Example for Configuring Static VPLS

This section provides an example for configuring static VPLS.

Networking Requirements

On the network shown in Figure 1, VPLS is enabled on PE1 and PE2. CE1 connects to PE1, CE2 connects to PE2, and CE1 and CE2 reside on the same VPLS network. If PE1 and PE2 are unable to support large numbers of LDP sessions or you want to manually manage and allocate VC labels, configure a static VPLS PW for CE1 and CE2 to communicate.

Figure 1 Networking diagram for configuring static VPLS

Interface 1, sub-interface 1.1, 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 0/1/81, respectively.

Configuration Notes

When configuring static VPLS, note the following:

PEs belonging to the same L2VPN must have the same VSI ID.

Configuration Roadmap

The configuration roadmap is as follows:

Configure a routing protocol on the backbone network to implement interworking.
Establish tunnels between PEs for transmitting service data.
Enable MPLS L2VPN on the PEs.
Create a VSI on each PE, configure static VPLS, and bind the VSI to the AC interface.

Data Preparation

To complete the configuration, you need the following data:

VSI names and IDs
IP addresses and a tunnel policy used for setting up a peer relationship
Names of interfaces bound to the VSI

Procedure

Assign an IP address to each interface on the PEs and P according to Figure 1, and configure an IGP. In this example, OSPF is used as the IGP protocol.
When configuring OSPF, advertise the 32-bit loopback interface addresses (LSR IDs) of PE1, P, and PE2.

For configuration details, see Configuration Files in this section.

After the configurations are completed, run the display ip routing-table command on PE1, P, and PE2. The command output shows the routes that the devices have learned from each other.
Configure basic MPLS functions and LDP.
For configuration details, see Configuration Files in this section.

After completing the configuration, run the display mpls ldp session command on PE1, P, and PE2. The peer relationships have been set up between PE1 and P, and between P and PE2. The status of the peer relationship is Operational. Run the display mpls lsp command to view information about MPLS LSP establishment.

Enable MPLS L2VPN on each PE.

Verify the configuration.

After completing the configuration, run the display vsi name a2 verbose command on PE1. You can see that the VSI named a2 has set up a PW to PE2 and the VSI status is up.
