Example: Configuring Frame Relay over MPLS

The script provided in this section is one way to configure Frame Relay services over MPLS. Explanation notes are provided within the script. You must change the script for your specific configuration.

The topology example shown in Figure 123 further explains the configuration script.

Note: The route interface command is used toward the end of the configuration script. You can substitute the mpls-relay command, depending on the tunneling method best for your environment.
