[Reference: https://www.speaknetworks.com/cisco-virl-better-gns3/, Cisco VIRL (Virtual Internet Routing Lab) is a powerful network simulation platform designed to simulate and model networks. It allows users to create and test network topologies, run simulations, and visualize network behavior in a controlled virtual environment. This tool is particularly valuable for network engineers and administrators to test configurations, troubleshoot issues, and validate network designs without the need for physical hardware., Reference: Cisco VIRL Overview, ]
