Example for Configuring Interworking Between VPLS and MPLS EVPN E-LAN

If traditional VPLS is used at the aggregation layer but the core network has evolved to EVPN, interworking between VPLS and MPLS EVPN E-LAN needs to be configured.

Networking Requirements

As shown in the following figure, a VPLS network is deployed between the CSG and ASGs, and an EVPN is deployed between the RSG and ASGs. Access-side PW interfaces can be configured on ASGs to implement interworking between VPLS and MPLS EVPN E-LAN.

Figure 1 Configuring interworking between VPLS and MPLS EVPN E-LAN

Interfaces 1 through 3 in this example represent GE 0/1/1, GE 0/1/2, and GE 0/1/3, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure an IGP on each device. Because the VPLS network (between the CSG and ASGs) and EVPN (between the RSG and ASGs) reside at different layers, use different IGP processes to implement route communication.

  2. Configure basic MPLS LDP functions on the CSG, RSG, and ASGs.

  3. Configure the EVPN function on the RSG and ASGs.

  4. Configure PW connections between the CSG and ASGs.

  5. Configure BFD for PW on CSGs and ASGs.
  6. Configure an interface monitoring group on ASG1 to detect network-side interface status changes in a timely manner.

Data Preparation

To complete the configuration, you need the following data:

  • IP addresses of device interfaces

  • MPLS LSR IDs of devices

  • Names, RDs, and VPN targets of the EVPN instances created on the RSG and ASGs

Procedure

  1. Configure an IGP on each device. Because the VPLS network (between the CSG and ASGs) and EVPN (between the RSG and ASGs) reside at different layers, use different IGP processes to implement route communication.

    For configuration details, see Configuration Files in this section.

  2. Configure basic MPLS LDP functions on the CSG, RSG, and ASGs.

    For configuration details, see Configuration Files in this section.

  3. Configure the EVPN function on the RSG and ASGs.
