http://www.boson.com/AboutNetSim.html I am in the 2nd quarter of my 4 quarter long CCNA class. We are in the 3rd week of working with routers. I don't have access to a router in the real world. I am a lowly computer operator. I might be able to sweet talk the manager of tech services into lending me an extra router for a bit. That is a real possibility. I understand that this NETSIM thing would simulate an entire network including switches and routers and bridges and everything. Thing is... it is not cheap. $175!!! that is for the basic version! My wife is like, 'Well we can afford it. If you need it just get it.'. But I am seriously questioning wether I do need it or not. I am on the fence. Any suggestions?
