Usage Guidelines
The half life is the period of time, in minutes, during which the accumulated penalty of a route is
reduced by half. The range is 1 to 45 minutes, and the default is 15 minutes.
The reuse limit is the penalty value below which a route will be used again. The range is 1-20,000, and
the default is 750.
The suppress limit is the penalty value above which a route will be suppressed. The range is 1-20,000,
and the default is 2,000.
The maximum hold down time is the maximum time a route can be suppressed, no matter how
unstable it has been, as long as it no longer flaps. The range is 1-255 minutes, and the default is 4 * the
half life.
Use the following command to disable route flap dampening for BGP neighbors:
configure bgp neighbor [<ip address> | all] no-dampening
Example
The following command configures route flap dampening to the BGP neighbor at 192.168.1.22:
