Configuring EVC VPLS Accessing L3VPN

Configuring EVC VPLS Accessing L3VPN

This section describes how to create a VBDIF interface to implement EVC VPLS accessing L3VPN.

Usage Scenario

EVC interfaces are Layer 2 interfaces that do not support IP addresses. If EVC L2VPN accessing L3VPN is required, you must create a BD-based interface, or VBDIF interface. A VBDIF interface is a Layer 3 interface that supports IP address configuration. The VBDIF interface allows communication with the L3VPN.

As shown in Figure 10-7, on the access network, the CSG provides a BD for user site access and connects to the ASG over a VPLS PW; on the bearer network, the ASG uses the VBDIF interface to terminate the VPLS PW and establishes an L3VPN with the RSG.

Figure 10-7 EVC VPLS accessing L3VPN

Pre-configuration tasks

Before configuring EVC VPLS accessing L3VPN, complete the following task:

Procedure

  1. Configure EVC VPLS on the CSG and ASG. For configuration details, see Configuring EVC VPLS.
  2. Create VPN instances on the ASG and RSG and establish an MP-IBGP peer relationship. For configuration details, see Configuring Basic BGP/MPLS IP VPN.
  3. Create a VBDIF interface on the ASG and bind the VBDIF interface to the L3VPN.
    1. Run system-view

      The system view is displayed.

    2. Run interface vbdif bd-id

      A VBDIF interface is created, and the VBDIF interface view is displayed.

      The VBDIF interface number must be the ID of a BD that has been created.

    3. Run ip binding vpn-instance vpn-instance-name

      A VPN instance is bound to the VBDIF interface.

    4. Run ip address ip-address { mask | mask-length } [ sub ]

      An IP address is assigned to the VBDIF interface.

  4. Run commit

    The configuration is committed.
