Configuring the CCC VLL

Configuring the CCC VLL

The CCC VLL does not require signaling negotiation or exchange of control packets; therefore, it consumes few resources and is easy to configure. However, it requires manual configuration and makes network maintenance and expansion difficult. This mode applies to small-scale MPLS networks with simple topologies.

Pre-configuration Tasks

  • Enabling basic MPLS capabilities on the PE and P devices of the MPLS backbone network before configuring a local CCC connection


  • Configure a local CCC connection.

    To create a local CCC connection, you only need to configure the inbound and outbound interfaces of the CCC connection on the PE device. Perform the following operations on the PE device:

    1. Run system-view

      The system view is displayed.

    2. Run mpls l2vpn

      MPLS L2VPN is enabled and the MPLS L2VPN view is displayed.

      Enable MPLS L2VPN on the PE device before you configure a VLL.

    3. Run quit

      Return to the system view.

    4. Run ccc ccc-connection-name interface interface-type1 interface-number1 [ raw | tagged ] out-interface interface-type2 interface-number2 [ raw | tagged ]

      A local CCC connection is created.

      The local CCC connection is bidirectional; therefore, only one connection is required.

Verifying the Configuration

After you complete configuring the CCC VLL, run the following commands to check information about the CCC connection and interfaces used by the connection.

  • Run the display vll ccc [ ccc-name | type local ] command to check information about a CCC connection.
  • Run the display l2vpn ccc-interface vc-type ccc [ down | up ] command to check information about interfaces used by the CCC connection.
