   The Metro Ethernet 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 RFC7387 ("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 RFC7432, BGP MPLS Based Ethernet VPN (EVPN), with
   some extensions and how such a solution can offer a more efficient
   implementation of these functions than that of RFC7796, E-Tree
   Support in Virtual Private LAN Service (VPLS). This document makes
   use of the most significant bit of the "Tunnel Type" field (in PMSI
   Tunnel Attribute) governed by the IANA registry created by RFC7385,
   and hence updates RFC7385 accordingly.
