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 traditional way of PW signaling, and provides fast
   protection convergence upon node or link failure.
