Collecting base configs

Hello! I am working on a tool that works with device configurations, to look for configuration drift, generate device specific configurations, etc.

My tool should work for any configuration. To that end, I would like to collect base configurations of all kinds, so I can ensure my tool works appropriately.

I would really appreciate it if any of you could provide some base configurations for your environment, so I can use them to test my tool.

I'm especially interested in layer 3 device configurations, and configurations that have a different style than Cisco (Juniper, HP, etc).

Thanks in advance for any help you can provide!
