Setting Up the Lab
Feel free to use any combination of routers and switches as long as you fulfill the requirements within the topology diagram, as shown in Figure 1-1. However, it is recommended to use the same model of equipment because doing so will make life easier should you load configurations directly from the supplied configurations into your own devices.

Lab Topology
This troubleshooting exercise uses the topology outlined in Figure 1-1, which you must re-create with your own equipment or by using lab equipment on the CCIE R&S 360 program.
Switch Instructions
Configure VLAN assignments from the configurations supplied or from Table 1-2.

Connect your switches together with fiber small form-factor pluggable (SFP) connectors or RJ045 Ethernet crossover cables, as shown in Figure 1-2.

Frame Relay Instructions
Configure one of the routers you are going to use in the troubleshooting lab as a Frame Relay switch, or have a dedicated router assigned solely for this task. This troubleshooting lab uses a dedicated router for the Frame Relay switch. A fully meshed environment is configured between all the Frame Relay routers. Pay attention in the lab as to which permanent virtual circuits (PVC) are actually required.
If you are using your own equipment, keep the DCE cables at the frame switch end for simplicity and provide a clock rate to all links from this end.
The Frame Relay connectivity will, after configuration, represent the logical Frame Relay network, as shown in Figure 1-3.

IP Address Instructions
For this exercise, you are required to configure your IP addresses, as shown in Figure 1-4, or load the initial router configurations supplied.
