Fixed limit—Log a message when IS-IS reaches the maximum the configured maximum. IS-IS does
not accept any more redistributed routes. You can optionally configure a threshold percentage of the
maximum where IS-IS will log a warning when that threshold is passed.
Warning only—Log a warning only when IS-IS reaches the maximum. IS-IS continues to accept
redistributed routes.
Withdraw—Start the timeout period when IS-IS reaches the maximum. After the timeout period,
IS-IS requests all redistributed routes if the current number of redistributed routes is less than the
maximum limit. If the current number of redistributed routes is at the maximum limit, IS-IS
withdraws all redistributed routes. You must clear this condition before IS-IS accepts more
redistributed routes.
You can optionally configure the timeout period.
