Hi 6man WG,

I do not support the adoption.

For CRH based solution, the VPN context is encoded in a Destination Option
header located after the CRH. At the egress PE, the packet arrives with both
CRH and Destination Option headers. The egress PE will need to process TLVs
in DOH, which is not hardware efficient. The same applies to Ingress PE that
need to encapsulate topological instructions in CRH and service instructions
in DOH.

I think there is no need for defining a new data-plane (CRH) apparently more
complicated.

I hope the WG could consider this point in the adoption call.

Thanks
Yisong

主题: Adoption Call for "The IPv6 Compact Routing Header (CRH)"

This message starts a two-week 6MAN call on adopting:

 Title:          The IPv6 Compact Routing Header (CRH)
 Authors:        R. Bonica, Y. Kamite, T. Niwa, A. Alston, L. Jalil
 File Name:      draft-bonica-6man-comp-rtg-hdr-21
 Document date:  2020-05-14

 https://tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr

as a working group item. Substantive comments regarding adopting this
document should be directed to the mailing list.  Editorial suggestions can
be sent to the authors.

Please note that this is an adoption call, it is not a w.g. last call for
advancement, adoption means that it will become a w.g. draft.  As the
working group document, the w.g. will decide how the document should change
going forward.

This adoption call will end on 29 May 2020.

The chairs note there has been a lot of discussions on the list about this
draft.   After discussing with our area directors, we think it is
appropriate to start a working group adoption call.  The authors have been
active in resolving issues raised on the list.

Could those who are willing to work on this document, either as
contributors, authors or reviewers please notify the list.   That gives us
an indication of the energy level in the working group
to work on this.

Regards,
Bob and Ole
