To apply the template to an inbound BGP routing update:

Create and name a BGP accept policy.

For instructions on creating a BGP accept policy, see “Defining a BGP Accept

Policy” on page 7-2.

An accept policy-specific prompt appears.

Modify the accept policy by entering the following commands:

action accept

route-damping enabled

route-damping-template

<name>

name

is the name of the template that you want to apply to the unstable route.

Table 5-6. Route-Flap-Dampening Template Parameters

Parameter Value/Default Meaning

cutoff-threshold Integer/2000 Specifies a maximum threshold (1 through

20,000) for the route penalty value

reuse-threshold Integer/750 Specifies a minimum threshold (1 through

20,000) for the route penalty value

reachable-decay Number of minutes/5 Specifies the number of minutes (1

through 45) that the route must remain

reachable before BGP decrements the

penalty value by half

unreachable-decay Number of minutes/15 Specifies the number of minutes (1

through 45) that the route must remain

unreachable before BGP decrements the

penalty value by half

max-hold-down Number of minutes/45 Specifies the maximum number of minutes

(1 through 60) that a route can remain

suppressed

memory-limit Number of minutes/45 Specifies the maximum number of minutes

(1 through 60) that the status of a route

can remain unchanged -- reachable or

unreachable -- before BGP resets the

penalty value and flap count to 0 and

unsuppresses the route
