Command Reference OSPFv2 Commands
value of the graceperiod varies from 1s to 1800s. The default value is
120s.
inconsistent-lsa-checking
Enables topological change detection. If any topological change is
detected, OSPF exits the GR process to complete convergence.After
GR is enabled, topological change detection is enabled by default.
This function is enabled by default.
Routing process configuration mode
GR is configured based on the OSPF instance. Different instances could be configured with different
parameters according to the actual situation.
The graceful restart interval is the longest time between the OSPF restart and the graceful restart. In
this period, you can perform link status reconstruction to restore the OSPF status to the original. With
the interval times out, the OSPF will exit GR and perform common OSPF operations.
The GR interval is 120 seconds set with the graceful-restart command, and the graceful-restart
grace-period command allows you to change the interval explicitly.
GR is unavailable when the Fast Hello function is enabled.
The following example enables GR for the OSPF instance 1 and sets the restart interval for GR.
Ruijie(config)# router ospf 1
Ruijie(config-router)# graceful-restart
Ruijie(config-router)# graceful-restart grace-period 60
Enables the OSPF graceful-restart helper.
2.22 graceful-restart helper
Use this command to enable the graceful restart helper function. Use the no form of this command to
restore the default setting.
