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.

Scalable MAC address distribution in an Ethernet fabric switch

One embodiment of the present invention provides a switch. The switch includes a storage and a lookup mechanism. The storage stores a first table that contains an entry corresponding to a media access control (MAC) address of a device and an identifier of a remote switch associated with the device. The storage also stores a second table that contains an entry indicating a local outgoing interface corresponding to the remote switch. The lookup mechanism identifies the local outgoing interface corresponding to the device based on the first table and the second table.

Efficient TRILL forwarding

Efficient trill forwarding

One embodiment of the present invention provides a switch. The switch includes an ownership management mechanism and a notification mechanism. The ownership management mechanism maintains a local ownership association between the switch, and a medium access control (MAC) address learned at the switch and terminates the local ownership association for the MAC address. The notification mechanism generates a first notification indicating the local ownership association and a second notification indicating the termination of the local ownership association.
