Command Line Reference Guide

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 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 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 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
1 to 255. The default is 60 minutes.

of a configured route map. Only match commands in the configured

Information

max-suppress-time are applied. The parameters are position-dependent; therefore, if
you configure one parameter, you must configure the parameters in the order they appear in
the command.
