A. B. C. D.D
To include an interface route into OSPF as an internal OSPF route while prohibiting adjacency formation for that interface, you should include the interface under the [edit protocols ospf area area-number] hierarchy level along with the passive configuration option.
The configuration parameter that allows a Junos device to include an interface route into OSPF while prohibiting adjacencies from forming is "passive."
The "passive" parameter is used in OSPF configuration to indicate that the OSPF interface is not to participate in the OSPF routing protocol as an active router. This means that the interface will still advertise its connected network as an OSPF route, but it will not form any OSPF adjacencies or participate in the calculation of the OSPF topology.
This parameter is useful in scenarios where the network administrator wants to include the interface route into the OSPF network but does not want the interface to actively participate in the OSPF protocol. This could be due to security concerns or because the interface is not capable of running OSPF protocol.
The other options listed in the question are:
A. "inactive" is a configuration command that disables a configuration statement. This command is not used in OSPF configuration.
B. "no-peer-advertise" is a parameter used in BGP configuration that prevents the router from advertising the existence of a BGP peer to other BGP peers. This command is not used in OSPF configuration.
C. "disable" is a configuration command used to disable an interface or a protocol. This command is not used in OSPF configuration.
Therefore, the correct answer is D. "passive".
