Is there a way of fault finding with ospf error "Discarding packet: locally originated src address = XX.XXX.XX.XX"
this occurs every few mins?
Other common causes:
* Multiple neighbors has the same router-id - Checked OSPF Neighbours and no duplicates!
* Actual layer2 loop in the network - How do you check for Layer2 loops
* If switch is used in between, bad switch may acts as hub, sending multicast packet back to the port the packet was received from. The discarded packets are coming interfaces not going through a switch !
