Do you have startup config for new labs?

Hi,

I'm getting bored lately with setting up a new lab and assigning IP addresses with no sh commands. It takes some time and I do it so often that it bothers me.

Do you create one big lab which you copy and apply another config on it or do you export startup config?

I don't think that copying labs from videos is a good idea but better understand what a person did and apply it on your own topology, right?

I appreciate every tip.
