protocols bgp <asn> address-family ipv6-unicast parameters dampening <time>

Enables or disables route dampening and sets route dampening values on the system.

set protocols bgp asn address-family ipv6-unicast parameters dampening { half-life minutes | max-suppress-time minutes | re-use penalty | start-suppress-time penalty }
delete protocols bgp asn address-family ipv6-unicast parameters dampening [ half-life | max-suppress-time | re-use | start-suppress-time ]
show protocols bgp asn address-family ipv6-unicast parameters dampening [ half-life | re-use | start-suppress-time | max-suppress-time ]

Route dampening is disabled.

asn
The number of the AS in which this router resides. The numbers range from 1 through 4294967294. The subrange, 64512 through 65534, is reserved for private AS.
half-life minutes
The time period, in minutes, after which the penalty assigned to a route because of flapping is reduced by half. The numbers range from 1 through 45. The default is 15.
max-suppress-time minutes
The maximum time, in minutes, that a route may be suppressed. The numbers range from 1 through 20000. The default is four times the half-life period.
re-use penalty
The reuse threshold. If the penalty for a flapping route is reduced below this point, the route is to be brought back into use. The numbers range from 1 through 20000. The default is 750.
start-suppress-time penalty
The route suppression threshold. If the accumulated penalty for a flapping route reaches this limit, the route is suppressed. The numbers range from 1 through 20000. The default is 2000.
