A planned restart occurs when you enter the redundancy force-failover rpm command to force
the primary RPM to switch to the backup RPM. During a planned restart, OSPF sends out a
Type-11 Grace LSA before the system switches over to the backup RPM.
An unplanned restart occurs when an unplanned event causes the active RPM to switch to the
backup RPM, such as when an active process crashes, the active RPM is removed, or a power
failure happens. During an unplanned restart, OSPF sends out a Grace LSA when the backup RPM
comes online.
