Configuration Roadmap

The configuration roadmap is as follows:

Data Preparation

To complete the configuration, you need the following data:

Step 1 Configure the VLAN to which each interface belongs according to

The configuration details are not mentioned here.

Step 2 Configure an IGP.

OSPF is adopted in the example. The configuration details are not mentioned here.

After the configuration, run the display ip routing-table command on UPEs, SPEs, and PEs.

You can view that UPEs, SPEs, and PEs have learned the addresses of the loopback interfaces

from each other.

Step 3 Configure basic MPLS functions and LDP.

The configuration details are not mentioned here.

After the configuration, run the display mpls ldp session command. You can find that the

Status of the peer relationship between the UPE and the SPE or between the PE and the SPE is

Operational, which indicates that the peer relationship is established. Run the display mpls

lsp command, and you can view the setup of the LSP.

GigabitEthernet 2/0/0

GigabitEthernet 1/0/0

Complete the task of Configuring Martini VPLS between SPEs and PEs.

Establish the MPLS LDP peer relationship between UPEs and SPEs.

Create a VSI on an SPE, and specify the UPE as its PE of the lower layer.

Create a VSI on a UPE, and specify the SPE as the peer of the VSI.

Configure CE1 and CE2 to access UPE, and configure CE3 to access PE.

Names and IDs of VSIs

MPLS LSR IDs (as IP addresses of peers) of UPE, SPE, and PE

Routing protocol UPE, SPE, and PE

Do not add the AC-side port and PW-side port of a PE to the same VLAN; otherwise, a loop may occur.
