Dynamips (which is under the hood of GNS3) could be used to emulate IOS switching behavior as long as what you're trying to do is supported on the routers. If you're testing standard spanning tree, Dynamips should be just fine (you'll just configure routers as bridges).
OPNET is a great network simulation tool. I've used it years ago and I was deeply impressed. They might have academic or test licenses. You might also want to consider Cisco's PacketTracer: http://www.cisco.com/web/learning/netacad/course_catalog/PacketTracer.html Some other tools are listed here: http://www.idsia.ch/~andrea/sim/simnet.html Best regards Ivan http://www.ioshints.info/about http://blog.ioshints.info/ > I'm looking for a (free) network simulator that allows me to > simulate a small network (20 switches) with different vlans > on it.
