When using Overlay Transport Virtualization (OTV), how do L2 multicast frames traverse the
overlay?

A.
The L2 multicast frames are encapsulated in an OTV packet using the configured control-group
multicast address for transport

B.
The L2 multicast frames are dropped because multicast cannot be carried across the overlay

C.
The L2 multicast frames are encapsulated in an OTV packet using the configured data-group
multicast address for transport

D.
The L2 multicast frames are forwarded natively across the overlay based on their multicast IDs
