How to connect 3 routers?

Question

Computer networks

I already wrote a question on this topic, they helped with writing static routing. When I added 3 routers to the network, I had problems connecting them to each other.

From subnet "A" to subnet "B" packets go without problems.
Routers 192.168.2.1 and 192.168.2.2 are connected via LAN2.

Please tell me how to connect 3 routers 192.168.2.3 to them correctly and correctly register IP addresses.

Not understanding due to the fact that it is necessary to register IP from 1 to another and in the opposite direction, that is, let's say I don't understand how to register from 192.168.2.1 to 192.168.2.3 and in the opposite direction, can someone please explain?

Answer 1

Your scheme won't work. If you only change the IP addresses and the new router is connected to the old routers with addresses from another network. Or put a switch between three routers and one cable from each router to the switch, so you can connect them into one network.
PS I have a feeling that you don't know how IP works and what these numbers are and why exactly they and not others :) It's better to start learning again and gradually, and not from the middle.

Answer 2

you need to register static routes between subnets

Answer 3

I have a smaller scheme - how to make both subnets friends
