OSPF/4/AUTO_CHG_RTRID

Message

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

Description

OSPF automatically changed the router ID when two or more same IDs were detected for a switch in an area.

Parameters

Parameter Name	Parameter Meaning
ProcessId	Process ID
NewRouterId	New ID for a switch
OldRouterId	Original ID for a switch
ConflictRtrIdNum	Number of conflict switch IDs

Possible Causes

The same router ID was configured for at least two indirectly connected routers within one area, which caused the router lSA to be refreshed frequently. As a result, route flapping occurred.

Procedure

If the undo ospf router-id auto-recover disable command is enabled by default, the system will be automatically restored after two or more same router IDs are detected.
If the system cannot be restored automatically, change a router ID manually.
