 Cisco 3750X Duplicate IP Address
I'm currently having an issue with a 3750X switch connected to 6509E switch whereby the 3750X keeps rebooting/reloading and then producing  duplicate IP messages. I have checked all the address and could not locate anything that match. I then went on to disconnect the 3750x and for some unknow reason it continued to recieve duplicate IP address error messages but from it's own IP address. Can any one point me in the right direction to both questions. The reboots and duplicate IP's?

Answer Wiki:
The error indicates an issue with the OSPF settings. You have a duplicate router ID in OSPF. In configuration mode go to the OSPF router number and change the router ID. Router OSPF ---- Router-id ---------
