I'm studying for my CCNP (passed the switch exam) and I'm using GNS3 for the route exam which can cause me headaches with the idelpc option from time. Anyway I also have some routers sitting there doing nothing that work gave me for my studies, but I'm finding I don't need them due to GNS3, but feel it's a waste. Did you use real kit for your studies?
2 x 2620s
1 x 2621
It would be useful to use 1 router as a FR switch so should I buy a NM-8A/S 8-port Serial Module giving me 8 serial ports and use it in a 2620 or I see you can buy a Cisco 2520 FR switch for a tiny bit more giving my 5 serial ports.
To add to great answers by John and Aninda, I do admit I use Dynamips/Dynagen all the time (and may God bless the guy who wrote it - anyone irked at the related licensing issues please contact me via private message to discuss this privately ). I have not been using GNS3, though. I know it is much more flexible and convenient than writing topology scripts for Dynagen. At the same time, GNS3 does not seem to be as stable as Dynamips/Dynagen combination and for some inexplicable reason, GNS3 has always been more heavy on my CPU than Dynamips/Dynagen combination. Using Dynamips/Dynagen with recent 2691 images has always worked like a charm for me - very stable, feature-rich, relatively low CPU, and regarding the idlepc value, once you get a good value for a particular image, there is no need to re-evaluate it.
So I would personally suggest learning how to use the Dynagen, and stick with it, even if it is less convenient than the GUI-driven GNS3.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
