What happens to L2 Protocols when a tunnel is not terminated?


Howdy, I have a quick questioning that I can not seem to find an answer to.


If I have a UNI port that is configured for dot1q tunneling, and the other side of the circuit is not, what happens to the layer 2 protocol packets? If L2P packets get encapsulated when do they get de-encapsulated if the tunneling command is not on the remote end? Do they just get dropped?
