I saw this issue pop up again. The duplicate router ID thing caught me. We've got a main tower that has a vlan to a dozen other sites, each running an MT with OSPF. Each vlan has a ptp ospf interface, not broadcast, with a unique /30 public IP space. We only run one instance of OSPF on our main tower router, with only one router ID.
I'm thinking maybe the one router ID across all the vlans is causing the issue? Functionally, everything is working fine. But our logs are blowing up with the "Discarding packet: locally originated" error.
