Run the command set protocols ospf graceful-restart enable to enable the OSPF Graceful Restart (GR) capability on the restarting device. 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 capability is disabled.
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 enable can be used to remove this configuration.
Command Syntax
set protocols ospf [instance-id <instance-id>] [vrf<vrf-name>] graceful-restart enable <true | false>
delete protocols ospf [instance-id <instance-id>] [vrf <vrf-name>] graceful-restart enable
