DETAILED STEPS
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 ospf process-name 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/0/0/CPU0:LA#show ospfv3 test database grace
Routing Process “ospfv3 test” 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
Number of areas in this router is 1. 1 normal 0 stub 0 nssa
Graceful Restart enabled, last GR 11:12:26 ago (took 6 secs)
Area BACKBONE(0)
Number of interfaces in this area is 1
SPF algorithm executed 1 times
Number of LSA 6. Checksum Sum 0x0268a7
Number of DCbitless LSA 0
Number of indication LSA 0
Number of DoNotAge LSA 0
Flood list length 0
RP/0/0/CPU0:LA#
Command or Action Purpose
Step 1
config
Example:
RP/0/RP0/CPU0:single10-hfr#config
RP/0/RP0/CPU0:single10-hfr(config)
Enters global configuration mode.
Step 2
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.
Step 3
graceful-restart helper
Example:
RP/0/RP0/CPU0:single10-hfr(config-ospfv3)#grace
ful-restart helper disable
Disables the helper capability.
