Usage
Information
The running router sets the remaining time value to the current adjacency hold time. You can override this
setting by implementing this command.
Override the default restart-wait time by entering the no graceful-restart restart-wait
command. When you disable restart-wait, the current adjacency hold time is used.
Set the t3 timer to adjacency on the restarting router when implementing this command. The
restarting router gets the remaining time value from its peer and adjusts its T3 value so only when you
have configured graceful-restart t3 adjacency.
