Packet Tracer - Configure Initial Router Settings What is the router’s hostname? Router How many Fast Ethernet interfaces does the Router have? 4 How many Gigabit Ethernet interfaces does the Router have? 2 How many Serial interfaces does the router have? 2 What is the range of values shown for the vty lines? 4 d.
Display the current contents of NVRAM.
Rout er # show startup-config st ar t up- conf i g i s not pr esent Why does the router respond with the st ar t up- conf i g i s not pr esent message? the router was not configured in before
Part 2: Configu re and Verify the Initial Router Confi gur ation 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:
Config ure the init ial settin gs 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: Unaut hor i zed access i s str i ct l y pr ohi bi t ed .
Step 2: a.
Verify the init ial settin gs on R1.
Verify the initial settings by viewing the configuration for R1. What command do you use? show run
b.
Exit the current console session until you see the following message:
R1 con0 i s now avai l abl e Pr ess RETURN t o get st ar t ed. c.
Press ENTER; you should see the following message:
Unaut hor i zed access i s st r i ct l y pr ohi bi t ed. User Access Ver i f i cat i on Pass wor d:
Packet Tracer - Configure Initial Router Settings Why should every router have a message-of-the-day (MOTD) banner? to prevent and warn anyone who could login and misuse the router, and imply to them that they could be prosecuted if they login without authorization
If you are not prompted for a password, what console line command did you forget to configure? line console 0 + login 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? the enable secret overwrites the enable password + adds the encryption.
If you configure any more passwords on the router, are they displayed in the configuration file as plain text or in encrypted form? Explain. no they will be encrypted since we used the service password-encryption
Part 3: Save the Running Configu ration File Step 1: a.
Save the conf igur ation file to NVRAM.
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? copy run start What is the shortest, unambiguous version of this command? copy run start Which command displays the contents of the NVRAM? show run
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:
Packet Tracer - Configure Initial Router Settings b.
Save the startup configuration file to flash using the following commands:
R1# copy startup-config flash Dest i nat i on f i l ename [ st ar t up- conf i g] The router prompts to store the file in flash using the name in b rackets. 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.
