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

A device supporting a multi-link transparent interconnection protocol and a communication method thereof. The device supporting the multi-link transparent interconnection protocol includes a memory, a processor and a communication interface. The memory contains look-up tables. The processor is coupled to the memory. The communication interface is coupled to the processor and includes a trunk port and an access port for receiving the first packet. When the processor determines that the output port corresponding to the destination address of the first packet is a trunk port according to the lookup table and there is no nickname information corresponding to the destination address, the trunk port of the communication interface transmits the second packet. The second packet contains the enable field bits and contains the same payload data as the first packet. The present invention effectively accesses and / or manages the non-multi-link transparent interconnection device and reduces the probability of packets being cyclically forwarded under the condition that the non-multi-link transparent interconnection device and the multi-link transparent interconnection device are installed at the same time.
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...
