If you use the single subnet method, then you don't need to worry about RIP or routing tables or any of that.
You could make them all x.x.0.x
disable dhcp on the routers
static assign each a static ip x.x.0.1 and x.x.0.2
On the left side of the network you would list its local gateway for internet access for the server and two workstations.
Same on the right side for the server and workstation.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
