How to connect computers in one network using 3 routers?

Question

Computer networks

You need to create a network so that every computer and router can ping to any device. I drew a picture:

I can’t figure out what and to whom to assign (IP, gateway). It turned out to make access from left to right, it does not work back. If you can, explain what a computer connected to the WAN means and how to assign IPs.

Answer 1

Take the main router (into which the "Internet is plugged"). Set it up so that it works (for example, distribute addresses 192.168.0.{100..254} via dhcp.
Take a second router. Turn off dhcp. Register a static address on it on the internal network outside the dhcp range (so that the router does not look for this later).
Take the third one, repeat.
On all three, configure wifi as needed.
Then you hook this whole garland with LAN (!) Ports between each other. Use the WAN port only on the "main" router. Do not make a ring in any case (if STP is not supported by routers, but this is unlikely), it is better to connect both "secondary" routers to the first one (so that the "main" one is, as it were, in the center of the whole garland), if the traffic really goes to the Internet.
Well, then you connect everything you need via wifi to any router or to the LAN ports of any router.

Answer 2

l2p : Let's assume for a moment that you have a Cisco.
In this case, as soon as you configure the IP, you should have a connection between the middle machine in the figure and the side ones.
It remains only on the left router to add the route through the middle to the right
(conf) # ip route 10.1.1.1 255.255.255.0 10.2.2.2
and similarly - on the right router through the middle to the left
(conf) # ip route 10.3.3.3 255.255.255.0 10.2. 2.2
show those routing tables that you have now.

Answer 3

1 роутер - с интрентом в WAN. На нем поднимаете DHCP. Из LAN первого тянем провод в WAN(!) второго.
На втором в настройках WAN указываем Статический IP. Из LAN второго тянем провод в WAN(!) третьего.
На третьем снова ставим в настройках WAN порта - Статический ip. естественно на 2 и 3 нужно указать эти адреса.
Также на 1, 2 нужно указать параметр - " Отвечать на запросы из WAN". Может быть написано "на ping запросы"
У вас ошибка - в WAN хосты не коннектят
