This command specifies the decay memory limit for unreachable routes.
time-seconds | Specifies the number of seconds for the decay memory limit for unreachable routes. Valid values are 0 - 3600. The default value is 1800. |
None.
Dampen Flap Configuration.
The memory limit timers are used by route flap dampening for internal calculations. Half-life timers must be configured to a value less than the corresponding reachable or unreachable memory limit timer. The memory-limit-unreach command specifies the maximum time in seconds any memory of a previous instability is retained, given the route state is both unchanged and unreachable.
The “no” form of this command resets the memory limit unreachable value to the default value of 1800.
The following example configures the keep-history value to be 1600 seconds.
System(su-config)->dampen-flap rfd1 System(su-config-dampen-flap)->keep-history 1600
