Hi, I've been stuck on this problem for days and was hoping to get some insights. I have a network configured in Cisco Packet Tracer where I have 2 separate campuses, and the 2 separate campuses are connected via Layer 3 switches to a ISP. However, for one of my campuses, I am sometimes able to ping the campus core switch and sometimes not able to. I have done some further investigation via the PDU simulation in Cisco Packet Tracer and I found out that the Destination IP Address sometimes changes to the IP address of the GigabitEthernet0/1 interface of the Core Switch, which is extremely puzzling as that interface is not connected to the campus PC distribution switches.
The PCs that are unable to ping the Core_Switch are any of the PCs under SR7A, SR7B, SR7C etc. Also, to mention, I am extremely puzzled as to why this is happening as I configured the exact same layout for my other Core_Switch and it is working flawlessly. Could both of them having connections to the Main_Core_Switch be causing some problems?
I have attached my Cisco Packet Tracer file.
Solved! Go to Solution.

Hello @floofycat
Please adjust/modify your RIP process like this on that SW:
After these modifications you should be able to ping a PC on SR7A
