Before You Start

Before You Start

Before configuring Ethernet virtual private network (EVPN), familiarize yourself with the usage scenario, complete the pre-configuration tasks, and obtain the required data. This can help you complete the configuration task quickly and accurately.

Usage Scenario

Functioning as the control plane of Virtual Extensible LAN (VXLAN), EVPN allows EVPN routes to be exchanged so that VXLAN tunnel endpoints (VTEPs) can be automatically discovered and host information can be mutually advertised.

This section describes the EVPN networking configuration. As shown in Figure 6-5, the hosts need to communicate with the Layer 3 network between sites. EVPN can be configured to meet this requirement.

Pre-configuration Tasks

Before configuring EVPN functions, complete the following tasks:

  • Configure an IGP on the PEs and Ps of a backbone network to ensure IP connectivity.

  • Configure IP addresses for the interfaces that connect CEs to PEs.

Data Preparation

To configure EVPN functions, you need the following data.

No.

Data

1

VPN instance data, including:
  • VPN instance name
  • RD and EVPN-VPN target of the VPN instance IPv4 address family

2

IP addresses of interfaces that connect PEs to CEs

3

IP addresses of interfaces that connect CEs to PEs

4

AS numbers of PEs, and interfaces and IP addresses used by PEs to establish Border Gateway Protocol (BGP) peer relationships

5

Type of the routing protocol running between PEs and CEs, such as static route, RIP, OSPF, IS-IS, or BGP
