Hi Ron, Some of the operators may not care about the SR name, but it is clear to me that the proposal in the CRH draft is 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". https://tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr-22#section-4 o Forward the packet to the next-hop along the least-cost path to >>> Prefix SID the next segment endpoint. o Forward the packet through a specified interface to the next >>> Adjacency SID segment endpoint. Given the use of mapping IDs and mapping FIB, the proposal is comparable more to SR-MPLS than SRv6. It is better to do a holistic analysis of any proposal such as CRH that is introducing an MPLS label like mapping construct into IPv6 architecture - doing so should be considered as a significant change to IPv6.

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.

These operators want a compact routing header, nothing more.

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.
