l reuse: specifies the threshold for releasing routes from being suppressed. When the penalty
is smaller than the threshold, the suppressed routes are reused.
l suppress: specifies the threshold for suppressing routes. The value must be greater than the
value of reuse. When the penalty is greater than the threshold, the routes are suppressed.
l ceiling: specifies the ceiling value of the threshold. The value must be greater than the value
of suppress.
l route-policy route-policy-name: specifies the routing policy. The configuration is applicable
to the routes that meet certain matching conditions.

9.7.3 Checking the Configuration
After MBGP route dampening is configured, you can check information about MBGP dampened
routes, configuration parameters, and statistics of MBGP route flapping.
Prerequisites
The configurations of MBGP route dampening are complete.
Procedure
l Run the display bgp multicast routing-table dampened command to check MBGP
dampened routes.
l Run the display bgp multicast routing-table dampening parameter command to check
MBGP route dampening parameters.
l Run the display bgp multicast routing-table flap-info [ network-address [ mask [ longer-
match ] | mask-length [ longer-match ] ] | as-path-filter { as-path-filter-number | as-path-
filter-name } | regular-expression as-regular-expression ]command to check the statistics
of MBGP route flapping.

9.8 Maintaining MBGP
Maintaining MBGP involves resetting MBGP connections and clearing MBGP statistics.
9.8.1 Resetting MBGP Connection
You can choose to reset MBGP in GR mode. Resetting an MBGP connection will interrupt the
MBGP peer relationship.
Context
CAUTION
The MBGP peer relationship is deleted after you reset MBGP connections with the reset bgp
multicast command. So, confirm the action before you use the command.
