Router Configuration Steps in Cisco Packet Tracer 

Configuring a router in Cisco Packet Tracer involves a series of structured steps. Here, we provide an in-depth Router Configuration Steps guide to walk you through the process: 

Step 1: Access the Router 

• Launch Cisco Packet Tracer on your computer. 
• From the device palette located on the left-hand side of the interface, select and drag a router model of your choice (e.g., Cisco 2911 router) onto the workspace. 

Step 2: Establish a Console Connection 

• Click on the router device that you've placed on the workspace to select it. 
• In the physical workspace area, locate and click on the "CLI" (Command Line Interface) tab situated at the bottom of the router's interface. 
• By doing this, you'll gain access to the router's command-line interface (CLI), which is where you will perform the configuration. 

Step 3: Access Configuration Mode 

• Upon entering the CLI, you'll find yourself in the user EXEC mode, indicated by the router prompt (usually displayed as ">" or "Router>"). 
• To escalate your privileges to the privileged EXEC mode, simply type "enable" and press Enter. This will result in a change of the router prompt to "#" (e.g., "Router#"). 
• Once in the privileged EXEC mode, you can enter the global configuration mode by typing "configure terminal" or its shorthand, "conf t," and pressing Enter. 

Step 4: Configure Router Hostname 

• In the global configuration mode, set the router's hostname using the command "hostname [your_hostname]." Replace "[your_hostname]" with the desired name (e.g., "Router(config)# hostname MyRouter"). 

Step 5: Assign IP Addresses to Interfaces 

• To configure a specific interface, use the command "interface [interface_type] [interface_number]" (e.g., "interface GigabitEthernet0/0"). 
• Assign an IP address to the interface by utilizing the "ip address [IP_address] [subnet_mask]" command (e.g., "ip address 192.168.1.1 255.255.255.0"). 
• Make sure to activate the interface by typing "no shutdown." 

Step 6: Set Router Passwords 

• Enhance the security of your router by establishing passwords. Employ "enable secret [password]" to define the password for privileged EXEC mode and "enable password [password]" for user EXEC mode. 
• Configure the console line password with the "line console 0" command, followed by "password [password]." 

Step 7: Configure Routing Protocols 

• To enable routing protocols like OSPF or EIGRP, enter the corresponding protocol configuration mode (e.g., "router ospf [process_id]"). 
• Proceed to configure the router's routing settings, which include network advertisements. 

Step 8: Save Your Configuration 

• Upon completing the router configuration, it's imperative to preserve your work. This can be accomplished by executing the "write memory" or "copy running-config startup-config" command, which stores your configuration in non-volatile memory. 

Step 9: Exit Configuration Mode 

• To exit the configuration mode, enter the command "exit" or press Ctrl+Z repeatedly until you return to the privileged EXEC mode. 
• Finally, type "exit" once more to transition back to the user EXEC mode. 

Step 10: Verify and Test 

• It is vital to validate your configuration through various show commands (e.g., "show running config" or "show ip interface brief"). 
• Additionally, conduct tests within your network to ensure that it functions as expected.
