Which configuration must be applied to both Nexus switches to meet these requirements?

An engineer must configure OSPF routing on Cisco Nexus 9000 Series Switches. The IP subnet of the Eth 1/2 interface for both switches must be advertised via OSPF. However, these interfaces must not establish OSPF adjacency or send routing updates. The current OSPF adjacency over the interface Eth1/1 on SW1 and Eth1/1 on SW2 must remain unaffected.

Which configuration must be applied to both Nexus switches to meet these requirements?
A . interface ethernet 1/2
passive-interface default
B . Interface ethernet 1/2
Ip ospf network point-to-point
C . interface ethernet 1/2
ip ospf passive-interface
D . interface ethernet 1/2
no ip ospf passive-Interface

Answer: C

Explanation:

The ip ospf passive-interface command is used to prevent OSPF adjacency and routing updates from being sent or received on a specific interface, while still advertising the interface subnet via OSPF. This command is useful for stub networks or loopback interfaces that do not need to form OSPF neighbor relationships. The other commands either enable OSPF adjacency by default, change the OSPF network type, or disable OSPF passive mode.
