Part 1: Verify the Default Router

Part 2: Configure and Verify the
Initial Router Configuration
Part 3: Save the Running
Configuration File
Background
In this activity, you will perform basic router
configurations. You will secure access to the CLI and console port using
encrypted and plain text passwords. You will also configure messages for users logging
into the router. These banners also warn unauthorized users that access is
prohibited. Finally, you will verify and save your running configuration.
Part 1: Verify the Default Router Configuration
Step 1:
Establish a console connection to
R1.
a.
Choose a Console cable from the available connections.
b.
Click PCA and select RS 232.
c.
Click R1 and select Console.
d.
Click PCA > Desktop tab >
Terminal.
e.
Click OK and press ENTER. You are
now able to configure R1.
Step 2:
Enter privileged mode and
examine the current configuration.
You can access all the router commands
from privileged EXEC mode. However, because many of the privileged commands
configure operating parameters, privileged access should be password-protected
to prevent unauthorized use.
a.
Enter privileged EXEC mode by
entering the enable command.
Router> enable
Router#
Notice that the prompt changed in the
configuration to reflect privileged EXEC mode.
b.
Enter the show running-config command:
Router# show
running-config
c.
Answer the following questions:
What is the router’s
hostname? ______________
How many Fast
Ethernet interfaces does the Router have? _______
How many
Gigabit Ethernet interfaces does the Router have? _______
How many
Serial interfaces does the router have? _______
What is the
range of values shown for the vty lines? ______________
d.
Display the current contents of
NVRAM.
Router# show
startup-config
startup-config is not present
Why does the router respond
with the startup-config is not present message?
____________________________________________________________________________________
____________________________________________________________________________________
Part 2: Configure and Verify the Initial Router Configuration
To configure parameters on a router, you
may be required to move between various configuration modes. Notice how the
prompt changes as you navigate through the router.
Step 1:
Configure the initial settings
on R1.
Note: If you have difficulty remembering the commands, refer to the
content for this topic. The commands are the same as you configured on a
switch.
a.
R1 as the hostname.
b.
Use the following passwords:
1)
Console: letmein
2)
Privileged EXEC, unencrypted: cisco
3)
Privileged EXEC, encrypted: itsasecret
c.
Encrypt all plain text
passwords.
d.
Message of the day text: Unauthorized
access is strictly prohibited.
Step 2:
Verify the initial settings on
R1.
a.
Verify the initial settings by
viewing the configuration for R1. What command do you use?
____________________________________________________________________________________
b.
Exit the current console
session until you see the following message:
R1 con0 is now available
Press RETURN to get started.
c.
Press ENTER; you should see the following message:
Unauthorized access is strictly prohibited.
User Access Verification
Password:
Why should every router have a
message-of-the-day (MOTD) banner?
____________________________________________________________________________________
____________________________________________________________________________________
____________________________________________________________________________________
If you are
not prompted for a password, what console line command did you forget to configure?
____________________________________________________________________________________
d.
Enter the passwords necessary
to return to privileged EXEC mode.
Why would the enable secret password allow access to the privileged EXEC mode and
the enable password no longer be valid?
____________________________________________________________________________________
____________________________________________________________________________________
If you configure any more passwords on
the router, are they displayed in the configuration file as plain text or in
encrypted form? Explain.
____________________________________________________________________________________
Part 3: Save the Running Configuration File
Step 1:
Save the configuration file to
NVRAM.
a.
You have configured the initial
settings for R1. Now back up the
running configuration file to NVRAM to ensure that the changes made are not
lost if the system is rebooted or loses power.
What command did you enter to save the
configuration to NVRAM?
____________________________________________________________________________________
What is the
shortest, unambiguous version of this command? __________________________________
Which command displays the contents of
the NVRAM?
____________________________________________________________________________________
b.
Verify that all of the
parameters configured are recorded. If not, analyze the output and determine
which commands were not done or were entered incorrectly. You can also click Check Results in the instruction window.
Step 2:
Optional bonus: Save the startup
configuration file to flash.
Although you will be learning more about
managing the flash storage in a router in later chapters, you may be interested
to know now that —, as an added backup procedure —, you can save your startup
configuration file to flash. By default, the router still loads the startup
configuration from NVRAM, but if NVRAM becomes corrupt, you can restore the
startup configuration by copying it over from flash.
Complete the following steps to save the
startup configuration to flash.
a.
Examine the contents of flash
using the show flash
command:
R1# show
flash
How many
files are currently stored in flash? _______
Which of
these files would you guess is the IOS image? ____________________________________________________________________________________
Why do you think this file is the IOS
image?
____________________________________________________________________________________
b.
Save the startup configuration
file to flash using the following commands:
R1# copy
startup-config flash
Destination filename [startup-config]
The router prompts to store the file in
flash using the name in brackets. If the answer is yes, then press ENTER; if not, type an appropriate name
and press ENTER.
c.
Use the show flash command to verify the startup configuration file is now
stored in flash.
