Example for Configuring Static VPWS Accessing VPLS

This section provides an example for configuring static VPWS accessing VPLS on an HVPLS network where UPEs do not support VPLS.

Networking Requirements

On the network shown in Figure 1, UPEs do not support VPLS, but CE1 and CE2 need to communicate. To meet this requirement, configure SVC VPWS on UPEs and static VPLS on SPEs.

Figure 1 Configuring static VPWS accessing VPLS

  • Interface 1, sub-interface1.1, interface 2, and sub-interface 2.1 in this example represent GE 0/1/0, GE 0/1/0.1, GE 0/1/8, and GE 0/1/8.1, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure SVC VPWS on UPEs.

  2. Configure static VPLS on SPEs.

  3. Enable MAC Withdraw for the VSI on each SPE.

Data Preparation

To complete the configuration, you need the following data:

  • VSI name and VSI ID

  • MPLS LSR IDs of UPEs and SPEs, which are used as peer IP addresses

  • Routing protocol

Procedure

  1. Configure interface IP addresses for CEs, UPEs, and SPEs in accordance with Configuration Files.
  2. Configure an IGP (OSPF in this example) on the MPLS backbone network.

    After completing the configurations, run the display mpls ldp session command on SPEs and the P. The command output shows that Status of the peer relationships between SPE1 and the P and between SPE2 and the P is Operational. Run the display mpls lsp command. The command output shows the LSP status.

    The following example uses the command output on SPE1.

    <SPE1> display mpls ldp session

  6. Verify the configuration.

    After completing the configurations, run the display mpls static-l2vc command on a UPE. The command output shows that a PW has been established and VC State is up. The following example uses the command output on UPE1.

    <UPE1> display mpls static-l2vc

    Run the display vsi name v100 verbose command on an SPE. The command output shows that the VSI named v100 is Up and the corresponding PW is also Up. The following example uses the command output on SPE1.
