Secure Tunneling Between Two Switches

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

Can Cisco TrustSec Switch-to-Switch Link Security in Manual Mode be the solution?

Encryption of the uplink is the way to go but your 3560v2 switch does NOT support MACSec.

MACSec support starts with 3560X/3750X, 3650/3850.
