dampening (BGP)
Sets dampening parameters for the route.
Synopsis dampening {half-life reuse suppress max-suppress-time | route-map route-map}
no dampening
Operands half-life Number of minutes after which the route penalty becomes half its value.
Range is from 1 through 45. Default is 15.
reuse Minimum penalty below which the route becomes usable again. Range is
from 1 through 20000. Default is 750.
suppress Maximum penalty above which the route is suppressed by the device.
Range is from 1 through 20000. Default is 2000.
max-suppress-time Maximum number of minutes a route can be suppressed by the device.
route-map Enables selection of dampening values established in a route map by
means of the route-map command.
route-map Name of the configured route map.
Defaults None
Command Modes BGP address-family IPv4 unicast configuration mode
Description Use this command to set dampening parameters for a route in BGP address-family mode.
Usage Guidelines Use dampening without operands to set default values for all dampening parameters.
To use the dampening values established in a route map, configure the route map first, and then
enter route-map followed by the name of the configured route map.
A full range of dampening values (half-life, reuse, suppress, max-suppress-time) can also be set by
means of the set as-path prepend command.
Use the no form of this command to disable dampening.
Examples To enable default dampening as an address-family function:
switch(config)# rbridge-id 10
switch(config-rbridge-id-10)# router bgp
switch(config-bgp-router)# address-family ipv4 unicast
switch(config-bgp-ipv4u)# dampening
To change the all dampening values as an address-family function:
switch(config)# rbridge-id 10
switch(config-rbridge-id-10)# router bgp
switch(config-bgp-router)# address-family ipv4 unicast
switch(config-bgp-ipv4u)# dampening 20 200 2500 40
To apply the dampening half-life established in a route map, configure the route map and then use
the set dampening command:
switch(config)# rbridge-id 10
switch(config-rbridge-id-10)# route-map myroutemap permit 1
switch(config-route-map-myroutemap/permit/1)# set dampening 20
