ISIS/6/IS_FREQUENT_CALCULATE_DELAY:ISIS-INFO: The statistics about LSP update, calculation, and flooding suppression times were recorded. (InstanceId =[InstanceId], Level =[Level], SuppressLSPstoGenerateCount=[generationLSPCount], SuppressLSPstoCalculateCount=[processLSPCount], SuppressLSPstoFloodCount=[floodLSPCount], LogPeriod = [time] )

Timers were set in the system view to delay LSP updates and flooding and LSP-triggered route calculations.


  1. Check whether any of the following inequalities is met:

    SuppressLSPstoGenerateCount > Number of local LSPs x 1800

    SuppressLSPstoCalculateCount > Number of LSPs in the LSDB x 1800

    SuppressLSPstoFloodCount > Number of LSPs in the LSDB x 1800

    • If any of the preceding inequalities is met, go to Step 2.

    • If none of the preceding inequalities is met, go to Step 3.

  2. Reduce the corresponding timer and check whether the problem is resolved.

    • If the problem is resolved, go to Step 3.

    • If the problem persists, go to Step 4.
