OSPFV3/4/OSPFV3_AUTO_CHG_RTRID

Message

OSPFV3/4/OSPFV3_AUTO_CHG_RTRID: OSPFV3 automatically changes the router ID when detecting router ID conflict in the area. (ProcessId=[USHORT], NewRouterId=[STRING], OldRouterId=[STRING], ConflictRtrIdNum=[ULONG])

Description

OSPFv3 automatically changed the router ID when two or more same router IDs were detected in an area.

Parameters

Parameter Name	Parameter Meaning
ProcessId	Process ID.
NewRouterId	New router ID.
OldRouterId	Original router ID.
ConflictRtrIdNum	Number of conflict router 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 ospfv3 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.
