The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of MPLS L3VPN and EVPN.

General restrictions and guidelines

Before you configure EVPN on a device, you must perform the following tasks:

1. Set the system operating mode to VXLAN mode by using the switch-mode command in system view.

2. Save the running configuration.

3. Reboot the device.

Example: Configuring IPv4 EVPN-DCI over an MPLS L3VPN network

Network configuration

As shown in Figure 1:

· Data center 1 and data center 2 are interconnected through an MPLS L3VPN network. The two data centers can communicate with each other through the MPLS L3VPN network.

· Switch A and Switch D are distributed EVPN gateways in the data centers.

· Switch B and Switch C act as both EVPN EDs and MPLS L3VPN PEs.

Figure 1 Network diagram

Analysis

For the switches within a data center to reach each other, configure a routing protocol on the switches to advertise routes for interfaces (including the loopback interfaces). In this example, OSPF is used.

To enable communication between the data centers, you must perform the following tasks on Switch B and Switch C:

· Configure both MPLS L3VPN and EVPN.

· Configure the BGP EVPN address family and the BGP VPNv4 address family to exchange routes.

Restrictions and guidelines

As a best practice to ensure correct traffic forwarding, configure the same MAC address for all VSI interfaces on an EVPN gateway.

When you configure L3 VXLAN IDs for VSI interfaces, make sure the same route targets are configured for the VPN instances associated with these VSI interfaces.
