Please refer to the URL, there're actually a couple of examples out there, a good reference on JUNOS would be CYMRU's. Not sure if it's updated yet.

Here's a sample.

policy-statement damping-policy {
    term 1 {
        from {
            route-filter 0.0.0.0/0 prefix-length-range /24-/32 {
                damping high-damp;
                accept;
            }
            route-filter 0.0.0.0/0 prefix-length-range /22-/23 {
                damping medium-damp;
                accept;
            }
            route-filter 0.0.0.0/0 orlonger {
                damping normal-damp;
                accept;
            }
        }
    }
}

damping high-damp {
    half-life 30;
    reuse 820;
    suppress 3000;
    max-suppress 60;
}
damping medium-damp {
    half-life 15;
    reuse 750;
    suppress 3000;
    max-suppress 45;
}
damping normal-damp {
    half-life 10;
    reuse 1500;
    suppress 3000;
    max-suppress 30;
}
damping no-damp {
    disable;
}

How do you guys do else in JUNOS policy.. like what if I want 116.203.0/16
orlonger damping high and rest normal. How you are going to use it.



Damping: high

Damping: normal



policy-statement damp {

       term 1 {

           from {

               route-filter 116.203.0.0/16 orlonger damping high;

           }

       }

Else normal

   }
