Compatibility and hardware/feature constraints

Network engineers and students preparing for advanced Cisco certifications (like the CCIE) often face a major hurdle: building a realistic, high-performance lab environment without spending thousands of dollars on physical hardware. While original emulation tools like Dynamips revolutionized CCNA prep by running real Cisco IOS images, they struggled heavily with Layer 2 (switching) features. Can’t copy the link right now
