18. How2Pass Router Simulation. Please read the instructions and problem statement carefully. Complete your configuration and press the Done button when finished.

    Answer :
    Troubleshooting
    In the simulation, click Host D, a dialog box will appear, select the Cisco Terminal option and press the OK button, to establish a terminal session to the router Kenan.

    Press ‹Enter› key to enter the User EXEC mode.

    Enter the privileged EXEC mode by typing enable at the Kenan> prompt and then the password how2pass at the Password: prompt. The privileged EXEC mode prompt, Kenan#, will be displayed.
    Issue the command show running-config (abbreviated as sh runn), read the output carefully to find any missing or wrong configuration. Whenever you see the prompt --More-- at the bottom of a page, you can press spacebar to see the next output page.
    Notice the running-config entries for interface serial1. It has wrong IP address and subnet mask. Notice the word shutdown below Serial1.
    To confirm this, issue show interface serial 1 command. The output confirms that the interface is shutdown.
    This simulation also supports ping, show ip protocol and show ip route commands for effective debugging.
    Do the configuration shown below and ping to a remote ip address.
    Save your configuration using copy running-config startup-config (abbreviated as copy runn start) command.
    Now press the Done button.
