  4. Network Components: A selection box at the bottom that allows you to switch between different device categories.
  5. Device Configuration: Located at the bottom right, it allows you to configure devices’ settings.

Building Your First Network Topology

Now that you’re familiar with the interface, let’s create a basic network topology.

Step 1: Adding Devices

  1. Select Devices: From the Toolbox, select a router (e.g., 1841 Router) and a switch (e.g., 2960 Switch).
  2. Drag and Drop: Drag these devices into the Workspace.

Step 2: Connecting Devices

  1. Choose Connections: Click on the “Connections” icon in the Toolbox.
  2. Select Cable Type: For this example, choose the “Automatic” connection type, which selects the appropriate cable based on the devices being connected.
  3. Connect Router to Switch: Click on the router, then on the switch to connect them.

Step 3: Adding End Devices

  1. Add PCs: From the Toolbox, select two PCs and drag them into the Workspace.
  2. Connect PCs to Switch: Use the “Automatic” connection type to connect each PC to the switch.

Step 4: Configuring IP Addresses

  1. Configure PCs:
    • Click on the first PC.
    • Go to the “Desktop” tab and select “IP Configuration”.
    • Assign an IP address (e.g., 192.168.1.2) and Subnet Mask (e.g., 255.255.255.0).
    • Repeat the process for the second PC with a different IP address (e.g., 192.168.1.3).
  2. Configure Router:
    • Click on the router.
    • Go to the “CLI” tab.
    • Enter the following commands:
      Router> enable
      Router# configure terminal
      Router(config)# interface fastethernet0/0 Router(config-if)# ip address 192.168.1.1 255.255.255.0
      Router(config-if)# no shutdown
      Router(config-if)# exit
      Router(config)# exit
      Router# write memory

Testing Your Network

With your basic network topology in place, it’s time to test the connectivity between devices.

Step 1: Ping Test

  1. Open Command Prompt: On the first PC, go to the “Desktop” tab and select “Command Prompt”.
  2. Ping Command: Type ping 192.168.1.3 to test connectivity with the second PC.

If everything is set up correctly, you should see a series of successful replies, indicating that the PCs can communicate with each other through the network.

Additional Features to Explore

Once you’re comfortable with the basics, delve into more advanced features of Cisco Packet Tracer:

  1. Network Simulation: Explore dynamic routing protocols such as OSPF, EIGRP, and BGP.
  2. IoT Simulations: Experiment with Internet of Things (IoT) devices and configurations.
  3. Multiuser Collaboration: Collaborate with peers in real-time to build complex network scenarios.
  4. Activity Wizard: Create and customize learning activities to test your networking knowledge.
