GNS3 Dream Fulfilled
Lo and behold - my GNS3 Lab Dream has been mostly fulfilled! As I was blogging on Network World, one of the readers posted this link:
It's a massive GNS3 support/lab forum where many people have created lab topologies for existing books/scenarios out on the market! Much less work than creating labs manually (my initial idea). I've redirected GNS3Labs.com to this site - great stuff!
Okay...I have to admit...I'm a little bummed this is already out there. It feels a little like I jumped out of my chair saying, "wouldn't it be great if there was a device that could excite water molecules to cause friction and heat up food?!?!" Ehhh... I'm sure I'll get over it - I'm really excited to see this site in play!
UPDATE: In surfing through the site, they even have a .NET file for the CCIE topology I created for CBTNuggets! Awesome!

I have tested gns3 a little bit (not more then adding two switches) and it gave some real performance issues with my laptop.
I wonder what kind of specs your computer must have to run that CCIE topology.

I thought the idea behind GNS3Labs.com was to provide a web site where users who might not have access to Cisco IOS images could login and have ready access to GNS3 with a variety of IOS images to use.

@chiel
The secret is to get the right PC Idle value for the devices you are simulating and when you get it right the resources consumption will decrease dramaticly.

@Chuck - That was my original dream, which was heavily modified once I spoke with a few people on the processing power that would be required to make this happen. Then I just decided to make GNS3Labs a "lab repository" site.

I use it for my DMVPN labs and any other routing.
When and if switches will be implemented will make it worth while.

Hey Jeremy!
Just wanted to know if you could provide more labs and exercises as well, your first one really helped me with some topics.
thanks

instead of gns3, which is great for beginners, post cbtnugget labs in dynamips original .net. I have offered my services and I can create labs quite easily. the good thing with dynamips labs is they can be easily used/edited by anyone, gns3 is difficult to import and share between users, I have done it but in depth knowledge of how the .net is setup is needed.
JC, send you lab topology, intitial cnfgs and final cnfgs my way and I can package in .net and show you how easy it can be done.
