ISIS/3/ISIS_ORIG_LSP_BUFF_SIZE_MISMATCH: The size of the local buffer for originating IS-IS LSPs is smaller than the size of the received LSP. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], isisPduLspId=[isisPduLspId], isisPduOriginatingBufferSize=[isisPduOriginatingBufferSize], ifIndex=[ifIndex], IfName=[IfName])


The size of received LSPs was greater than that of the local buffer where LSPs were generated.


Parameter Name Parameter Meaning


Indicates the ID of the IS-IS process.


Indicates the IS-IS level.


Indicates the index assigned by an IS-IS interface.


Indicates the index of the interface.




Indicates the size of a buffer.


Indicates the index of the interface.


Indicates the name of the interface.

Possible Causes

The size of LSPs generated on the source was greater than that of LSPs generated on the local.


  1. Identify the source where the LSP is generated based on the value of the isisPduLspId field. View the size of LSP packets generated on the source and check whether it is greater than the size of LSPs that are allowed on the local .

    • If so, go to Step 2.

    • If not, go to Step 3.

  2. Run the lsp-length originate max-size command in the IS-IS process on the source to change the size of generated LSPs to be smaller than or equal to the size of the buffer where LSPs are generated on the local .

    • If so, go to Step 4.

    • If not, go to Step 3.

  3. Contact technical support personnel technical support personnel.
  4. End.
