Example for Configuring EVPN VPWS over MPLS (Dual-Homing Active-Active)

This section provides an example for configuring EVPN VPWS services on a dual-homing active-active network.

Networking Requirements

On the network shown in Figure 1, PE1, PE2, the RR, and PE3 belong to the same AS. They need to communicate with each other using OSPF, and MPLS tunnels need to be deployed to carry EVPN VPWS services.

Figure 1 Configuring EVPN VPWS over MPLS

Interfaces 1 through 3 in this example represent GE0/1/0, GE0/1/8, and GE0/1/16, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP on the backbone network to allow PEs and the RR to communicate.

  2. Configure basic MPLS functions and enable MPLS LDP to establish LDP LSPs on the backbone network.

  3. Configure EVPN VPWS and EVPL instances on each PE and bind the EVPL instance to an access-side sub-interface.

  4. Establish BGP EVPN peer relationships between PEs and the RR. On the RR, configure the PEs as RR clients.

  5. Configure FRR on PEs.

Data Preparation

To complete the configuration, you need the following data:

  • EVPN instance name: evrf1

  • EVPN instance RDs: 100:1, 100:2, and 100:3; RTs: 1:1

Procedure

  1. Configure interface addresses on the RR and PEs according to Figure 1. For configuration details, see Configuration Files in this section.
  2. Configure an IGP on the backbone network to allow PEs and the RR to communicate. OSPF is used as the IGP in this example.
