Disabling OSPFv3 graceful restart helper

The OSPFv3 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 ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 globally.
   

   device(config)# ipv6 router ospf

3. Enter the no graceful-restart helper command to disable the GR helper.
   

   device(config-ipv6-router-ospf-vrf-default-vrf)# no graceful-restart helper

Example

The following example disables the GR helper.

device# configure terminal
device(config)# ipv6 router ospf 
device(config-ipv6-router-ospf-vrf-default-vrf)# no graceful-restart helper
