Disabling OSPFv2 graceful restart helper

The OSPFv2 graceful restart (GR) helper is enabled by default, and can be disabled on a routing device.
  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enter the router ospf command to enter OSPF router configuration mode and enable OSPFv2 on the device. 
    device(config)# router ospf
  3. Enter the graceful-restart command using the helper-disable keyword to disable the GR helper. 
    device(config-ospf-router)# graceful-restart helper-disable

The following example disables the GR helper. 

device# configure terminal
device(config)# router ospf 
device(config-ospf-router)# graceful-restart helper-disable
