Abstract
One embodiment of the present invention provides a switch. The switch includes a notification mechanism. The notification mechanism constructs a single message that contains a locally learned MAC address associated with a local device, a TRILL RBridge identifier associated with the switch, and an identifier of an interface associated with the MAC address. In some embodiments, the switch includes a data structure and an entry management mechanism. The data structure stores device information learned at a remote switch, wherein the device information includes a MAC address of a device, a TRILL RBridge identifier associated with the remote switch, an identifier of an interface coupled to the device, and a type indicator of the MAC address. The entry management mechanism manages an entry in the data structure based on the RBridge identifier and the interface identifier.
