Route dampening is a method that determine
whether a route is suppressed from being advertised because it is flapping.
Route dampening can reduce the number of times routers are forced
to reconverge due to routes flapping. Settings include: Profile
Name—Enter a name to identify the profile. Enable—Activate the profile. Cutoff—Specify a route withdrawal
threshold above which a route advertisement is suppressed (range
is 0.0-1,000.0; default is 1.25). Reuse—Specify a route withdrawal threshold
below which a suppressed route is used again (range is 0.0-1,000.0;
default is 5). Max. Hold Time—Specify the maximum
length of time, in seconds, that a route can be suppressed, regardless
of how unstable it has been (range is 0-3,600; default is 900). Decay Half Life Reachable—Specify
the length of time, in seconds, after which a route’s stability metric
is halved if the firewall considers the route is reachable (range
is 0-3,600; default is 300). Decay Half Life Unreachable—Specify
the length of time, in seconds, after which a route’s stability metric
is halved if the firewall considers the route is unreachable (range
is 0-3,600; default is 300).
