Very Basics

I have a new RB450G running 4.16. I am a bit unclear as to the best method for clearing the configuration in order to build a new one, as resetting to default loads a complete config which then needs to be undone. I have ordered the book “Learning RouterBoard OS”, but perhaps someone can offer a few resources in the meantime. The Wiki is helpful but the topics are so specific to individual services and setups that I fear I’m missing the big picture. Thank you.

does:

/system reset-configuration
