Virtual Private LAN Service (VPLS), as defined in [RFC4664], [RFC4761], and [RFC4762], is a proven and widely deployed technology. However, the existing solution has a number of limitations when it comes to redundancy, multicast optimization, and provisioning simplicity. Furthermore, new applications are driving several new requirements for other L2VPN services such as Ethernet Tree (E-Tree) and Virtual Private Wire Service (VPWS).

                   Requirements for Ethernet VPN (EVPN)


   The widespread adoption of Ethernet L2VPN services and the advent of    new applications for the technology (e.g., data center interconnect)    have culminated in a new set of requirements that are not readily    addressable by the current Virtual Private LAN Service (VPLS)    solution.  In particular, multihoming with all-active forwarding is    not supported, and there's no existing solution to leverage    Multipoint-to-Multipoint (MP2MP) Label Switched Paths (LSPs) for    optimizing the delivery of multi-destination frames.  Furthermore,    the provisioning of VPLS, even in the context of BGP-based auto-    discovery, requires network operators to specify various network    parameters on top of the access configuration.  This document    specifies the requirements for an Ethernet VPN (EVPN) solution, which    addresses the above issues.
