• Maximum holddown time. If the route remains suppressed after the number of
minutes that you specify, BGP unsuppresses it (even if the penalty value
exceeds the threshold). This action does not change the penalty value.
• Memory limit. If the status of the route remains unchanged, either reachable
or unreachable, after the number of minutes that you specify, BGP
unsuppresses the route (if it is suppressed) and resets the penalty value and
flap count to 0.
BGP provides a default template. You can also use the BCC or Site Manager to
create a route flap dampening template and a BGP accept policy for route flap
dampening.
Using the BCC
To create a route-flap-dampening template, navigate to the global BGP prompt
and enter:
damping-template name
<name>
name
is a unique name identifying the template.
A template-specific prompt appears.
For example, the following command creates a route-flap-dampening template
named steady.
/jointfilesconvert/106988/bgp# damping-template name steady
damping-template/steady#
To define the parameters of a template you created, navigate to the
template-specific prompt and enter:
<parameter> <value>
parameter value
is one of the combinations described in Table 5-6.
