The setting of the Restart-time value is not directly related to the configuration of
Graceful-restart. That is, the Restart-time can be configured before the
configuration of the Graceful-restart ability. The default value of the Restart-time is
180 seconds.

Configuring timer of a peer (group)
The peer timer command is used to configure timers of a BGP peer (group),
including the keep-alive message interval and the hold timer. The preference of
this command is higher than the timer command that is used to configure timers
for the whole BGP peers.
Perform the following configuration in BGP view.
