GracefulRestartTimer
BGP Graceful Restart timers configuration
{
"restart_timer": 0,
"stale_timer": 0
}
Maximum time BGP speaker will take for the BGP session to be re-established after a restart. Ranges from 1 sec to 3600 sec. This can be used to speed up routing convergence by its peer in case that the BGP speaker does not come back after a restart. If the session does not get re-established within the "Restart Time" that the Restarting Speaker advertised previously, the Receiving Speaker will delete all the stale routes from that peer.
Maximum time before stale routes are removed from the RIB when the local BGP process restarts. Ranges from 1 sec to 3600 sec.
