routers connected by point to point serial connection
Lets say you have Router 1 and Router 2 connected by point to point serial connection.
Router 1 has S0 (as the name of the serial interface) and Router 2 has S1 networks. In order for the networks that are in Router 1 to communicate to Router 2 and vice versa, both S0 and S1 must belong to the same IP subnet?
If so how does that work? Im new to Routers communicating with each other. How in the world can two interfaces who are in different routers belong to the same subnet?

Yes you are corrent the two serial interfaces are in the same subnet.
A router has multiple interfaces which are all in different subnets, let say for example (keeping it simple) all it has is one serial port and one 10baseT port the two ports are in different subnets
Lan1
R1 Enet -R1 Serial_________R2 Serial-R2enet
Lan2
When the router recieves a request for an external subnet it consults it routing table and sends it out the corresponding interface.Looking for CCIE lab study partnerts, in the UK or Online.
