Binary package “dynamips” in ubuntu lucid
Cisco 7200/3600/3725/3745/2600/1700 Router Emulator
Dynamips emulates Cisco 7200/3600/
PC. You can use dynamips to create labs. It uses IOS Images (which are not
part of this package). Of course, this emulator cannot replace a real router.
It is simply a complementary tool to real labs for administrators of Cisco
networks or people wanting to pass their CCNA/CCNP/CCIE exams. For a Command
Line Interface for dynamips see dynagen or gns3 package.
