Scenario A: Level 1 and Level 2 Routes
Task 1: Prepare the Network
Cable a network that is similar to the one in the topology diagram shown in Figure 8-3.
Step 1.
You can use any current router in your lab as long as it has the required interfaces shown
in the topology.

Note:
If you use 1700, 2500, or 2600 routers, the router outputs and interface descriptions will appear different.
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 interfaces on R1, R2, and R3.
Step 1.
Configure the interfaces on the R1, R2, and R3 routers with the IP addresses from Table 8-5.
