Hi,

I have the following comments/suggestions/questions:

Idnits reported:

  -- The draft header indicates that this document updates RFC8365, but the
     abstract doesn't seem to mention this, which it should.
[Jorge] good point. Added.


Would this update 7432 as well?
[Jorge] since 7432bis obsoletes 7432 and refers to this document, it is probably ok not to say it updates 7432… but I don’t have a strong opinion. It may depend on how fast 7432bis progresses as well?


  == Outdated reference: A later version (-06) exists of
     draft-ietf-bess-evpn-geneve-05

I normally don't reference a specific revision of a document, unless the revision number matters. If you remove the revision in the reference, you'll not need to worry about updating it again.
[Jorge] sure, done.


Given that this is ahead of rfc7432bis, the "EVPN ESI Multihoming Attributes" registry creation for the 1-octet Flags field in the ESI Label Extended Community should be moved to this draft.
[Jorge] As long as this document it is really ahead of 7432bis, sure. We added it to the IANA section, and we can always remove it if 7432bis goes out before this one.


"MPLS-based IP Tunnel" does not seem to be accurate to me. It should be "IP-based MPLS Tunnel". Related to that, the three tunnel types can be renamed to:

- IP-based MPLS Tunnel
- (SR-)MPLS Tunnel
- IP Tunnel

I don't think we need "group" in terms like "group MPLS-based IP" - it can simply be "IP-based MPLS".
[Jorge] ok, changed


There a few references like the following:

   [RFC9012] BGP Encapsulation extended community

I believe the reference should be put after the relevant text:

   BGP Encapsulation extended community [RFC9012]
[Jorge] ok, fixed.



Thanks.
Jeffrey
