OSPF/4/AUTO_CHG_RTRID: OSPF automatically changes the router ID when detecting router ID conflict in the area. (ProcessId=[ProcessId], NewRouterId=[ConflictRtId], OldRouterId=[RouterId], ConflictRtrIdNum=[ConflictCount])


The system automatically changed the router ID after detecting a router ID conflict in one OSPF area.


Parameter Name Parameter Meaning
ProcessId Process ID
NewRouterId New router ID
OldRouterId Original router ID
ConflictRtrIdNum Number of router ID conflict times

Possible Causes

At least two indirectly connected routers shared the same router ID within one area. As a result, router LSAs were refreshed frequently, which led to route flapping.


  1. Run the undo ospf router-id auto-recover disable command to enable the router ID automatic recovery function. After the function is enabled, the system automatically allocates a new router ID.
  2. If the conflict persists, re-configure a router ID.
