netstat -rn meaning in linux?

[networkloser]

I read the UNIX and LINUX system admin handbook about this topic but I'm not yet clear about it.
I'm wondering what's the real answer to this? And what information is it really telling?
I mean some say it's a kernel routing table and it confuses me.
Can you truly make me understand this stuff?

It will list interfaces that are active with their MAC addresses and then it lists current active routes and any persistent routes.
