Lab Inventory and Physical Connections

Let's take a look at R1. (Each router will be given a host name during the lab. We will use the host name as it appears on the lab diagram to refer to the different routers.) R1 is a Cisco 2500 series router with two serial ports and one Ethernet port. It is on the same segment as R2's Ethernet 0, and a TFTP server is running on the same segment (you will be using the TFTP server later in the lab). R1's Ethernet 0 and R2's Ethernet 0 are connected to a Cisco Catalyst 1900 (Cat 1900) on ports 1 and 2, respectively.

R2 is a 2514 series router. It has two serial ports and two Ethernet ports. R2's Ethernet 0 is connected to port 2 on Cat 1900, and Ethernet 1 is connected to port 3 on Cat 1900 as well. R2's Serial 0 is connected to Serial 1 on the Frame Switch router.

R3 is a Cisco 2500 series router with two serial ports and one Ethernet port. R3's Ethernet port is connected to Cat 1900 on port 4, and Serial 0 is connected to Serial 0 on the Frame Switch router. R3's Serial 1 port is connected to R5's Serial 0 port. R4 is a Cisco 2500 series router as well. It has two serial ports and one Ethernet port. R4's Ethernet port is connected to Cat 1900 on port 5. R4's Serial 0 is connected to Serial 2 on the Frame Switch router.

R5 is a Cisco 2500 series router. It has two serial ports, one Token Ring port and one ISDN BRI port. R5's Serial 0 port is connected to R3's Serial 1 port. Serial 0 on R5 is the DCE. R5's Token Ring port is connected to a standard media access unit (MAU). The BRI0 port is connected to port 2 on the Black Box ISDN simulator.

R6 is a Cisco 2500 series router. It has two serial ports, one Token Ring port and 1 ISDN BRI port. R6's Token Ring port is connected to a standard MAU. The BRI0 port is connected to port 1 on the Black Box ISDN simulator.

The terminal server is a Cisco 2511 router with 16 asynchronous ports. Each asynchronous port is connected to the console port on the back of each router in sequential order (that is, R1's console port is connected to asynchronous port 1 on the terminal server, R2's console port is connected to asynchronous port 2 on the terminal server, and so on). You will be accessing all the routers and the Catalyst 1900 switch through the terminal server. Chapter 4, "Gaining Access to the Routers and Switches," discusses the terminal server configuration.

The Frame Relay switch router is a Cisco 2523 router. It has ten serial ports, one ISDN BRI port, and one Token Ring port. The configuration of the Frame Relay switch will not be part of this lab. If you are unfamiliar with how a Frame Relay Switch operates or how to configure a Cisco router to be a Frame Relay switch, see Appendix B, "Frame Relay Switch Configuration," for more information.

NOTE

The Frame Relay switch is a very important piece of the lab. Without the Frame Switch operating correctly, you will not be able to complete the lab. We highly recommend reviewing Appendix B before continuing with the lab objectives.
