• Specify the operating mode and type of events that trigger a graceful restart.
CONF-IPV6-ROUTER-OSPF mode
graceful-restart mode [planned-only | unplanned-only]
– Planned-only: the OSPFv3 router supports graceful restart only for planned restarts. A planned restart is when you
manually enter a redundancy force-failover rpm command to force the primary RPM over to the secondary RPM.
During a planned restart, OSPFv3 sends out a Grace LSA before the system switches over to the secondary RPM. OSPFv3
is notified that a planned restart is happening.
– Unplanned-only: the OSPFv3 router supports graceful-restart only for unplanned restarts. During an unplanned restart,
OSPFv3 sends out a Grace LSA once the secondary RPM comes online.
The default is both planned and unplanned restarts trigger an OSPFv3 graceful restart. Selecting one or the other mode restricts
OSPFv3 to the single selected mode.
• Disable OSPFv3 graceful-restart.
CONF-IPV6-ROUTER-OSPF mode
no graceful-restart grace-period
