Introduction

This tutorial will guide you through the process of configuring IP addresses on a Cisco router, as demonstrated in Jeremy's IT Lab's CCNA Day 8 Lab. This practical exercise is crucial for anyone preparing for the CCNA 200-301 exam, providing hands-on experience with network configuration.

Step 1: Access the Router

  • Connect to the Cisco router using a console cable and terminal emulator software (e.g., PuTTY).
  • Ensure that your terminal settings are correctly configured (usually 9600 baud rate, 8 data bits, no parity, 1 stop bit).

Step 2: Enter Privileged EXEC Mode

  • Once connected, enter privileged EXEC mode by typing the following command:
    enable
    
  • You may need to enter a password if prompted.

Step 3: Enter Global Configuration Mode

  • Enter global configuration mode where you can make changes to the router's configuration:
    configure terminal
    

Step 4: Configure Interface IP Address

  • Identify the interface you want to configure (e.g., GigabitEthernet0/0).
  • Enter the interface configuration mode:
    interface GigabitEthernet0/0
    
  • Assign the IP address and subnet mask:
    ip address [IP_ADDRESS] [SUBNET_MASK]
    
    • Replace [IP_ADDRESS] and [SUBNET_MASK] with the desired values (e.g., 192.168.1.1 255.255.255.0).

Step 5: Activate the Interface

  • Enable the interface to make it operational:
    no shutdown
    

Step 6: Verify the Configuration

  • Exit back to privileged EXEC mode:
    exit
    
  • Use the following command to verify that the interface is configured correctly:
    show ip interface brief
    
  • Check that the interface status is "up" and the IP address is correctly assigned.

Step 7: Save the Configuration

  • To ensure that your configuration persists after a reboot, save the changes:
    write memory
    
    or
    copy running-config startup-config
    

Conclusion

You have successfully configured an IP address on a Cisco router. Remember to verify your configuration and save it to prevent loss of changes. For further practice, consider setting up additional interfaces or experimenting with different IP address schemes. This hands-on experience is invaluable for mastering the CCNA material.
