A new Request for Comments is now available in online RFC libraries. RFC 8317 Title: Ethernet-Tree (E-Tree) Support in Ethernet VPN (EVPN) and Provider Backbone Bridging EVPN (PBB-EVPN) Author: A. Sajassi, Ed., S. Salam, J. Drake, J. Uttaro, S. Boutros, J. Rabadan Status: Standards Track Stream: IETF Date: January 2018 Mailbox: sajassi@cisco.com, ssalam@cisco.com, jdrake@juniper.net, ju1738@att.com, sboutros@vmware.com, jorge.rabadan@nokia.com Pages: 23 Characters: 53519 Updates: RFC 7385 I-D Tag: draft-ietf-bess-evpn-etree-14.txt URL: https://www.rfc-editor.org/info/rfc8317 DOI: 10.17487/RFC8317 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. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
