Configures the restart time used with graceful BGP restart. This is the maximum time a receiver router waits for a restarting router to come back up.
| seconds | Specifies the restart time. The range is 1 to 3600 seconds. |
The default is 120 seconds.
Before you can enter this command, you must disable BGP services on the switch with the disable bgp command.
This command configures the restart timer. This timer is started on the receiver router when it detects the neighbor router is restarting (usually when the peer TCP session is reset). At that time, routes from the restarting router are marked as stale, but are preserved in the routing table. The timer is stopped when the restarting BGP neighbor goes to the ESTABLISHED state (it has finished restarting). If the timer expires, the stale routes are deleted.
The following command configures the graceful BGP restart timer:
configure bgp restart restart-time 200
