Abstract:
In one embodiment, a method includes obtaining an indication that a device is attached to a provider edge. The device has a media access control (MAC) address, wherein the device was previously attached to a first provider edge (PE) of a Multiprotocol Label Switching (MPLS) network. The method also includes issuing a first advertisement that identifies the MAC address. The first advertisement includes a first MAC address mobility attribute arranged to indicate a number of times the MAC address has moved with respect to the MPLS network.
