I have a set up where 4 routers are connected sequentially in Cisco Packet Tracker, however the RIP isn't working and I don't know why.

I have attached the file

Hello,

RIP is not the problem, you have that configured correctly. The problem is that your serial interface have duplicate IP addresses. I changed the addressing, find attached the working file...
