BGP4+ suppressed routes can be reactivated using a CLI command.

Before you begin

About this task

The show ipv6 bgp dampened-paths command is entered to verify that there are BGP4+ dampened routes. The clear ipv6 bgp dampening command is entered to reactivate all suppressed BGP4+ routes. The show ipv6 bgp dampened-paths command is re-entered to verify that the suppressed BGP4+ routes have been reactivated.

Procedure

  1. Enter the exit command until you return to Privileged EXEC mode.
    device(config)# exit
  2. Enter the show ipv6 bgp dampened-paths command to display all BGP4+ dampened routes.

  3. Enter the clear ipv6 bgp dampening command to reactivate all suppressed BGP4+ routes.
    device# clear ipv6 bgp dampening
    
  4. Enter the show ipv6 bgp dampened-paths command to verify that there are no BGP4+ dampened routes.
    device# show ipv6 bgp dampened-paths
    device#   
    

Example

The following example reactivates all suppressed BGP4+ routes and verifies that there are no suppressed routes.

device(config-bgp-router)# exit
device(config)# exit
device# show ipv6 bgp dampened-paths
device# clear ipv6 bgp dampening
device# show ipv6 bgp dampened-paths
