Hi @Visauk47 

 

In your topology, each lan should have a different network, you cannot have the same network, with the same mask on 4 different LANs.
What you can do is have 4 different networks with mask 28 or divide the network into 4 different networks with mask 30.

as @luis_cordova  said, you cant assign the same network in your four routers.

 

 

 

Looks a exemple below how to address it:

 

Between R1 and R2:

172.25.25.0/30  -  R1: 172.25.25.1/30 / R2: 172.25.25.2/30

Between R2 and R3:

172.25.25.4/30  - R2: 172.25.25.5/30  / R3: 172.25.25.6/30

Between R3 and R4:

172.25.25.8/30 - R3: 172.25.25.9/30 / R4: 172.25.25.10/30

 

Hope that it can help you.

 

Regards,
