Example for Configuring Hard-Pipe Static PWs of a VPLS

This section provides an example for configuring hard-pipe static PWs of a VPLS to carry leased line services.

Networking Requirements

IP hard pipe for a VPLS is a pipe technology that establishes a static PW over a static bidirectional co-routed LSP to simulate an SDH leased line.

In an IP hard pipe scenario, the hard pipe function needs to be configured for PWs on the public network side. On the network shown in Figure 1, an LDP VPLS connection is configured between PE1 and PE2. VSIs must be created on PEs with specified VC labels.

Figure 1 Hard-pipe static PW networking

  • Interfaces 1 and 2 in this example represent GE 0/1/0 and GE 0/1/8, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Enable an IGP on the backbone network for devices to communicate with each other.

  2. Enable MPLS and MPLS L2VPN.

  3. Configure an LDP VPLS connection between PEs and specify VC labels

  4. Configure IP hard pipe bandwidth reservation on main interfaces.

Data Preparation

To complete the configuration, you need the inner labels and outer labels of the static L2VC connection.

The outer label of PE1 is the same as the inner label of PE2; whereas the inner label of PE1 is the same as the outer label of PE2.

Procedure

  1. Assign IP addresses to interfaces on the CEs, PEs, and P as shown in Figure 1.
  2. Configure an IGP (OSPF in this example) on the MPLS backbone network.
  3. Configure basic MPLS functions on the MPLS backbone network.

  9. Bind a VSI to an interface.

    # Configure PE1.

    [~PE1] interface gigabitethernet 0/1/0

  10. Verify the configuration.

    1. Check VPLS connection information.

      Run the display vsi command on each PE to check the hard pipe-based LDP VPLS connection information. The command output shows hard-pipe static PW information of the VPLS. The following example uses the command output on PE1.

      [~PE1] display vsi name vsi1 verbose
