DRAG DROP
Drag the BGP route dampening configuration parameter on the left to match the correct description on the right.
Explanation:
The amount of time for the penalty to decrease to one-half of its current value – 60
Suppress a route when its penalty exceeds this value – 2400
If a flapping route penalty decreases and falls below this value , the route is unsuppressed – 600
The maximum time a route can be suppressed – 240
Configuring BGP Route Dampening
Perform this task to configure and monitor BGP route dampening.
1. configure
2. router bgp as-number
3. address-family { ipv4 | ipv6 } unicast
4. bgp dampening [ half-life [ reuse suppress max-suppress-time ] | route-policy route-policy-name ]
5. Do one of the following:
end
commit
BGP dampening parameters:
– half-life: Decay time in which the penalty is halved
– suppress: Value when the route starts dampening
– reuse: Value when the dampened route is reused
– max-suppress-time: Maximum time to suppress the route
Default values that are used by most SPs:
– half-life: 15 minutes
– suppress: 2000
– reuse: 750
– max-suppress-time: 60 minutes (4x half-life)
