It also allows you to extend Layer 2 and Layer 3 connectivity to data center networks built with older (legacy) technologies (Spanning Tree Protocol, virtual Port Channel, Cisco FabricPath, etc.). The EVPN Multi-Site solution allows you to interconnect data center fabrics built on VXLAN EVPN technology. It assumes that the individual data center fabrics (site-internal networks) are already configured and up and running. This document focuses entirely on design, deployment, and configuration considerations for the EVPN Multi-Site architecture and the related border gateways (BGWs). The VXLAN BGP EVPN fabric can be configured either manually or using Cisco ® Data Center Network Manager (DCNM). This document assumes that the reader is familiar with the configuration of VXLAN BGP EVPN data center fabric (site-internal network). Nevertheless, this document provides best practices and recommendations for a successful deployment. VXLAN EVPN Multi-Site architecture is independent of the transport network between sites. However, the sole focus of this document is on how this extension can be achieved by using EVPN Multi-Site architecture, an integrated interconnectivity approach for VXLAN BGP EVPN fabrics.ĮVPN Multi-Site technology is based on IETF draft-sharma-multi-site-evpn. The VXLAN Border Gateway Protocol (BGP) EVPN fabric (or site) can be extended at Layer 2 and Layer 3 with various technologies. In addition to the technical details, this document presents design considerations and sample configurations to illustrate the EVPN Multi-Site approach.

This document describes how to achieve a Virtual Extensible LAN (VXLAN) Ethernet Virtual Private Network (EVPN) Multi-Site design by integrating VXLAN EVPN fabrics with EVPN Multi-Site architecture for seamless Layer 2 and Layer 3 extension.
