Re: [bess] WG adoption and IPR poll for draft-trr-bess-bgp-srv6-args-02

I support adoption : clarifying spec and improving interop is important.

Thank you for section 4 regarding Backward Compatibility.
May be 1 comment although I didn't take time to read everything in details and I'm not familiar with EVPN.

It's not completely clear to me whether backward compatibility MAY be preserved or MUST be preserved.
Unless there is a good technical reason, my preference would be for "MUST be preserved".
e.g.
§4

OLD: Backward compatibility with implementations doing the bitwise
   logical-OR operation can be preserved by the advertisement of SIDs


NEW: Backward compatibility with implementations doing the bitwise

   logical-OR operation is preserved thanks to the advertisement of SIDs

§3.1
OLD:

it is

   REQUIRED that proper LBL, LNL, and FL values be set corresponding to

   the supported SID Structure for the End.DT2M SRv6 Service SIDs.


Given that this is already the second spec to clarify this, may be "proper [..] value" could be expanded so as to specify the precise behavior which is REQUIRED.


Probably similar comment for §3.2 ("The LBL, LNL, and FL MUST be set to appropriate values").

Thanks,
Regards,
--Bruno
