Run the command set protocols ospf area to define an OSPF area and disallow injecting inter-area routes. Optional parameter instance-id can be included to specify the OSPFv2 multi-instance ID. Optional parameter vrf can be used to specify a VRF, if no VRF is specified the command takes effect on the default VRF. The keyword no-summary is used to disable injecting inter-area summaries into the specified stub area. The no-summary option makes the area totally stubby.
Multi-Instance OSPF is 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 area can be used to remove this configuration.
