3. graceful-restart lifetime
DETAILED STEPS
Configuring the Minimum Time Required Between RestartsThis section describes the task of modifying the minimal time that is required between allowable
graceful restarts. The purpose of this interval is to prevent the waste of system resources if the OSPFv3
process is repeatedly crashing for reasons that must be diagnosed. The default value for the interval is
90 seconds. The range is 90–3600 seconds.

Command or Action Purpose
Step1 config
Example:
RP/0/RP0/CPU0:single10-hfr#config
RP/0/RP0/CPU0:single10-hfr(config)
Enters global configuration mode.
Step2 router ospfv3 <process-name>
Example:
RP/0/RP0/CPU0:single10-hfr(config)# router
ospfv3 test
Enters router configuration mode for OSPFv3. The process
name is a WORD that uniquely identifies an OSPF routing
process. The process name is any alphanumeric string no
longer than 40 characters without spaces.
Step3 graceful-restart lifetime
Example:
RP/0/RP0/CPU0:single10-hfr(config-ospfv3)#grace
ful-restart lifetime 120
Specifies a maximum duration for a graceful restart.
