Configuring route flap dampening
Removing route dampening from a route
You can un-suppress routes by removing route flap dampening from the routes. The Layer 3 Switch
allows you to un-suppress all routes at once or un-suppress individual routes.
To un-suppress all the suppressed routes, enter the following command at the Privileged EXEC level
of the CLI.
TurboIron#clear ip bgp damping
Syntax: clear ip bgp damping [
The
The
To un-suppress a specific route, enter a command such as the following.
TurboIron#clear ip bgp damping 10.157.22.0 255.255.255.0
This command un-suppresses only the routes for network 10.157.22.0/24.
Removing route dampening from a neighbor routes
suppressed due to aggregation
You can selectively unsuppress more-specific routes that have been suppressed due to
aggregation, and allow the routes to be advertised to a specific neighbor or peer group.
Here is an example.
The aggregate-address command configures an aggregate address. The summary-only parameter
prevents the Layer 3 Switch from advertising more specific routes contained within the aggregate
route. The show ip bgp route command shows that the more specific routes aggregated into
10.1.0.0/16 have been suppressed. In this case, the route to 10.1.44.0/24 has been suppressed.
The following command indicates that the route is not being advertised to the Layer 3 Switch BGP4
neighbors.
TurboIron(config-bgp-router)#aggregate-address 10.1.0.0 255.255.0.0 summary-only
TurboIron(config-bgp-router)#show ip bgp route 10.1.0.0/16 longer
