The MEF Forum (MEF) has defined a rooted-multipoint Ethernet service
known as Ethernet-Tree (E-Tree).  A solution framework for supporting
this service in MPLS networks is described in RFC 7387, "A Framework                               
for Ethernet-Tree (E-Tree) Service over a Multiprotocol Label                                      
Switching (MPLS) Network".  This document discusses how those
functional requirements can be met with a solution based on RFC 7432,
"BGP MPLS Based Ethernet VPN (EVPN)", with some extensions and a
description of how such a solution can offer a more efficient
implementation of these functions than that of RFC 7796,
"Ethernet-Tree (E-Tree) Support in Virtual Private LAN Service (VPLS)".
This document makes use of the most significant bit of the Tunnel Type
field (in the P-Multicast Service Interface (PMSI) Tunnel attribute)
governed by the IANA registry created by RFC 7385; hence, it updates
RFC 7385 accordingly.

This document is a product of the BGP Enabled Services Working Group of the IETF.

This is now a Proposed Standard.
