Network device supporting trill protocol and communication method thereof

Abstract

A network device supporting TRILL protocol includes a memory, a processor, and a communication interface. The memory includes a lookup table stored therein. The processor is coupled to the memory. The communication interface is coupled to the processor. The communication interface includes a trunk port and an access port and is configured to receive a first packet. When the processor determines that an output port corresponding to a destination address of the first packet is the trunk port, and determines that there is a lack of nickname information corresponding to the destination address according to the look up table, a second packet is transmitted through the trunk port of the communication interface. The second packet includes an enable local bit. The second packet and the first packet include the same payload information.

Dependencies are inferred from the claim text.
