bgp dampening

[pacquaviva]

Hi,

I have to check if in Cisco 7200 router there are bgp session flapping without charging the cpu and I had an idea using the bgp dampening command.

Now, if someone used it, if this command introduces cpu load.

Thank you.

Regards.

bgp route dampening is not so cpu intensive.

once the route is dampened, it depends on a simple property, the ReuseLimit, in conjunction with the HalfLife of the suppression, to begin advertising the route again.

this is not too cpu intensive to worry about, unless you had thousands of routes to dampen.
