Topology Diagram Background / Preparation In this activity, you will use the Cisco IOS CLI to apply an initial configuration to a router, including host name, passwords, a message-of-the-day (MOTD) banner, and other basic settings. Note: Some of the steps are not graded by Packet Tracer. Step 1: Configure the router host name. a. On Customer PC, use the terminal emulation software to connect to the console of the customer Cisco 1841 ISR. Set the host name on the router to CustomerRouter by using these commands.

Router> enable Router# configure terminal Router(config)# hostname CustomerRouter Step 2: Configure the privileged mode and secret passwords. a. In global configuration mode, set the password to cisco. CustomerRouter(config)# enable password cisco Set an encrypted privileged password to cisco123 using the secret command. CustomerRouter(config)# enable secret cisco Step 3: Configure the console password. a. In global configuration mode, switch to line configuration mode to specify the console line. CustomerRouter(config)# line console 0 Set the password to cisco123 , require that the password be entered at login, and then exit line configuration mode. CustomerRouter(config-line)# password cisco123 CustomerRouter(config- line)# login CustomerRouter(config- line)# exit CustomerRouter(config)#

Test the banner and passwords. Log out of the router by typing the exit command twice. The banner displays before the prompt for a password. Enter the password to log back into the router. You may have noticed that when you enter a command incorrectly at the user or privileged EXEC prompt, the router pauses while trying to locate an IP address for the mistyped word you entered. For example, this output shows what happens when the enable command is mistyped. CustomerRouter> emable Translating "emable"...domain server (255.255.255.255) To prevent this from happening, use the following command to stop all DNS lookups from the router CLI. CustomerRouter(config)# no ip domain-lookup Save the running configuration to the startup configuration. CustomerRouter(config)# end CustomerRouter# copy run start Step 6: Verify the configuration. a. Log out of your terminal session with the Cisco 1841 customer router. b. Log in to the Cisco 1841 Customer Router. Enter the console password when prompted. c. Navigate to privileged EXEC mode. Enter the privileged EXEC password when prompted. d. Click the Check Results button at the bottom of this instruction window to check your work. Conclusion: Thus, we have successfully learned basic configuration of router.
