show ip bgp dampened-paths
Displays BGP routes that are currently dampened.
Syntax: show ip bgp dampened-paths
Description: When route dampening is enabled, an unstable route accumulates penalties each time the route fails. If the accumulated penalties exceed a threshold, the route is no longer advertised. See bgp dampening.
Use the show ip bgp dampened-paths command to display routes that are currently dampened.
Factory Default: None.
Command Mode: Executive and privileged.
Example: The following is sample output from the show ip bgp dampened-paths command:
router#show ip bgp dampened-paths

The following table describes the fields in the display:
Table 4-5. Fields Displayed by show ip bgp dampened-paths Field Description Status codes
Status of the entry in the table. Valid values are:
- * - Entry is valid.
- d - Route is currently damped.
- h - Route has earned some penalty points, but not enough points to exceed threshold. See bgp dampening.
- s - Route is suppressed. See bgp dampening.
- a - Entry is an aggregate route. See aggregate-address.
- i- Entry was learned from an IGP (IS-IS or OSPF) in the local autonomous system.
Network
Internet address of a network.
Next Hop
IP address of the next system used when forwarding packets to the destination network. 0.0.0.0 in this field indicates the router has non-BGP routes to the network.
Reuse
- When the route is damped: Amount of time until the reuse-timer expires.
- When the route has accumulated penalty points, but has not been withdrawn: Amount of time until the accumulated penalties equal 0 and the history flag is removed for this route.
Origin codes
Identifies the origin of the entry. Valid values are listed below.
- i - Entry originated in IGP. Entry was advertised by the network route configuration command.
- e - Entry originated in EGP.
- ? - Entry origin is not clear. Reachability information learned from some other source (usually indicates route is redistributed from IGP into BGP).
- > - Entry identifies the best route for that network.
