Usage guidelines
The T3 timer specifies the GR interval. The GR interval is set as the holdtime in hello PDUs. Within the
interval, the neighbors maintain their adjacency with the GR Restarter. If the GR process has not
completed within the holdtime, the neighbors tear down the neighbor relationship and the GR process
fails.
Examples
# Configure the T3 timer of IS-IS process 1 as 500 seconds.
