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.

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.

R1 10.1.1.1/24

R2 10.1.1.2/24

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

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

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

Task 1: Router hardware and software inspection.

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

R#sh ver

Fill in the table below.

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

R#sh start

R#erase startup-config

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

R#reload

confirm

Task 2: Create the initial Router configuration.

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

Router>enable

Router#

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

Router#conf t

Router(config)#host R1

or

Router(config)#host R2

Does the system prompt change?

YES

R1(config)#

or

R2(config)#

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.

R(config)#int fa0/0

or

R(config)#int gi0/0

R(config-if)description Link to LAN Switch

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

R1 10.1.1.1/24
R2 10.1.1.2/24
R1 only.....
R1#conf t
R1(config)#int fa0/0 or R1(config)#int gi0/0
R1(config-if)#ip address 10.1.1.1 255.255.255.0
R2 only.....
R2#conf t
R2(config)#int fa0/0 or R2(config)#int gi0/0
R2(config-if)#ip address 10.1.1.2 255.255.255.0

What is the status of the interface?

administrative down

Use one of the following commands to determine the status.

R#sh ip int brief

or

R#sh int fa0/0

or

R#sh int gi0/0

The majority of Layer 3 interfaces are shut down by default, whereas layer 2 switch ports are enabled by default.

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

NO

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

R(config-if)#no shut

Step 5: Save your running-config to NVRAM

R#copy run start

Task 3: Changing default CLI parameters.

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

R#conf t
R(config)#line con 0
R(config-line)# (you are now in the console line configuration mode)
R(config-line)#exec-timeout 60

Step 2: Enter the sh line con 0 command

Does this command verify the new timeout value?

Yes idle exec 01:00:00

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

R(config-line)#logging synchronous

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

R(config)#no ip domain-lookup

Step 5: Save your running-config to NVRAM

R#copy run start

Task 4: Neighbour discovery using CDP.

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

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

The detail option can be used to display layer 3 information such as an IP address.
