We have few objectives of this lab which we have to do.
Verify the Default Router Configuration
Step 1: Establish a Console cable Connection to R1.
Choose a Console cable from the available connections.
Click PC-A and select RS 232.
Click R1 and select Console.
Click PC-A > Desktop tab >Terminal.
Click OK and press ENTER. You are now able to configure R1.
Step 2: Enter privileged mode and examine the current configuration.
Enter into the Router 1 Privileged mode by the following commands and them examine the current configurations of the router.
Enable the command use to Enter into the privileged EXEC mode.
Show running-config command is used to examine the current configuration of router.
Router# show running-config
Answer of the following question are as follows
What is the router’s hostname? hostname Router
How many Fast Ethernet interfaces does the Router have? 4 Fast Ethernet Interfaces.
How many Gigabit Ethernet interfaces does the Router have? 2 Gigabit Ethernet interfaces.
How many Serial interfaces does the router have? 2 Serial interfaces.
What is the range of values shown for the vty lines? Line vty 0 4.
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?
It displays this message because the configuration file was not saved to NVRAM. Currently it is only located in RAM.
Configure and Verify the Initial Router Configuration
Configure the initial settings on R1.
R1 as the hostname.
Use the following passwords:
Privileged EXEC, unencrypted: cisco
Privileged EXEC, encrypted: itsasecret
Encrypt all plain text passwords.
Message of the day text: Unauthorized access is strictly prohibited.
Verify the initial settings on R1.
Verify the initial settings by viewing the configuration for R1. What command do you use? Router# show running-config
Exit the current console session until you see the following message:
R1 con0 is now available
Press RETURN to get started.
Press ENTER; you should see the following message:
Unauthorized access is strictly prohibited.
User Access Verification
Why should every router have a message-of-the-day (MOTD) banner?
Every router should have a banner to warn unauthorized users that access is prohibited but can also be used for sending messages to network personnel/technicians (such as impending system shutdowns or who to contact for access).
If you are not prompted for a password,what console line command did you forget to configure?
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?
The enable secretpassword overrides the enable password. If both areconfigured on the Router, you must enter the enable secretpassword to enter privileged EXEC mode.
If you configure any more passwords on the router, are they display in the configuration file as plaintext or in encrypted form? Explain. The service password-encryption command encrypts all current and future passwords.
Save the Running Configuration File
Step 1: Save the configuration file to NVRAM.
You have configure the initial settings for R1. Now back up the running configuration file to NVRAM toensure 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? copy running-configstartup-config
What is the shortest, unambiguous version of this command? copy r s
Which command displays the contents of the NVRAM? show startup-configuration or showstart
Verify that all of the parameters configured are recorded. If not, analyze the output and determine whichcommands were not done or were entered incorrectly. You can also click Check Resultsin theinstruction window.
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.
Examine the contents of flash using the show flash command:
R1# show flash
How many files are currently store in flash? 3 files
Which of these files would you guess is the IOS image? file number 3
Why do you think this file is the IOS image? file number 3 contain c1900-universalk9-mz.SPA.151-4.M4.bin
Save the startup configuration
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.
Use the show flash command to verify the startup configuration file is now stored in flash.
