Long the bane of wanna be CCIE’s everywhere, routers are expensive! And there’s no way to pass the lab without routers for practice. Enter the router emulator. The Cisco 7200 Simulator doesn’t just create a simulated environment like the Boson and other programs do. This is actually emulating the processor and interfaces in a 7200. What’s cool about this is it’ll take a variety of real IOS images for the 7200 and run them without modification. Just like VMWare for a router. I’ve fiddled with it a little and it works. It’s a bit difficult to use but I understand there are various GUI setup apps being worked on to streamline the hardware configuration. Sounds like a perfect tool for testing that new BGP config.
