Sample MPLS configuration

Overview

The following figure shows an example of an MPLS service configuration. The actual configuration depends on the specific network requirements.

This process describes the high-level tasks that are required to configure the MPLS service example shown in the figure.

Preconfiguration
 
1 

Before you begin, verify that the following preconfigurations have been made.

  • An IGP is enabled on all participating NEs and includes the system interface in the IS-IS or OSPF area.

  • Any additional Layer 3 interfaces that you wish to use are configured.

Configuration
 
2 

Create an MPLS path.

Use the following steps:

  1. Specify 192.168.10.1 as the source network element.

  2. Specify 192.168.10.2 and 192.168.10.4 as hops.

  3. Specify interface 1/3/2 on 192.168.10.3 as the destination site. This is the final hop in the MPLS path.

3 

Create a Dynamic LSP.

Use the following steps:

  1. Specify interface 1/1/1 on 192.168.10.1 as the source IP address.

  2. Specify 192.168.10.3 as the destination IP address.

4 

Bind the Dynamic LSP created in Stage 3 to the MPLS path created Stage 2 .
