UMN:CLI User ManualV5812G394Therefore, 2 options of the time can be used to speed up routing convergence by its peerin case that BGP doesn‘t come back after a restart.• Restart TimeIt‘s the waiting time for the restarting of Neighboring router‘s BGP process. Restarttime allows BGP process time to restart and implement the internal connection (Thesession). However, if it‘s not working properly, it is considered as the router stops op-erating.• Stalepath TimeAfter BGP process of Neighboring router is restarted, it holds the time until BGP updates the path information. In case that the information of BGP routes is not updateduntil the stalepath time, the switch discards this BGP routes information.To set restart time or stalepath time on Graceful Restarting algorithm, use the followingcommand.Command Mode Descriptionbgp graceful-restart restart-time<1-3600>RouterSets the restart time of Graceful Restart configurationin the unit of second.1-3600: restart time (default: 120)bgp graceful-restart stalepath-time <1-3600>Sets the stalepath-time of Graceful Restartconfiguration in the unit of second.1-3600: stalepath time (default: 30)If you don‘t use Graceful Restart feature or want to return the default value for restart timeor stalepath time, use the following command.Command Mode Descriptionno bgp graceful-restart restart-time [<1-3600>] RouterRestores the default value for restart time.no bgp graceful-restartstalepath-time [<1-3600>] Restores the default value for stalepath time.10.1.3 Administrative Distance for BGPAn administrative distance is a rating of the trustworthiness of a routing informationsource, such as an individual router or a group of routers. Numerically, an administrativedistance is an integer between 1 and 255. In general, the higher the value is, the lowerthe trust rating is. An administrative distance of 255 means the routing information sourcecannot be trusted at all and should be ignored.To configure the administrative distance for BGP, use the following command.Command Mode Descriptiondistance <1-255> A.B.C.D/MRouterConfigures the administrative distance for BGP routes.1-255: the administrative distanceA.B.C.D/M: IP source prefixWORD: name of the access listdistance <1-255> A.B.C.D/MWORD
