How to Use CCNA Network Visualizer 8.0 to Simulate Network Connections
CCNA Network Visualizer 8.0 is a software tool that allows you to create and configure virtual network devices, such as routers, switches, and hosts, and simulate their connections and interactions. It is designed to help you prepare for the Cisco Certified Network Associate (CCNA) exam, as well as to learn and practice network fundamentals.
In this article, we will show you how to use CCNA Network Visualizer 8.0 to create a simple network topology, configure basic settings on each device, and test the connectivity between them. We will also explain some of the features and benefits of this software, and how it can help you improve your network skills.
Step 1: Download and Install CCNA Network Visualizer 8.0
You can download CCNA Network Visualizer 8.0 from the official website[^1^]. The software is available as a demo version that you can use for free for 15 days, or as a full version that you can purchase for $159.00[^1^]. The software requires Internet connection for authorization, after which it can be used offline[^1^]. The software is compatible with Windows NT or later versions[^1^]. To install the software, follow the instructions on the screen.
Step 2: Create a New Project
Once you have installed and launched CCNA Network Visualizer 8.0, you will see the main window of the software. To create a new project, click on File > New Project. You will be prompted to enter a name for your project and choose a location to save it. You can also select a template for your project from the drop-down menu. A template is a predefined network topology that you can use as a starting point for your simulation. For this example, we will choose the Blank template.
Step 3: Add and Connect Devices
To add devices to your project, click on the Device menu and select the type of device you want to add. You can choose from routers, switches, hosts, hubs, bridges, repeaters, or firewalls[^1^]. For this example, we will add two routers (Router0 and Router1), two switches (Switch0 and Switch1), and four hosts (Host0, Host1, Host2, and Host3).
To connect devices to each other, click on the Connect menu and select the type of connection you want to use. You can choose from serial, Ethernet, FastEthernet, GigabitEthernet, or wireless connections[^1^]. For this example, we will use Ethernet connections. To connect two devices, click on one of their open ports and drag it to another open port of another device. A green line will indicate that the connection is successful.
Here is how our network topology looks like after adding and connecting all devices:
Step 4: Configure Devices
To configure devices on your network, double-click on any device to open its configuration window. You will see several tabs that allow you to change various settings on the device, such as IP address, subnet mask, gateway, hostname, password, interface status, routing protocol, etc[^1^]. For this example, we will configure the IP address and subnet mask of each device as follows:
Router0: IP address 192.168.1.1/24 on interface FastEthernet0/0
Router1: IP address 192.168.2.1/24 on interface FastEthernet0/0
Switch0: IP address 192.168.1.2/24 on interface VLAN1
Switch1: IP address 192.168.2.2/24 on interface VLAN1
Host0: IP address 192.168.1.10/24 on interface Ethernet0
