Introduction

This document provides examples for configuring EVPN-DCI over an MPLS L3VPN network.

General restrictions and guidelines

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

1.     Set the system operating mode to standard mode by using the system-working-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.

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

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

Figure 1 Network diagram

 

Analysis

For the routers within a data center to reach each other, configure a routing protocol on the routers 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 Router B and Router C:

·     Configure both MPLS L3VPN and EVPN.

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

Software versions used

This configuration example was created and verified on Release 3606.

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.
