I came across GNS3Vault by accident and thought I would pass it along. I’ve been doing these labs for fun at lunch or in the afternoon on a slow day and have been enjoying them. I’ve learned some new commands and have been turning up the debug output to see how everything interacts. It’s nice because there aren’t many routers involved so you can usually isolate the communication of whatever process you are configuring.
The only complaint I have for some of the labs is that there is so much of what I consider pre-configuration. I don’t want to have to play with adding IP addresses to interfaces. If you’re going to make me, at least give me some random subnet masks to make it interesting.
My hat is off to Rene for such a great resource.
