I've just met a few friends from college who are in the networking field and they seem to think that Cisco have an official program which allows us to configure routers and switches to emulator an envoirment before implementations, they could not remember the name but said is was like Viso (drag and drop)
I've never heard of such a thing apart from Packet Tracer which is limited and GNS3 which I guess is not official?
I m missing something here or is there application out there which can be purchased or is free?
