Configure Graceful Restart (RFC 3623) restarting support.
When enabled, the default grace period is 120 seconds.
To perform a graceful shutdown, the "graceful-restart prepare ip ospf"
EXEC-level command needs to be issued before restarting the ospfd daemon.

restarts. By default, it supports both planned and

.. clicmd:: graceful-restart prepare ip ospf
Initiate a graceful restart for all OSPF instances configured with the
"graceful-restart" command. The ospfd daemon should be restarted during
the instance-specific grace period, otherwise the graceful restart will fail.
This is an EXEC-level command.
