2: System level 

half-life-reachable: Specifies a half-life for active routes from 1 to 45 minutes. By default, the value is 15 

minutes. 

half-life-unreachable: Specifies a half-life for suppressed routes from 1 to 45 minutes. By default, the 

value is 15 minutes. 

reuse: Specifies a reuse threshold value for suppressed routes from 1 to 20000. A suppressed route 

whose penalty value decreases under the value is reused. By default, the reuse value is 750. 

suppress: Specifies a suppression threshold from 1 to 20000. The route with a penalty value higher than 

the threshold is suppressed. The default value is 2000. 

ceiling: Specifies a ceiling penalty value from 1001 to 20000. The value must be greater than the 

suppress value. By default, the value is 16000. 

route-policy-name: Route policy name, a string of 1 to 19 characters. 

Use the dampening command to configure IPv4 MBGP route dampening.  

Use the undo dampening command to disable route dampening. 

By default, no IPv4 MBGP route dampening is configured. 

The command dampens only EBGP routes rather than IBGP routes. 

# In IPv4 MBGP address family view, configure IPv4 MBGP route dampening.
