Document: draft-ietf-lisp-gpe-06
Reviewer: Stewart Bryant
Review Date: 2018-08-24
IETF LC End Date: 2018-09-06
IESG Telechat date: Not scheduled for a telechat

Summary:

This is a well written draft, and I assume that everyone in the WG is happy
that the reduction in size of the Nonce/Map-Version field will not be a problem
in operational networks.

However, I do have a question of why this is being published now on the
Standards Track with a normative reference to draft-ietf-lisp-6834bis.
draft-ietf-lisp-6834bis is only a few weeks old. It will take its time to get
through the IETF process and of course technically may change. If 
draft-ietf-lisp-gpe is approved by the IESG  it will simply sit on the RFC
Editor's queue until draft-ietf-lisp-6834bis gets through the system, and even
then if there is a change to draft-ietf-lisp-6834bis, then draft-ietf-lisp-gpe
may need to be pulled all the way back to the WG depending on the nature of the
change.

Maybe the plan is that ietf-lisp-rfc6830bis will only take a short while to
finish because I see that other bis drafts will also stall on it. If not I
would have thought that a better approach would be to make this experimental
and point to RFC6834. Then, when RFC6834bis is published to make this draft a
PS pointing to it.

Whatever the conclusion this matter will need to be clearly written up in the
Shepherd's report.

Major issues: No technical issues, but see summary.

Minor issues: None

Nits/editorial comments: None
