Free Cisco Emulator

At work and occasionally at home I feel the need to try out a bit of Cisco config. Of course, building a lab using multiple physical devices can be a bit of a drag. Luckily, the good old Dynamips tool and the GUI wrapper, GNS3 save a lot of kit lugging.

For a foray into what you can do, delve into the CCIE blog pages here or go download the beast yourself and have a play.
