Usage OSPFv3 graceful restart supports planned-only and/or unplanned-only restarts. The default is support Information 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. ipv6 ospf area c e Enable IPv6 OSPF on an interface. Syntax ipv6 ospf process-id area area-id To disable OSPFv6 routing for an interface, use the no ipv6 ospf process-id area area-id command. Parameters process-id area area-id Enter the process identification number. Specify the OSPF area.
