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 support is enabled for a specific neighbor, the 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.
