engineering solution using a subset of Segment
Routing (i.e. a reduced portion of Spring Architecture) that only supports
prefix and adjacency SIDs as indicated by the two "forwarding methods" that are
referred to in draft-bonica-6man-comp-rtg-hdr?
Thanks,
Ketan

Ketan,
Please consider an operator who:
- Wants a way to steer IPv6 packets through a specified path that includes many
nodes (>8)
- Does not want any of the following:
- A new VPN encapsulation technique
- A new service function chaining technique
- Network programming
- MPLS and uSID
- To encoding instructions in IPv6 addresses.
These operators want a compact routing header, nothing more.

I am looking for explanation of the "other ways" that CRH can be used (i.e.
those outside the Spring architecture). I am trying to understand from the
authors what would be the applicability of that solution, it's use-cases and
it's requirements. That is what, I believe, will help us evaluate the CRH
proposal in the context of this working call. That will help us answer these
questions like the scope of the SID, 32-bit or 16-bit or something else and
what the CRH-FIB is going to turn out like.
