I studied the Cisco networking materials 5-10 years ago but never actually got round to taking the tests. Dynamips was a router hardware emulator for the 1700, 2600, 3600, 3700, and 7200 hardware platforms that booted up actual Cisco IOS images.
With GNS3, it was possible to set up complex network topologies of dynamips routers that would have cost thousands of dollars in real hardware without losing any of the realism as these were essentially virtualised routers.
I haven't kept up with the progress here but Cisco certification may not be the best example.
