Example for Configuring LDP VPLS over TE (LDP)

A public network tunnel on an LDP VPLS network can be an MPLS TE tunnel.

Networking Requirements

Figure 1 Networking diagram for configuring VPLS over TE (LDP)

Interface 1, interface 2, sub-interface 1.1, and sub-interface 2.1 in this example represent GE 0/1/0, GE 0/1/8, GE 0/1/0.1, and GE 0/1/8.1, respectively.



As shown in Figure 1, CE1 and CE2 belong to the same VPLS network and access the MPLS backbone network through PE1 and PE2, respectively. OSPF is used as the IGP on the MPLS backbone network.

It is required that LDP VPLS and the dynamic signaling protocol RSVP-TE be used to establish an MPLS TE tunnel between PE1 and PE2 to transmit VPLS services.

Configuration Notes

When configuring VPLS over TE (LDP mode), note the following:

  • PEs belonging to the same VPLS network must have the same VSI ID.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on PE and P devices of the backbone network to implement interworking, and enable MPLS.

  2. Set up an MPLS TE tunnel and configure the tunnel policy. For details on how to set up an MPLS TE tunnel, see NetEngine 8000 F Configuration Guide - MPLS.

  3. Enable MPLS L2VPN on the PEs.

  4. Create VSIs on PEs, configure LDP as the signaling protocol, and bind VSIs to AC-side interfaces.

  5. Configure the VSI to use an MPLS TE tunnel.

Data Preparation

To complete the configuration, you need the following data:

  • OSPF areas enabled with TE

  • VSI name and VSI ID

  • IP addresses of peers and tunnel policy

  • Name of each interface bound to the VSI

Procedure

  1. Assign IP addresses to interfaces and configure OSPF.

    The configuration details are not provided.

  2. Configure MPLS, MPLS TE, MPLS RSVP-TE, and MPLS CSPF.

    Enable MPLS, MPLS TE, and MPLS RSVP-TE both globally and on specific interfaces on each node along the MPLS TE tunnel. Enable MPLS TE CSPF in the system view of the tunnel's ingress.

    # Configure PE1.

    [~PE1] interface Tunnel 10
[*PE1-Tunnel10] ip address unnumbered interface loopback1
[*PE1-Tunnel10] tunnel-protocol mpls te

    After completing the preceding configurations, run the display this interface command in the tunnel interface view. The command output shows that Line protocol current state is UP, indicating that an MPLS TE tunnel has been established. The following example uses the command output on PE1.

    [~PE1-Tunnel10] display this interface

    Run the display tunnel-info all command in the system view. The TE tunnel whose destination address is the MPLS LSR ID of the peer PE exists. The following example uses the command output on PE1.

    [~PE1] display tunnel-info all
Tunnel ID                     Type                Destination         Status
