Not an EVPN author, but I have some a couple of comments about section

- Minor: EVPN is a separate AFI/SAFI so I would not make it a sub-section
of L2VPN, but I would rather put it at the same level. Now that the L2VPN
WG will no longer be a WG on its own, I would not classify EVPN as L2VPN
anymore. EVPN can even do L3.

- Why does EVPN inherit RFC 6074 gaps? I don’t see any gap in any of the
EVPN defined route types or procedures. I would remove that and keep the
dependency on mLDP and RFC 7117 (if any) for the PMSI tunnel attribute
that EVPN inherits. Other than that I see no gaps in EVPN.

Thank you.
