To simulate MikroTik networks and perform configuration testing before deploying them in a production environment, there are several software options.

Below are some of the most popular tools you can use:

1. GNS3 (Graphical Network Simulator-3)

• Description: GNS3 is an open source network simulation platform that allows you to simulate complex networks by emulating real network devices, including MikroTik routers.
• Features: It allows you to create complex network topologies, import operating system images of MikroTik routers, and simulate network traffic.
• Advantages: It is highly customizable and flexible, with a large user community and support for a wide range of devices and operating systems.

2. EVE-NG (Emulated Virtual Environment Next Generation)

• Description: EVE-NG is another network simulation platform that allows you to emulate network devices and create complex topologies.
• Features: It offers an easy-to-use web UI, support for importing images of MikroTik routers and a wide range of devices and operating systems.
• Advantages: It provides a realistic simulation experience and is suitable for network learning and testing environments.

3. VirtualBox or VMware Workstation

• Description: These are general-purpose virtualization tools that can be used to run virtual instances of operating systems, including MikroTik routers.
• Features: They allow you to create and configure virtual machines with images of MikroTik routers, connect them to each other and simulate complex networks.
• Advantages: They are easy to use and widely available, with a wide range of online resources to help with setup and use.

4. MikroTik CHR (Cloud Hosted Router)

• Description: MikroTik CHR is a virtualized version of the RouterOS operating system that can run in virtualization environments such as VirtualBox, VMware or Hyper-V.
• Features: It allows you to simulate MikroTik networks using a virtualized instance of RouterOS, providing a realistic simulation experience similar to a production environment.
• Advantages: Specifically designed by MikroTik for simulations and tests, providing high fidelity in network simulation.

These are just a few options available to simulate MikroTik networks. Each has its own characteristics, advantages and disadvantages, so it is important to evaluate your needs and preferences before choosing the right tool for your network simulations.
