Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
Description
Display information about Border Gateway Protocol (BGP) route flap damping
parameters.

—(Optional) Perform this operation on all logical
systems or on a particular logical system.
Additional Information
In the output from this command, figure-of-merit values correlate to the probability of
future instability of a routing device. Routes with higher figure-of-merit values are
suppressed for longer periods of time. The figure-of-merit value decays exponentially
over time. A figure-of-merit value of zero is assigned to each new route. The value is
increased each time the route is withdrawn or readvertised, or when one of its path
attributes changes.

Output Fields
Table 276 on page 2151 describes the output fields for the
show policy damping
command.
Output fields are listed in the approximate order in which they appear.

Field Description
Field Name
Decay half-life, in minutes. The value represents the period during which the accumulated
figure-of-merit value is reduced by half if the route remains stable. If a route has flapped, but then
becomes stable, the figure-of-merit value for the route decays exponentially. For example, for a route
with a figure-of-merit value of 1500, if no incidents occur, its figure-of-merit value is reduced to 750
after 15 minutes and to 375 after another 15 minutes.
