Parameters
half-life (OPTIONAL) Enter the number of minutes after which the
Penalty is decreased. After the router assigns a Penalty of
1024 to a route, the Penalty is decreased by half after the
half-life period expires. The range is from 1 to 45. The default
is 15 minutes.
reuse (OPTIONAL) Enter a number as the reuse value, which is
compared to the flapping route’s Penalty value. If the Penalty
value is less than the reuse value, the flapping route is once
again advertised (or no longer suppressed). The range is from
1 to 20000. The default is 750.
suppress (OPTIONAL) Enter a number as the suppress value, which is
compared to the flapping route’s Penalty value. If the Penalty
value is greater than the suppress value, the flapping route is
no longer advertised (that is, it is suppressed). The range is
from 1 to 20000. The default is 2000.
max-suppress-
time
(OPTIONAL) Enter the maximum number of minutes a route
can be suppressed. The default is four times the half-life
value. The range is from 1 to 255. The default is 60 minutes.

Usage
Information
If you enter the bgp dampening command, the default values for half-life,
reuse, suppress, and max-suppress-time are applied. The parameters are
position-dependent; therefore, if you configure one parameter, configure the
parameters in the order they appear in the CLI.
