Lab 5: Configuring a Frame Relay Switch-Part I

Lab 5: Configuring a Frame Relay Switch ”Part I

Practical Scenario

A Frame Relay switch can be of great service both in the field and in practice. A Frame Relay switch can be deployed in a lab to help model Frame Relay services that are similar to a production environment.

Lab Exercise

In this practical exercise, you configure a multipoint fully meshed Frame Relay network. This lab focuses only on the switching aspects of Frame Relay, not on the end or DTE devices.

Lab Objectives

• Configure a Cisco router to perform a Frame Relay switching function, as depicted in Figure 1-17.

  Figure 1-17. Lab 5: Physical Layout for Frame Relay Switching

  

• Configure all PVCs with ANSI LMI as the diagram depicts. The PVC mapping is as follows :

  - DLCI 112 maps to DLCI 21.

  - DLCI 113 maps to DLCI 31.

  - DLCI 32 maps to DLCI 23.

Equipment Needed

• Three Cisco routers with serial ports and one other Cisco router to perform the role of the Frame Relay switch. The Frame Relay switch must have three usable serial ports.

• A total of six serial cables, or three sets of DTE-to-DCE serial cables.

Physical Layout and Prestaging

Figure 1-17 shows the physical layout for this lab.
