Dear members of the WG and authors of the draft,

I am writing this email asking you to clarify what's the suggested behavior
when PMSI Tunnel Type is set to "Ingress Replication" (type 6) as
draft-ietf-bess-evpn-overlay-10 only suggests what to do with multicast
tunnel trees.

I think the originating PE should conform with RFC6514 and RFC7432 (from
which you've taken inspiration) and always (RFC2119 MUST) attach PMSI
Tunnel attribute with the Tunnel Type set to Ingress Replication and Tunnel
Identifier set to a routable address of the PE itself (more specifically NVE's
IP address).

Is that correct?
In that case i suggest to add the following line at the end of Section 9.
"""
For Ingress Replication the PE should follow what's stated in RFC6514
Section 5 .
"""
URL to RFC6514 section 5: https://tools.ietf.org/html/rfc6514#section-5

Thank you

Regards
