Setting up a Cisco Router

This section discusses the setup for the Cisco routers in the Internet Lab. The Cisco

routers in the lab should run IOS 11.2 or a later version. Each router must have 2

Ethernet interfaces (10 Mbps or 100 Mbps) and one synchronous serial interface.

There are numerous Cisco routers that are suitable for the Internet lab: Cisco 2514, Cisco

2611 with a serial WAN interface card, or Cisco 36xx, Cisco 7xxxx with suitable interface

cards.

Label the routers as Router1, Router2, Router3, and Router4. You may also want to label

the interfaces.

Step 1: Starting a router

A router is started by turning on the power switch. The operating system (IOS) boots from

NVRAM or flash memory. If the router has a slotted chassis, then the interface cards must

be installed in the slots of the router. Insert an Ethernet interface card in slot 0 and a

synchronous serial interface in slot 1.

Step 2: Establishing a serial connection

Connect the console port of the router via a serial cable to the serial port of a PC or a

dumb terminal. The console port of recent Cisco routers have a RJ-45 connector with

rollover cabling.

If you are connecting to the console port from the serial console of a PC, you need a DB-9

to RJ-45 adaptor. Older PCs routers have a DB-25 connector at the console port, and

require different adapters.

Step 3: Accessing the router using Kermit

If you are working on a Linux PC, create a kermit session to establish a command

interface to the router. Instructions can be found in Part 2 of Lab 3. Start kermit by typing.

Here is the sequence of commands:

PC1% kermit

[/root]C-kermit>

[/root]C-kermit> set line /dev/ttyS0 (or /dev/ttyS1)

[/root]C-kermit> set carrier-watch off

[/root]C-kermit> connect
