As is customary, I have done my AD review of draft-ietf-sfc-nsh-18.  First, I would like to thank the editors, Carlos, Uri, and Paul, as well as the many contributors for their work on this document.  It has improved substantially.

I do have a few minor comments from my review.  They are below.  I will proceed to ask for an IETF Last Call now and schedule this draft for Aug 31; for that telechat date, I will require a very active shepherd as well as editors.

Please do SUBMIT the latest editor's version of this draft ASAP.  Version numbers are cheap and it is much better for reviewers to see the latest version. This must be the process going forward to avoid the same points being brought up multiple times.

Sounds good.

1) As Acee already noted, receivers of unassigned flags MUST ignore the value.  There are a couple places to fix this.

Agreed. Done.

2) Given the consensus in NVO3 and that VXLAN-GPE will be progressed as an informational document described an alternative that was not selected for standardization, I would prefer a different example in Sec 6.1 Table 1.

This is just an example, non normative, non-binging, and list VXLAN-GPE along with GRE and Ethernet. What would you prefer the document uses?

3) In Sec 7.1, there is a sentence "In some cases they may terminate, and be able to inspect encrypted traffic."  Unless there is a strong technical need to point this out, I would pick a different example.  There is a great deal of current controversy and discussion happening in TLS currently - and this is likely to trigger that discussion unnecessarily.

Ack. Gone.

4) I am happy to see that IEEE (https://regauth.standards.ieee.org/standards-ra-web/pub/view.html#registries) is now showing the EtherType 0x894F as referring to this draft.  Thanks!

Anytime :-)

Thanks!

Carlos.

Regards,
Alia
