(isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], isisPduLspId=[isisPduLspId], isisPduRemoteRouterID=[isisPduRemoteRouterID], ifIndex=[ifIndex], IfName=[IfName])

Description

IS-IS received an LSP with a system ID identical to that on the local device. The lifetime of this LSP was 0.

Parameters

Parameter Name	Parameter Meaning
isisSysInstance	ID of an IS-IS process
isisSysLevelIndex	IS-IS level
isisCircIndex	Circuit IfIndex of an interface
isisCircIfIndex	Circuit IfIndex of an interface
isisPduLspId	LSP ID
isisPduRemoteRouterID	ID of the remote router
ifIndex	IfIndex of an interface
IfName	Interface name

Possible Causes

Cause 1: LSPs were not refreshed in time on the local device. Purge packets were generated and then flooded to the local device after these LSPs aged.

Cause 2: After a fault occurred during the packet transmission, packets were changed and purge packets were generated.

Cause 3: After the local device restarted, it received an LSP with a system ID identical to the one on the local device. In addition, the lifetime of the LSP was 0.

Procedure

1. Check whether the local device restarted.

If so, go to Step 4. In this case, this log message is informational only, and no action is required.
If not, go to Step 2.

2. Check whether IS-IS authentication configuration is changed on the device.

If so, go to Step 4. In this case, this log message is informational only, and no action is required.
If not, go to Step 3.
