Example for Configuring PBB-EVPN

This section provides an example for configuring provider backbone bridge Ethernet VPN (PBB-EVPN) to implement Layer 2 internetworking.

Networking Requirements

On the network shown in Figure 1, Site 1 and Site 2 reside on Layer 2 networks. To allow Site 1 and Site 2 to communicate over the backbone network, configure PBB-EVPN. Specifically, configure PBB-EVPN instances on provider edges (PEs) to store EVPN routes sent from customer edges (CEs) or remote provider edges (PEs) and configure a route reflector (RR) to reflect EVPN routes. To ensure high transmission efficiency, configure the All-Active redundancy mode on PE1 and PE2 to implement load balancing. To ensure service quality, configure TE tunnels and a traffic policy for PEs to use TE tunnels to transmit traffic.

Figure 1 PBB-EVPN networking

Interfaces 1 through 3 in this example represent GE 0/1/0, GE 0/1/8, and GE 0/1/16, respectively.

Precautions

When configuring PBB-EVPN, note the following:

On the same PBB-EVPN, the export VPN target list of a site shares VPN targets with the import VPN target lists of the other sites; the import VPN target list of a site shares VPN targets with the export VPN target lists of the other sites.
Using the local loopback interface address of a PE as the PBB-EVPN source address is recommended.

Configuration Roadmap

The configuration roadmap is as follows:

Configure an IGP on the backbone network to allow PEs and the RR to communicate.
Configure basic MPLS functions and MPLS LDP, and establish MPLS LSPs on the backbone network.
Configure PBB-EVPN instances and B-MAC addresses on each PE.
Configure a PBB-EVPN source address on each PE.
Bind each PE interface that connects to a CE to the I-EVPN instance on that PE.
Configure an ESI for each PE interface that connects to a CE.
Configure BGP EVPN peer relationships between PEs and the RR, and configure the PEs as RR clients.
Configure CEs and PEs to communicate.
(Optional) Configure PEs to use TE tunnels to carry traffic.

Data Preparation

To complete the configuration, you need the following data:

B-EVPN instance name (bevpn) and I-EVPN instance name (ievpn)
B-EVPN instance RDs (100:1, 200:1, and 300:1) and RTs (1:1) on PEs
ESI (0011.1001.1001.1001.1002) for the PE3 interface connecting to CE2

Procedure

Assign an IP address to each interface on the RR and PEs according to Figure 1. For configuration details, see Configuration Files in this section.

Configure an IGP on the backbone network to allow PEs and the RR to communicate. OSPF is used as the IGP in this example.

After completing the configurations, PE1, PE2, and PE3 can establish OSPF neighbor relationships with the RR. Run the display ospf peer command. The command output shows that State is Full. Run the display ip routing-table command. The command output shows that the RR and PEs have learned the routes to Loopback1 of each other.

The following example uses the command output on PE1.
