Hi,
We have 3 buildings in a campus. We occupy building 1 and 3. Building 2 belongs to someone else. However, building 2 switch connects both building 1 and 3. How do I create a point-to-point secure tunnel between the two 3560v2 layer 2 switches in building 1 and 3 thru the transit switch in building 2 in a layer 2 environment?
QinQ does not meet the requirement because we want to prevent man-in-the-middle access from the transit switch in Building 2.
Thanks!
Kevin
