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is OBSOLETE and replaced by [SHARMA-BESS-MULTI-SITE].
