Example for Configuring Dual-Homing Single-Active EVPN VPWS over MPLS (Active/Standby Status Determined by the DF Election Result)

This section provides an example for configuring dual-homing PEs to determine the active/standby status of PEs based on the DF election result in a scenario where a CE is dual-homed to PEs and accesses an EVPN VPWS over MPLS network in single-active mode.

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. CE1 is dual-homed to PE1 and PE2 in single-active mode. PE1 and PE2 are configured to determine the active/standby status based on the DF election result. To improve reliability, associate CFM with the EVPN DF election function and configure local-remote FRR.

Figure 1 Dual-homing single-active EVPN VPWS over MPLS networking

Interfaces 1 through 3 in this example represent GigabitEthernet0/1/0, GigabitEthernet0/1/8, and GigabitEthernet0/1/16, 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. Configure an ESI and the dual-homing single-active mode; configure the PEs to determine their active/standby status based on the DF election result.

  5. Configure local-remote FRR.

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

  7. Configure CEs to access PEs through physical interfaces.

  8. Associate CFM with the EVPN DF election function.

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 an IGP in this example.
