Hi Alvaro,

I captured the IANA registry request for E-Tree flags in the latest rev of the draft (along with other comment resolutions):

https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-etree/

This was your last AI to be completed.

Cheers,
Ali

To be clear: without the registry defined the specification is incomplete.  If possible, consider the case where someone else (not one of the authors) wants to use one of the flags, what should be the policy for them to define it?  Should it be first come first served, or would the WG prefer a Designated Expert to review the potential assignment, is it ok for an experimental draft to request assignment, or is a Standards Track document the only way?

We've probably already written more text than the actual policy definition would take... <sigh>

That is ok with me.
