Trying to understand how routers know how to talk to other router?

So for router A to see every thing and forward the data to all devices , must be on the same subnet and DHCP turn off on the router B so there no duplication of IP addresses or other subet. And router B used has switch.

No, RouterA only needs to know how to get to the 192.168.1.0/24 network, you can achieve this by adding a static route as I mentioned in a previous reply:

I'm confused here of what you are saying. Can you elaborate on this.

The router should have an option to add a route manually, the route will be something like:

Code:

  Network       Subnet Mask      Next Hop       Cost
192.168.1.0    255.255.255.0   192.168.0.254     1

Which part of this are you having trouble with ?

I don't see Network , Next Hop or cost in any of my routers.

What router are you using? Are you using Cisco?

You don't see any next hop or cost in any of your routers.

You have access to your router?

And what is static route?

Well, static is a manually defined route. Opposite of this is a dynamic route, which is automatically learned by routing protocols.

No I don't see any of this.

This is home use router . May be that why .

Maybe you could tell us the model, then we can find the manual and advise you where to add the static route, maybe even some screen-shots.

Probably they have a different name. The router has two sides (as it was already discussed), the local network (or subnet), this is the one you use personally, and the outer side (called wan).
Inside you will only see the first hop (that is your router), sometimes it is called gateway. on wan you can see the next hop, the gateway you got from your ISP, and the router will send all the packages to that ip. The following steps (next hops) cannot be visible from your subnet. If you want to trace your package you can use the command traceroute.
