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.

Commands

the full MTU provides early error detection of large frame transmission problems or mismatched MTUs on
adjacent interfaces.
