Route Policy Command Reference
Route Policy Damping Commands
damping
Syntax [no] damping name
Context config>router>policy-options
Description This command creates a context to configure a route damping profile to use in route policy entries.
If damping is enabled and the route policy does not specify a damping profile, the default damping
profile is used. This default profile is always present and consists of the following parameters:
Half-life: 15 m
Max-suppress: 60 m
Suppress-threshold: 3000
Reuse-threshold: 750
The no form of the command deletes the named route damping profile and uses the default damping
profile.
Default no damping
Parameters name — the damping profile name. Allowed values are any string up to 32 characters long
half-life
Syntax half-life minutes
no half-life
Context config>router>policy-options>damping
Description This command configures the half-life value for the route damping profile.
The half-life value is the time, expressed in minutes, required for a route to remain stable in order for
the Figure of Merit (FoM) value to be reduced by one half; for example, if the half-life value is 6 and
the route remains stable for 6 min, then the new FoM value is 3. After another 3 min pass and the route
remains stable, the new FoM value is 1.5.
When the FoM value falls below the reuse threshold, the route is once again considered valid and can
be reused or included in route advertisements.
The no form of the command removes the half-life parameter from the damping profile and uses the
value from the default profile.
