Disabling OSPFv2 graceful restart

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 globally.
   

   device(config)# router ospf

3. Enter the no graceful restart command to disable GR on the device.
   

   device(config-router-ospf-vrf-default-vrf)# no graceful-restart

The following example disables GR.

device# configure terminal
device(config)# router ospf 
device(config-router-ospf-vrf-default-vrf)# no graceful-restart
