Hello,
First time using the forum so please bare with me.
Im currently doing an assignment for my university, OSPF Routing. Ive not done routing before but the assignment is pretty clear on how it wants everything set up and what configurations to use (Such as IP, Subnet masks etc).
The network is made up of 4 routers conected via WAN. 1 Main router and 3 additional routers for each other site. The main router is connected to all 3 of the others but they are each only connected to the main router. Each router is connected to a switch and 2 computers.
The objective is to be able to connect computers over the different networks. The problem is that my computers are unable to ping. The IP route is showing OSPF is set up on all 4 routers and can read each network. Here is the IP route:

So far i have checked that all my network selections match up with each network's network IP, this includes the wildcard masks. I have also tried setting network to the interface IPs. One concern i do have is the physical set-up for the routers. Ive never connected serial ports and wasnt sure if the modules would affect anything but i doubt this is the issue. Unfortunately i lack the experience to identify what is likely a simple issue. Ive attached the file to this post for anyone willing to help and i thank everyone in advance.
