set protocols ospf graceful-restart helper enable

Run the command set protocols ospf graceful-restart helper enable to enable the OSPF Graceful Restart (GR) Helper capability. By default, helper support is disabled for all neighbors. This config enables/disables helper support on this router for all neighbors. To enable/disable helper support for a specific neighbor, the router-id (A.B.C.D) has to be specified.

Optional parameter vrf can be used to specify a VRF, if no VRF is specified the command takes effect on the default VRF.

Optional parameter instance-id can be included to specify the OSPFv2 multi-instance ID in the default VRF. By default, OSPF GR Helper capability is disabled.

If helper is enabled for specific neighbors, the global helper configuration for other neighbors will not take effect.
Multiple instances of OSPF are only allowed in the default VRF. A maximum of 8 instance can be configured in the default VRF. In non-default VRFs, only single instance OSPF can be configured.

The command delete protocols ospf graceful-restart helper enable can be used to remove this configuration.
