Should I use a mainline and technology train image?

You'll find the technology train images to contain the newest features but it could also contain the most bugs. We recommend Mainline over technology train if you is interested on stability without the need of new features. Please see the Cisco IOS Versions and naming for more information.

Recommended Images

We really recommend using c3640, c3660, c3725, c3745 and c7200 IOS imageslisted below, they have PR Oven To is the most stable in GNS3 provided you use the right amount of RAM and idle-pc value.
