Default
This feature is disabled by default.
If no address family is specified, IPv4 unicast is the default.
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.
Instead of explicitly configuring the dampening parameters using the command line, you can associate
a policy using the
policy-filter
