           Multi-site EVPN based VXLAN using Border Gateways
                    draft-sharma-multi-site-evpn-04

Abstract

   This document described the procedures for interconnecting two or
   more Network Virtualization Overlays (NVOs) via NVO over IP-only
   network.  The solution interconnects Ethernet VPN network by using
   NVO with Ethernet VPN (EVPN) to facilitate the interconnect in a
   scalable fashion.  The motivation is to support extension of Layer-2
   and Layer-3, Unicast and Multicast, VPNs without having to rely on
   typical Data Center Interconnect (DCI) technologies like MPLS/VPLS.
   The requirements for the interconnect are similar to the ones
   specified in RFC7209 [RFC7209] "Requirements for Ethernet VPN
   (EVPN)".  In particular, this document describes the difference of
   the Gateways (GWs) procedure and incremental functionality from
   [RFC9014] "Interconnect Solution for Ethernet VPN (EVPN) Overlay
   Networks", which this solution is interoperable with.  This document
   is OBSOLETE and replaced by [SHARMA-BESS-MULTI-SITE].

1.  Introduction

   This document described the procedures for interconnecting two or
   more Network Virtualization Overlays (NVOs) via NVO over IP-only
   network.  The solution interconnects Ethernet VPN network by using
   NVO with Ethernet VPN (EVPN) to facilitate the interconnect in a
   scalable fashion.  The motivation is to support extension of Layer-2
   and Layer-3, Unicast and Multicast, VPNs without having to rely on
   typical Data Center Interconnect (DCI) technologies like MPLS/VPLS.
   The requirements for the interconnect are similar to the ones
   specified in RFC7209 [RFC7209] "Requirements for Ethernet VPN
   (EVPN)".  In particular, this document describes the difference of
   the Gateways (GWs) procedure and incremental functionality from
   [RFC9014] "Interconnect Solution for Ethernet VPN (EVPN) Overlay
   Networks", which this solution is interoperable with.  This document
