         Usage and applicability of BGP MPLS based Ethernet VPN
                     draft-ietf-bess-evpn-usage-09

Abstract

   This document discusses the usage and applicability of BGP MPLS based
   Ethernet VPN (EVPN) in a simple and fairly common deployment
   scenario. The different EVPN procedures are explained on the example
   scenario, analyzing the benefits and trade-offs of each option. This
   document is intended to provide a simplified guide for the deployment
   of EVPN networks.
