How to simulate network projects using GNS3?

In the process of certification practice for Juniper, Cisco and other vendor applications, network architecture and simulation and for learning purposes, GNS3 is broadly applicable. To begin GNS3 operation and establish a simple network simulation, we propose a thorough operating procedure of GNS3 in a gradual manner:

Step 1: Download GNS3

1. Download GNS3: According to your operating system like Linux, macOS or windows, download the advanced version of GNS3 by approaching the GNS3 website. Among all-in-one versions or autonomous editions, select the best one for your system. For more complicated simulation, it incorporates GNS3 VM.
2. Install GNS3: Execute the installer and pursue the interactive directions. Verify the compatible virtualization environment like VirtualBox, VMware Workstation or VMware Player, whether it is installed in your computer, if you are planning to deploy a GNS3 VM.

Step 2: Configure GNS3

1. Launch GNS3: Open GNS3 platform. The Setup Wizard directs you through the original configuration, while you initially execute the application. If you are selected to deploy it, it incorporates the installation of GNS3.
2. Add Appliances: The appliances are network devices such as firewalls, routers and switches are involved in GNS3. Import manual configuring device applications or appliance templates to insert appliances. From the GNS3 marketplace or trader, you have to acquire legal and proper software images such as QEMU, IOS, IOU and IOSv.

Step 3: Develop a New Project

1. Start a New Project: To begin an original project, click ‘File’ >’ New Blank Project’ > present your project name and select a location to save it. The network topologies and configurations are stored in the GNS3 project.
2. Develop your Network: By means of dragging and dropping devices upon the workspace, make use of the left-side toolbar. To synthesize with real networks, you could include switches, PCs (VPCS), routers and even cloud mechanisms.

Step 4: Connect the Devices

1. Draw Connections: In order to see its ports, intersect the device. To develop a link, click and drag from one device’s port to another. For the connection process, GMS3 often deploys the suitable cable type.
2. Configure Devices: To open the console window, you must double-click on a device. As you perform real hardware, you could configure the device by deploying CLI commands. You have a necessity to load OS and conduct preliminary installation procedures for devices which execute IOS or other operating systems.

Step 5: Begin the Simulation

1. Power on Devices: Start the simulation process by right clicking on a device and choose ‘Start’ to power it on. Click the ‘Start/Resume all devices’ button in the toolbar to begin all devices in the topology.
2. Access the Console: For opening the console window, where you can enter commands to configure and manage the device, you should double-click on it once the device is begun.

Step 6: Test and Analyze the Network

1. Basic Configuration: As needed for your network design, allocate IP addresses and configure routing protocols on your device.
2. Testing Connectivity: To verify connections and ensure the network, whether it performs as expected, implement commands such as traceroute and ping from the device consoles.
3. Use Capture Feature: Among devices, GNS3 enables you to capture and evaluate packets on the links. To utilize these characteristics with Wireshark for intensive traffic analysis, right-click on a link and choose ‘Start Capture’.

Step 7: Save and Export the Project

• Save Your Work: Keep in mind that, to save your project GNS3 accesses others to load and view your network topology and configurations as well as it can be transferred and exported.
