If you looking for network simulator for Cisco equipment it's been my experience that Boson (www.boson.com) has best network simulator for Cisco equipment. It behaves and process information the way real Cisco equipment does. I've tried GS3, it great for routing situations but lacks in simulating switches.

Then there are the built-in frame-relay and ethernet switches you could dump into the mix as well. -Ryan On Mon, Jan 17, 2011 at 10:23 AM, Brandon Kim <brandon....@brandontek.com>wrote: > > James: > > I've been resisting GNS3 for the longest time, because I like real > equipment and to get my hands a little dirty. > But for the purpose of simulation, GNS3 helped me identify a BGP issue > last week.
