Information
The running router sets remaining time value to the current adjacency hold time. This can be
overridden by implementing this command.
Override the default restart-wait time by entering the no graceful-restart restart-wait command.
When restart-wait is disabled, the current adjacency hold time is used.
Be sure to 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 accordingly only
when you have configured graceful-restart t3 adjacency.
