Impact on the System

Link state protocol data units (LSPs) are frequently updated, and route flapping occurs.

Possible Causes

Two IS-IS routers in the topology have the same system ID.

Procedure

Modify the conflicting system ID to ensure that the system IDs of devices in the topology are unique.
Run the undo isis system-id auto-recover disable command on the device where a system ID conflict occurs to enable the device to automatically change the local system ID when a system ID conflict occurs on the network.
