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
Number of external LSA 0. Checksum Sum 00000000
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
