Create initial router configurations from dynagen topology

I've always considered building (almost identical) initial router configurations a waste of time, more so when I had to enter them manually, enabling interfaces, configuring IP addresses and Frame Relay subinterfaces on the fly … as well as entering dozens of commands that I feel should be present in every router configuration.

When I finally had enough, I've stopped my non-critical lab tests for a few weeks (that's why there's still no answer on the very good question whether the NBAR started by NAT is of any use) and wrote configMaker: a PERL script that parses dynagen lab topology and produces initial router configurations based on a template file that you can adjust to your own needs.
