If you looking for network simulator for Cisco equipment it's been my exper=
ience that Boson (www.boson.com) has best network simulator for Cisco equip=
ment. 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.

You can do some switching by stuffing a virtual NM-16ESW into your faketast=
ic 3660 in Dynamips. Then there are the built-in frame-relay and ethernet s=
witches you could dump into the mix as well.
