Abstract

   This document describes how EVPN can be used to support virtual
   private wire service (VPWS) in MPLS/IP networks. EVPN enables the
   following characteristics for VPWS: single-active as well as all-
   active multi-homing with flow-based load-balancing, eliminates the
   need for single-segment and multi-segment PW signaling, and provides
   fast protection using data-plane prefix independent convergence upon
   node or link failure.
