So, when studying for certs or testing out some design, I feel it's an inefficient use my time to go through and address links, set up IGPs, put appropriate address families on interfaces, etc. So, I built a set of scripts that builds some of the basics for me.

It's not bullet proof and the documentation assumes knowledge of GNS3, Olive, and some Perl, but if you have a bit of time to play with it, I think you'll be able to figure it out.
