Table 4-51 explains the output fields.
Table 4-51: show ip bgp dampening parameters output details
Field | Description |
|---|
Dampening Control Block(s) | Flap damping reduces the number of update messages by marking routes as ineligible for selection as the active or preferable route. |
Reachability Half-Life time | Number of minutes after which an arbitrary value is halved if a route stays stable. |
Reuse penalty | Reuse threshold—Arbitrary value below which a suppressed route can be used again. |
Suppress penalty | Cutoff (suppression) threshold—Arbitrary value above which a route can no longer be used or included in advertisements. |
Max suppress time | Maximum hold-down time for a route, in minutes. |
Un-reachability Half-Life time | Number of minutes after which an arbitrary value is not halved if a route stays stable. |
Max penalty (ceil) | Maximum penalty corresponds to the time it would take max-suppress to decay and reach the reuse level (ceil). |
Min penalty (floor) | Maximum penalty corresponds to the time it would take max-suppress to decay and reach the reuse level (floor). |
