Impact on the System

Routes cannot be learnt, and traffic forwarding is affected.

Possible Causes

The size of the LSPs originated from IS-IS on the source is larger than the size of the local buffer for originating LSPs.

Procedure

  1. Run the display current-configuration configuration isis command on the local device to check the size of LSPs. If the command output does not contain the LSP size, the default LSP size is used. Run the display default-parameter isis command to check the LSP-Receive-Length field.
  2. Find the source from which the LSPs are originated based on the lsp-id field value in the trap output. Run the display current-configuration configuration isis command to check the size of the LSPs on the source . If the command output does not contain the LSP size, the default LSP size is used. Run the display default-parameter isis command to check the LSP-Originate-Length field.
  3. Check whether the value obtained in Step 1 is smaller than that obtained in Step 2.

    • If so, go to Step 4.

    • If not, go to Step 7.

  4. Perform the following steps as required:

    • If the size of the local receiving buffer for LSPs is a default value, go to Step 5.
    • If the size of LSPs originated from the source is a default value, go to Step 6.

  5. Run the lsp-length originate max-size command in the IS-IS process of the source to modify the size of LSPs, and ensure that the size is smaller than or equal to the size of the local receiving buffer. Then, check whether the trap is cleared.

    • If so, go to Step 8.

    • If not, go to Step 7.

  6. Run the lsp-length receive max-size command in the IS-IS process to modify the size of the LSPs that can be received by the local , and ensure that the size is greater than or equal to the size of LSPs sent from the source . Then, check whether the trap is cleared.

    • If so, go to Step 8.

    • If not, go to Step 7.

  7. Collect the trap information, log information, and configuration of the , and contact technical support personnel technical support personnel.
  8. End.
