Alvaro and all,
Regarding the proposal for using a dedicated Ethertype for SRv6:
Please note that RFC explicitly “introduces two data-plane instantiations of SR: SR over MPLS (SR-MPLS) and SR over IPv6 (SRv6)” and defines SRv6 as the instantiation of SR on the IPv6 data plane.

From my POV using a dedicated Ethertype for SRv6 would directly contradict these definitions.

My 2c,
Sasha

Subject: [EXTERNAL] [spring] Separating Threads (draft-ietf-spring-srv6-srh-compression)

Dear WG:

While the chairs strongly appreciate the engagement in the discussions
around the SRv6 compression draft, several topics have gotten tangled,
and the subject lines do not help track the conversation. Following
this note will be two messages intended to serve as an anchor for
separate aspects of the discussion related to this document.  If we
get the descriptions wrong, please correct us.  If there are other
concerns (quite likely, given the engagement), please start separate
threads.

One discussion aspect has been whether SRv6 should have a distinct
Ethertype. The intarea WG has discussed an existing proposal [1]. To
avoid fragmentation, please move the discussion on this topic to the
intarea mailing list. Copying spring and 6man is appropriate. We note
that various descriptions on email have been unclear as to what is
required of whom ([1] has a specific proposal). Please be clear about
what is proposed/requested.

Thanks!

Alvaro
