Does somebody know how Tier-1 networks implement route damping ?
Here is the document:
I can't speak for any large networks, but I will say that you need to adjust a portion of that configuration to actually achieve dampening of /24s and longer. In: route-map graded-flap-damping permit 20 match ip address prefix-list min24 set damp 30 750 3000 60 you will need to change the numbers in the final line, as there is a fundamental equation that needs to be followed: 2x(max-suppress/half-life) must be greater than (suppress/reuse). So you'll need to increase either the max-suppress (60) or the reuse (60), or decrease the half-life (30) or the suppress (750). Pete -- Peter J.
