What is Dynamips ?

Dynamips is an emulator computer program that was written to emulate Cisco Routers and it can emulate the hardware of the Cisco series routing platforms by directly booting an actual Cisco IOS software image into the emulator. Dynamips emulates Cisco platforms 1700, 2600, 2691, 3600, 3725, 3745, and 7200.
