I'm labbing up bgp dampening and had a question.
According to the doc cd and to BGP Design and Implementation there is a
formula where
Max-suppress-penalty=reuse-limit*2(max suppress time/half-life)
with the defaults that IOS assigns this should be
bgp dampening 15 750 2000 60
where 15=half-life, 750=reuse-limit, and 60=max-suppress-time
and according to the formulat max-suppress-penalty=6000
Now I entered bgp dampening into my old 12.0 router (maybe the defaults were
different a while back?)
I was able to get the penalty to pass 6000, and while the penalty was at
6500 the suppress time was still only at 45 minutes
So what's the deal? Is this formula wrong? Are the defaults wrong? Am I
wrong? :)
TIA!
Lanny
