Run the command set protocols ospf router-id to configure OSPF router ID. The router ID should be unique within the OSPF domain and is in the IPv4 dotted decimal format. Optional parameter instance-id can be included to specify the OSPFv2 multi-instance ID. The optional parameter vrf can be used to specify OSFPv2 instance for a particular VRF. If VRF is not defined then OSPFv2 instance takes effect for the default VRF.

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.

Run the command delete protocols ospf route-id to delete this configuration.
