Border Provisioning Use Case in VXLAN BGP EVPN Fabrics - Multi-Site
This section explains how to connect two Virtual eXtensible Local Area Network (VXLAN) Border Gateway Protocol (BGP) Ethernet VPN (EVPN) fabrics through DCNM using the EVPN Multi-Site feature. The EVPN Multi-Site configurations are applied on the Border Gateways (BGWs) of the two fabrics. Also, you can connect two member fabrics of a Multi-Site Domain (MSD).
Introduced in DCNM 11.0(1) release, MSD is a multifabric container that is created to manage multiple member fabrics. It is a single point of control for definition of overlay networks and VRFs that are shared across member fabrics. See Multi-Site Domain for VXLAN BGP EVPN Fabrics section in the Control chapter for more information on MSD.
For a detailed explanation on the EVPN Multi-Site feature, see the VXLAN BGP EVPN Multi-Site Design and Deployment document.
Configuration methods - You can create underlay and overlay Inter-Fabric Connections (IFCs) between member fabrics through auto-configuration and through the DCNM GUI.
vPC configuration is supported for BGWs with the role Border Gateway from Cisco DCNM Release 11.1(1).
Supported destination devices - You can connect a VXLAN fabric to Cisco Nexus and non-Nexus devices. A connected non-Cisco device can also be represented in the topology.
