Ethernet VPN (EVPN) and Provider Backbone Bridge EVPN (PBB-EVPN)
introduce a comprehensive suite of solutions for delivering Ethernet
services over MPLS/IP networks. These solutions offer advanced
multihoming capabilities. Specifically, they support Single-Active
and All-Active redundancy modes for an Ethernet Segment (ES), which
is defined as a collection of physical links connecting a multihomed
device or network to a set of Provider Edge (PE) devices. This
document extends the concept of an ES by allowing an ES to be
associated with a set of Ethernet Virtual Circuits (EVCs), such as
VLANs, or other entities, including MPLS Label Switched Paths (LSPs)
or pseudowires (PWs). This extended concept is referred to as virtual
Ethernet Segments (vESes). This document lists the requirements and
specifies the necessary extensions to support vES in both EVPN and
PBB-EVPN.
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. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
