Usage Information
OSPFv3 graceful restart supports planned-only and/or unplanned-only restarts. The
default is support for both planned and unplanned restarts.
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.
By default, both planned and unplanned restarts trigger an OSPFv3 graceful restart.
Selecting one or the other mode restricts OSPFv3 to the single selected mode.
