ISIS/6/RCV_OWN_PURGED_LSP

Message

ISIS/6/RCV_OWN_PURGED_LSP:ISIS [USHORT] received an own purged LSP. (Level=[USHORT], PduLspId=[STRING], Interface=[STRING], NbrSystem=[STRING], SrcSystem=[STRING], SrcDynName=[STRING], SrcNbrSystem=[STRING])

Description

The IS-IS system received an LSP with Remaining Time 0 (purged LSP) from another system, and the LSP was locally generated.

Parameters

Parameter Name	Parameter Meaning
[process-id]	Indicates the IS-IS process ID.
Level	Indicates the IS-IS level.
PduLspId	Indicates the ID of the purged LSP.
Interface	Indicates the interface that receives the purged LSP.
NbrSystem	Indicates the system ID of a neighbor.
SrcSystem	Indicates the system ID of the device that sends the purged LSP.
SrcDynName	Indicates the dynamic hostname of the device that sends the purged LSP.
SrcNbrSystem	Indicates the neighbor System ID of the device that sends the purged LSP.

Possible Causes

Cause 1: The local device did not update local LSPs in time. As a result, a locally generated LSP aged and was flooded back.
Cause 2: The LSP was modified because of a failure, such as a transmission failure. As a result, the LSP became a purged LSP.
Cause 3: The local device restarted, or the IS-IS process was reset. As a result, the local device received the purged LSP that was locally generated.

Procedure

Check whether the device restarted.
- If the device restarted, this log message is informational only and no action is required.
- If the device did not restart, go to Step 2.
Check whether SrcSystem is available in the log.
- If SrcSystem is available, check the system ID of the device that sends the purged LSP and go to Step 4.
- If SrcSystem is unavailable, go to Step 3.
Check NbrSystem in the log, download the log from the neighbor, and check whether the purged LSP was sent by the neighbor.
- If the purged LPS was sent by the neighbor, go to Step 4.
- If the purged LPS was not sent by the neighbor, go to Step 5.
Check whether the purged LSP has been deleted from the device that sent it.
- If the purged LSP has been deleted from the device that sent it, this log message is informational only and no action is required.
- If the purged LSP has not been deleted from the device that sent it, go to Step 5.
Locate the device that sends the purged LSP and go to Step 4.
Collect log information and configuration information, and then contact technical support personnel.
End.
