EVPN VPWS Flexible Cross-Connect Service
draft-ietf-bess-evpn-vpws-fxc-01.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.
