However, the TRILL protocol does not define the behavior of links between TRILL devices and non-TRILL devices
[0004] That is to say, if a non-multi-link transparent interconnection device is installed between the multi-link transparent interconnection devices, under the TRILL protocol, although the packet containing the multi-link transparent interconnection header can be transmitted through the non-multi-link transparent interconnection device, it cannot be transmitted. Data is sent to non-Multi-link transparent interconnection devices to access non-multi-link transparent interconnection devices, that is, non-multi-link transparent interconnection devices connected between multi-link transparent interconnection devices cannot be accessed under the TRILL protocol and / or or management

The invention discloses a device for supporting a multi-link transparent interconnection protocol and a communication method thereof. The device for supporting the multi-link transparent interconnection protocol comprises a memory, a processor and a communication interface. The memory comprises a lookup table. The processor is coupled to the memory. The communication interface is coupled to the processor, comprises a trunk port and an access port, and is used for receiving the first packet. When the processor judges that the output port corresponding to the destination address of the first packet is a backbone port and nickname information corresponding to the destination address does not exist according to the lookup table, a second packet is transmitted by the backbone port of the communication interface. The second packet includes an enable region bit and includes the same interest data as the first packet. Under the condition that the non-multi-link transparent interconnection device and the multi-link transparent interconnection device are arranged at the same time, the non-multi-link transparent interconnection device is effectively accessed and / or managed, and the probability that a packet is cyclically forwarded is reduced.
Description
technical field [0001] This case relates to a device supporting the multi-link transparent interconnection protocol and its communication method, and in particular to a device supporting the multi-link transparent interconnection protocol and its communication method connected to a non-multi-link transparent internet network. Background technique [0002] Transparent Interconnection of Lots of Links (TRILL) technology is a standard of the Internet Engineering Task Force (IETF) protocol. Multi-link transparent interconnection technology uses layer 3 routing technology to construct a fairly large layer 2 network cloud, so when the host moves in the cloud of this layer 2 network, it can transfer smoothly without changing the IP address setting Continue to operate and provide services to another node (such as a router). [0003] The TRILL protocol defines the behavior of the access link (Access Link) to deal with the Ethernet frames that are sent out by non-TRILL devices and in...
