penalty value reaches the suppress limit, the route will be suppressed. When the
half-life-time reaches, the penalty value is reduced to half of its value. Once the

route can be suppressed for the maximal suppress time.
To configure the route flap dampening of the BGP, execute the following
operations in the BGP configuration mode:
Command Function
