Explanation:
OTV(Overlay Transport Virtualization) is a technology that provide layer2 extension capabilities between different data centers. In its most simplest form OTV is a
new DCI (Data Center Interconnect) technology that routes MAC-based information by encapsulating traffic in normal IP packets for transit.
Overlay Transport Virtualization (OTV) on the Nexus 7000 is an industry-first technology that significantly simplifies extending Layer 2 applications across distributed
data centers. You can now deploy Data Center Interconnect (DCI) between sites without changing or reconfiguring your existing network design.
