How to connect one router to another?

Question

Computer networks

Hello. I will say right away, in these matters I am 0!
I can connect to the maximum via PPPoE (since I connect to the Internet this way).
So, the task itself:
I need to connect the Internet from my router to my neighbors. I suggested the idea - to pay in half for the Internet, antenna (Wi-Fi receiver, located with us). I want to run a cable from my router to their apartment (we live in the private sector, it won’t be difficult), but now I’m thinking. How to connect the Internet in a router from a router? Also, via PPPoE, by entering the login and password from the provider, or from the router-distributor? Or what should be done?

Answer 1

PPPoE is no longer needed - the channel is created on your router.
You can connect neighbors via a switch, i.e. you will all live in the same locale together.
