OSPF/6/CONFLICT_ROUTERID_INTER: OSPF Router id conflict maybe occur on inter-area. (ProcessId=[USHORT], RouterId=[IPADDR])


The router IDs of OSPF devices in different areas might conflict because external routes were constantly refreshed.


Parameter Name Parameter Meaning
ProcessId Indicates the ID of a process.
RouterId Indicates the ID of a router.

Possible Causes

The same router ID was configured for devices in different areas, causing route flapping.

This log is generated in the following scenarios:

  • Normal scenario: Device A generates a Type 5 LSA and floods it to Device B. Due to a fault, Device A restarts and reestablishes the neighbor relationship with Device B. Then, Device A receives the Type 5 LSA generated by itself from Device B. Because the router ID in the LSA conflicts with the local one, the log is generated. A large number of Type 5 LSAs may exist in the system. Therefore, this scenario is common. The log generated in this scenario requires no action.
  • Conflict scenario: The same router ID is configured for devices in different areas, causing route flapping.


  1. Run the ospf router-id router-id command to change the router ID.
  2. End.
