Abstract:
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 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 a
description of how such a solution can offer a more efficient
implementation of these functions than that of RFC7796, "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 RFC7385; hence, it updates
RFC7385 accordingly. This document obsoletes RFC8317.
