The following is a list of the Dell Networking OS version history for this command. Version 9.9(0.0) 9.2(1.0) 9.1.(0.0) 8.4.2.2 8.3.19.0 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S4810 and Z9000. Introduced on the E-Series TeraScale. Introduced on the S4820T. 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 neighbor Configure a static entry in the IPv6 neighbor discovery.
