◦ Transport agnostic: OTV is IP encapsulated and can therefore use any core capable of forwarding IP traffic. OTV therefore does not pose any requirements on the core transport.
◦ Transparent to the sites: OTV extensions do not affect the design or protocols of the Layer 2 sites that OTV interconnects. It is as transparent as a router connection to the Layer 2 domain and therefore does not affect the local spanning tree or topology.
