dampening 30 1000 2000 100 ---------------- I think this is correct since
interface should be dampened for 30 sec

The answer for your question:
dampening 30 1500 2000 100
And some outputs from a Router.
To resume the output below
1st Flap at Jul 27 00:14:58.985 penalty 1000, flap count 1
2nd Flap at Jul 27 00:15:11.125 penalty 1755, flap count 2, Diff 1st Flap &
2nd Flap almost 13s
3er Flap at Jul 27 00:15:23.614 penalty 2331, now suppressed with a reuse
intervals of 20 12
from a amount of 25 sec.

Group,
One of the task say ..3 interfcae flaps in 30 second will keep interface
participating in routing...Is this correct ?
dampening 30 1000 2000 120..
Thanks
