only" role. In a "restarting-only" role, OSPFv3 does not participate in the graceful restart of a neighbor. graceful-restart mode Specify the type of events that trigger an OSPFv3 graceful restart. E-Series TeraScale, Z-Series, S4810 Syntax graceful-restart mode {planned-only | unplanned-only} To disable graceful restart mode, enter no graceful-restart mode. Parameters planned-only unplanned-only (OPTIONAL) Enter the keywords planned-only to indicate graceful restart is supported in a planned restart condition only. (OPTIONAL) Enter the keywords unplanned-only to indicate graceful restart is supported in an unplanned restart condition only. Defaults Command Modes Command History OSPFv3 graceful restart supports both planned and unplanned failures. ROUTER OSPFv3 Version 9.1.(0.0) Version 8.4.2.2 Introduced on the S4810 and Z9000. Introduced on the E-Series TeraScale. 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. ipv6 ospf area Enable IPv6 OSPF on an interface. C-Series, E-Series, Z-Series, S4810 Syntax ipv6 ospf process id areaarea id To disable OSPFv6 routing for an interface, use the no ipv6 ospf process-id area area-id command. Parameters process-id Enter the process identification number. 1111
