Abstract:

I find the "Conclusion" section (with the word 'justifies' replaced
with 'documents') a clearer Abstract of the document than the
current Abstract. Maybe move the Conclusion as Abstract, and move
some technical details of the current Abstract to the Introduction?
[jorge] That makes sense. I removed the conclusions section and changed the abstract to:
Ethernet Virtual Private Network (EVPN) provides a unified control-plane that solves the Network Virtualization Edge (NVE) auto-discovery, tenant MAC/IP dissemination and advanced features required by Network Virtualization Over Layer-3 (NVO3) networks. EVPN is a scalable solution for NVO3 networks and keeps the independence of the underlay IP Fabric, i.e. there is no need to enable PIM in the underlay network and maintain multicast states for tenant Broadcast Domains. This document describes the use of EVPN for NVO3 networks, discusses its applicability to basic Layer-2 and Layer-3 connectivity requirements, as well as advanced features such as MAC-mobility, MAC Protection and Loop Protection, multi-homing, Data Center Interconnect (DCI) and much more. No new EVPN procedures are introduced.

Section 1:

        TOR/Leaf switches

I had to follow the link a few sentences down to RFC 7365 to realize
TOR here does not mean Tor Onion Routing but Top of Rack switch.

RFC 7365 uses "ToR" and not "TOR" as well. So maybe expand and fix
the capitalization.
[jorge] fixed


Section 2:

The terminology is listed alphabetically, but some items are referred
in items before they are explained. It might be better to re-order
them. But perhaps not - me as a newbie in this space didn't know any,
but perhaps people familiar with terms find this sorting method easier
to use when reading the document.
[jorge] The section in version 06 is ordered alphabetically (it’s done properly this time), as discussed with John during his review.



        NVO3 tunnels or simply Overlay tunnels will be used interchangeably

Why not stick to one term for simplicity ?
[jorge] good point. I changed it to just use NVO3 tunnels all the time.
