Task 1: Prepare the Network

Cable a network that is similar to the one in the topology diagram of Figure 9-8.

Step 1.

You can use any current router in your lab as long as it has the required interfaces shown
in the topology.

Clear any existing configurations on the routers. Step 2.

Task 2: Perform Basic Router Configurations
Perform basic configuration of the R1, R2, and R3 routers according to the following guidelines:

Configure the router host name.

■

Disable Domain Name System (DNS) lookup.

■

Configure an EXEC mode password.

■

Configure a message-of-the-day banner.

■

Configure a password for console connections.

■

Configure a password for VTY connections.

■

Task 3: Configure and Activate Serial and Ethernet
Addresses

Configure the interfaces on the R1, R2, and R3 routers. Step 1.

Configure the interfaces with the IP addresses from Table 9-4.

Verify IP addressing and interfaces.

Step 2.

Use the show ip interface brief command to verify that the IP addressing is correct and
that the interfaces are active.

When you have finished, be sure to save the running configuration to the NVRAM of the
router.
