threshold—Percent of maximum prefixes that will
•
trigger a warning message.
warning-only—Logs an warning message when
•
the maximum number of prefixes is exceeded.
withdraw—Withdraws all redistributed routes.
•
Optionally tries to retrieve the redistributed
routes. The num-retries range is from 1 to 12. The
timeout is 60 to 600 seconds. The default is 300
seconds. Use clear isis redistribution if all routes
are withdrawn.
