How to set up 2 providers on Mikrotik?

Question

Computer networks

Hello.
Good people, I have such a question, there is: Mikrotik CCR1009-8G-1S as a router, there is also Mikrotik CRS125-24G-1S as a switch and 2 providers, we will conditionally call them (P1 and P2), at the moment I use P1, and P2 should work as a backup Internet channel, that is, if the connection is broken P1 Mikrotik CCR1009-8G-1S should automatically change the Internet channel to P2.
