Which of the following OTV technologies is a logical interface and cannot be a physical interface?
- OTV join interface
- OTV overlay interface
- OTV internal interface
- OTV edge device
An Overlay Transport Virtualization (OTV) overlay interface is a logical interface and cannot be a physical interface. OTV is a means of simplifying the deployment of data center interconnect (DCI), enabling the extension of Layer 2 applications between data centers. An OTV overlay interface is a logical interface that is defined by the user. The OTV overlay interface receives and forwards any Open Systems Interconnection (OSI) networking model Layer 2 frames that must be transmitted to the remote site.
An OTV edge device is typically a virtual device context (VDC) running on A Cisco Nexus switch, such as a Nexus 7000 Series switch. The edge device is responsible for receiving Layer 2 traffic for virtual local area networks (VLANs) that are extended. Ethernet frame traffic is encapsulated into Internet Protocol (IP) packets are transmitted to the remote network.
An OTV join interface is an OTV technology that is a physical or logical Layer 3 interface. An OTV join interface is used to connect an overlay network to remote overlay edge devices. An OTV join interface can be a physical interface, subinterface, or logical interface such as a port channel.
An OTV internal interface is a Layer 2 interface. The OTV internal interface is an interface on the OTV edge device that connects to the VLANs that are being extended. Typically, the OTV internal interface operates similarly to any other Layer 2 switch trunk port or access port and does not require configuration specific to OTV.
