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.

To establish adjacency to the remote peer by using multicast, the engineer needs to configure the otv data-group command with a multicast address range that is unique for each site. This command specifies the multicast group that is used to send and receive OTV data traffic. To enable OTV advertisements for VLAN 100 to the other site, the engineer needs to configure the otv extend-vlan command with the VLAN number. This command specifies which VLANs are extended across the overlay network.

Private Cloud: owned, managed, and operated by a single organization. Community Cloud: Owned, managed, and operated by one or more organizations or teams. Public Cloud: Provisioned for open use. Hybrid Cloud: At least two or more separate cloud infrastructures are connected together to facilitate hosted data and application portability.

The system will automatically revert to the backup image version if the endpoint fails to boot from the new firmware image. This is a feature of the Fabric Interconnects that ensures high availability and reliability. The GOLD firmware image is used for diagnostics and troubleshooting, not for normal operation. The kickstart image is used for booting the Nexus switches, not the Fabric Interconnects.

The vsan bind interface command is used to statically assign VSAN membership to a virtual Fibre Channel interface. This command overrides the VSAN membership that is derived from the physical interface or the default VSAN. The other commands are either invalid or do not apply to virtual Fibre Channel interfaces.
