Abstract
A system for facilitating segmentation by a first switch of an overlay tunnel fabric is provided. During operation, the system can receive a route update packet for the fabric. The packet can be based on a control plane that allows the exchange of route information via the tunnel and can include a first media access control (MAC) address learned at a second switch and a first role identifier of a first role. The first role can indicate a level of access granted to a first device associated with the first MAC address. The system can store the first MAC address and the first role identifier in a local address data structure. Upon receiving a packet from the first device, the system can then determine, based on the first role identifier and a first segmentation policy, whether a local device is allowed to receive the packet from the first device.
