half-life-unreach

Use this command to specify the time in seconds after which an unreachable route‘s penalty value decays to half its current value.

Syntax

half-life-unreach seconds
no half-life-unreach

Parameters

seconds Specifies the number of seconds after which an unreachable route‘s penalty value decays to half its current value. Valid values are 1 - 3600. The default value is 900.

Defaults

None.

Mode

Dampen Flap Configuration.

Usage

The dampen penalty value assigned to a route decays over time. Use the half-life-unreach command to specify a time in seconds, after which an unreachable route‘s penalty value decays to half of its current value, assuming the route remains stable and unreachable.

The half life unreach value must be less than the configured memory limit unreachable value configured using memory-limit-unreach.

The “no” form of this command resets the half life unreachable value to its default value of 900 seconds.

Example

The following example configures the half life unreach value to be 600 seconds.

System(su-config)->dampen-flap rfd1
System(su-config-dampen-flap)->half-life-unreach 600
