Lab 2-1: Router startup and Initial Configuration

Task 1: Router hardware and software inspection.

Step 1: Access the CLI of your router and enter privilege exec mode.

Step 2: Use the appropriate command to display the hardware and software properties of the router.

Fill in the table below.

Router Model
System image file
Software version

Step 3: Check the NVRAM for a startup-config file using the sh start command and the startup-configuration if one exists using the erase startup-config command.

Step 4: Issue the reload command to restart the router and observe the boot process from the console.

Task 2: Create the initial Router configuration.

Step 1: Skip the initial configuration dialog, terminate the autoinstall and enter privilege EXEC mode.

Step 2: Set the system hostname to either R1 or R2

Does the system prompt change?

Step 3: Enter the correct configuration mode to add a description to the first ethernet interface on the router (fa0/0 or gi0/0) Link to LAN Switch.

Step 4: Configure an interface IP address and mask with reflects the values shown in the Visual Topology diagram.



What is the status of the interface?

Do you think we could ping the IP address of the switch?

Take any necessary steps to enable IP connectivity between the Router and the Switch before you move on to the next step.

Step 5: Save your running-config to NVRAM

Task 3: Changing default CLI parameters.

Step 1: Change the EXEC timeout on the console port to a value of 60 minutes

Step 2: Enter the sh line con 0 command

Does this command verify the new timeout value?

Step 3: Improve the readability of the console access by synchronising unso licited messages and debug outputs with the input of the CLI.

Step 4: Use the relevant command which prevents the system from translating a mistyped command to an IP address.

Step 5: Save your running-config to NVRAM

Task 4: Neighbour discovery using CDP.

Step 1: Using the sh cdp command fill in the table below

How often are CDP advertisements being sent
How long will a CDP neighbour entry be held in the table without being refreshed
What version of CDP is currently running on your device

Step 2: Issue the sh cdp nei command and if you see any devices fill in the table below.

Device ID Local Intrfce Holdtme Capability Platform Port ID

Step 3: Execute the sh cdp nei detail command, do you see any additional information not
shown using the command in step 2.

Lab Answer Keys:

[Locker] The locker [id=4139] doesn't exist or the default lockers were deleted.
