               EVPN VPWS Flexible Cross-Connect Service 
                  draft-ietf-bess-evpn-vpws-fxc-00.txt

Abstract

   This document describes a new EVPN VPWS service type specifically for
   multiplexing multiple attachment circuits across different Ethernet
   Segments and physical interfaces into a single EVPN VPWS service
   tunnel and still providing Single-Active and All-Active multi-homing.
   This new service is referred to as flexible cross-connect service. It
   also describes the rational for this new service type as well as a
   solution to deliver such service.
