Displaying Information About Graceful Restart
This section describes the tasks you can use to display information about a graceful restart.
• To see if the feature is enabled and when the last graceful restart ran, use the show ospf command. 
To see details for an OSPFv3 instance, use the show ospfv3 process-name [area-id] database grace 
command.
Displaying the State of the Graceful Restart Feature
The following screen output shows the state of the graceful restart capability on the local router:
RP/0/RP0/CPU0:router# show ospfv3 1 database grace
 Routing Process “ospfv3 1” with ID 2.2.2.2
 Initial SPF schedule delay 5000 msecs
 Minimum hold time between two consecutive SPFs 10000 msecs
 Maximum wait time between two consecutive SPFs 10000 msecs
 Initial LSA throttle delay 0 msecs
 Minimum hold time for LSA throttle 5000 msecs
 Maximum wait time for LSA throttle 5000 msecs
 Minimum LSA arrival 1000 msecs
 LSA group pacing timer 240 secs
 Interface flood pacing timer 33 msecs
 Retransmission pacing timer 66 msecs
 Maximum number of configured interfaces 255

Step 7
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-ospfv3)# end
or
RP/0/RP0/CPU0:router(config-ospfv3)# commit
Saves configuration changes.
• When you issue the end command, the system prompts 
you to commit changes:
Uncommitted changes found, commit them before 
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the 
running configuration file, exits the configuration 
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and 
returns the router to EXEC mode without 
committing the configuration changes.
–
Entering cancel leaves the router in the current 
configuration session without exiting or 
committing the configuration changes.
• Use the commit command to save the configuration 
changes to the running configuration file and remain 
within the configuration session.
Step 8

process-name
 [
area-id
]] database 
grace
Example:
RP/0/RP0/CPU0:router# show ospfv3 1 database 
grace
Displays the state of the graceful restart link.
