15-CCNA 200-301 (Router Basic Configuration) By Eng-Walid Saad Eldin | Arabic

Introduction

This tutorial provides a comprehensive guide to basic router configuration, specifically tailored for the CCNA 200-301 exam. Understanding how to configure routers is essential for network professionals, as it forms the backbone of networking concepts. This guide will take you through the essential steps to set up a router effectively.

Step 1: Connect to the Router

• Use a console cable to connect your computer to the router's console port.
• Open a terminal emulator software (like PuTTY or Tera Term) on your computer.
• Set the connection parameters:
  • Baud rate: 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow control: None
• Click "Open" to establish the connection.

Step 2: Enter Privileged EXEC Mode

• Once connected, press Enter to access the router's command line interface (CLI).
• Type enable and press Enter to enter Privileged EXEC mode.
• If prompted, enter the enable password.

Step 3: Enter Global Configuration Mode

• From Privileged EXEC mode, type configure terminal or conf t and press Enter.
• You’ll see the prompt change to indicate you are in Global Configuration mode.

Step 4: Configure Hostname

• Set a unique hostname for the router using the command:

  hostname YourRouterName
  

• Replace YourRouterName with a name of your choice.

Step 5: Set Up Passwords

• Configure a console password:

  line con 0
  password YourPassword
  login
  

• Set an enable password:

  enable secret YourEnablePassword
  

• Replace YourPassword and YourEnablePassword with your own secure passwords.

Step 6: Configure Interfaces

• Identify the interface to configure (e.g., FastEthernet 0/0).
• Enter the interface configuration mode:

  interface FastEthernet0/0
  

• Assign an IP address and subnet mask:

  ip address 192.168.1.1 255.255.255.0
  

• Activate the interface:

  no shutdown
  

• Exit back to Global Configuration mode with exit.

Step 7: Set Up Routing (Optional)

• Configure a static route if necessary:

  ip route 0.0.0.0 0.0.0.0 <NextHopIPAddress>
  

• Replace <NextHopIPAddress> with the next hop router's IP address.

Step 8: Save Configuration

• To ensure all your configurations are retained after a reboot, save your work:

  write memory
  

• Alternatively, use:

  copy running-config startup-config
  

Conclusion

You have successfully configured a basic router setup. Key steps included connecting to the router, entering necessary modes, configuring passwords, setting IP addresses on interfaces, and saving your configuration.

For further learning, you may explore more advanced topics such as dynamic routing protocols, Access Control Lists (ACLs), and VLAN configurations. These skills will be invaluable for your CCNA journey and professional networking tasks.
