Setting Up the Lab
You can use any combination of routers as long as you fulfill the requirements within the topology diagram, as shown in Figure 3-1. However, it is recommended that you use the same model of routers because this makes life easier if you load configurations directly from those supplied into your own devices.

Lab Topology
This practice lab uses the topology as outlined in Figure 3-1, which you must re-create with your own equipment.
Switch Instructions
Configure VLAN assignments from the configurations supplied on the CD-ROM or from Table 3-2.

Connect your switches with RJ45 Ethernet Cross Over cables, as shown in Figure 3-2.

Frame Relay Instructions
Configure one of the routers you are going to use in the lab as a Frame Relay switch, or have a dedicated router purely for this task. This 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. Keep the encapsulation and Local Management Interface (LMI) settings to default for this exercise, but experiment with the settings outside these labs because you could be required to configure the Frame Relay switching within your actual lab.
If you are using your own equipment, keep the data circuit-terminating equipment (DCE) cables at the frame switch end for simplicity and provide a clock rate to all links from this end.
After configuration, the Frame Relay connectivity represents the logical Frame Relay network, as shown in Figure 3-3.

IP Address Instructions
In the actual CCIE lab, you find that the majority of your IP addresses are preconfigured. For this exercise you are required to configure your IP addresses as shown in Figure 3-4 or to load the initial router configurations supplied. If you are manually configuring your equipment, be sure you include the following loopback addresses:
- R1 Lo0 120.100.1.1/32
- R2 Lo0 120.100.2.1/32
- R3 Lo0 120.100.3.1/32
- R4 Lo0 120.100.4.1/32
- R5 Lo0 120.100.5.1/32
- R6 Lo0 120.100.6.1/32
- SW1 Lo0 10.1.1.1/24
- Lo1 10.1.2.1/24
- Lo2 10.1.3.1/24
- SW2 Lo0 10.2.2.1/24
- Lo1 10.2.3.1/24
- Lo2 10.2.4.1/24
- SW3 Lo0 10.33.33.1/24
- Lo1 10.33.34.1/24
- Lo2 10.33.35.1/24
- SW4 Lo0 10.44.44.1/24
- Lo1 10.44.45.1/24
- Lo2 10.44.46.1/24
