            Interconnect Solution for EVPN Overlay networks
                  draft-ietf-bess-dci-evpn-overlay-05

Abstract

   This document describes how Network Virtualization Overlays (NVO) can
   be connected to a Wide Area Network (WAN) in order to extend the
   layer-2 connectivity required for some tenants. The solution analyzes
   the interaction between NVO networks running EVPN and other L2VPN
   technologies used in the WAN, such as VPLS/PBB-VPLS or EVPN/PBB-EVPN,
   and proposes a solution for the interworking between both.
