Yes, network simulations can be developed with MikroTik using GNS3 (Graphical Network Simulator-3). GNS3 is a versatile and powerful network simulation tool that allows you to design and configure complex virtual networks.

It can emulate, configure, test, and troubleshoot real and virtual networks, allowing networking professionals and students to experiment with network configurations without the need for physical hardware.

To simulate MikroTik networks in GNS3, you can use MikroTik's RouterOS in the form of CHR (Cloud Hosted Router) images.

The CHR is a version of RouterOS designed to run as a virtual machine, making it ideal for simulation and testing scenarios in GNS3. Here's a basic guide to get you started:

Get the CHR Image from MikroTik

First, download the latest version of MikroTik CHR image from its official website. This image is specifically designed to work in virtual environments.

Import CHR Image to GNS3

After installing GNS3, you can import the CHR image to GNS3 by creating a new virtual machine template. GNS3 supports integration with a variety of VM emulators, such as VMware Workstation, VMware Player, VirtualBox, and QEMU, the latter being commonly used with CHR images.

Configure the Network

Once the CHR image is imported and configured in GNS3, you can begin designing your network. This includes configuring routers, switches, and other interconnected virtual networks according to your simulation needs.

Simulate and Test

With everything configured, you can simulate different network scenarios, configure RouterOS features, test scripts, and practice with various MikroTik RouterOS functionalities in a controlled and secure environment.

Using GNS3 to simulate MikroTik networks is a great way to learn more about MikroTik capabilities and configurations without the risk of impacting a production network. It is especially useful for students, IT professionals looking to improve their skills, and for planning and testing new network configurations before implementing them in the real environment.
