Hands-On Network Simulation with Cisco Modeling Labs (CML2)

Setting up physical lab hardware is expensive, space-consuming, and difficult to manage. Cisco Modeling Labs (CML2) provides a powerful, virtualized alternative to design, test, and troubleshoot network topologies on your own computer. This text-based course guides you through the foundational concepts of network simulation using CML2. You will transition from understanding basic virtualization concepts to building, configuring, and automating multi-node networks using industry-standard virtual images. What you'll learn: - Understand the core architecture, system requirements, and licensing of Cisco Modeling Labs - Create and configure virtual network topologies using routers, switches, and firewalls - Manage node interfaces, line connections, and console access within the virtual environment - Integrate external networks to connect your virtual lab with physical devices and the internet - Automate lab deployment and configuration tasks using the CML2 REST API - Troubleshoot common connectivity and performance issues within simulated network environments You will start with key definitions and initial setup steps before moving on to hands-on topology design and interactive configuration tasks. The course wraps up with advanced integration techniques, including external connectivity and basic automation. This course is designed for aspiring network engineers, systems administrators, and IT students who want to build virtual lab environments. No prior experience with network simulation tools is required, though a basic understanding of networking concepts is helpful.
