Parameters
half-life (OPTIONAL) Enter the number of minutes after which the
Penalty is decreased. After the router assigns a Penalty of 1024

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
