Problems solved by technology

[0007] Remote mirroring packets are broadcast from the source port to the destination port through the remote mirroring VLAN in the intermediate network, causing flooding of remote mirroring packets in the network, and sometimes even seriously affecting the normal traffic transmission of the intermediate network; in addition, remote mirroring packets The text is transmitted in the network by broadcasting, which has security risks

Embodiment Construction

[0057] Aiming at the above-mentioned problems in the prior art, the embodiment of the present invention provides a technical solution for mirrored packet transmission in a TRILL network. In this technical solution, by establishing the corresponding relationship between the source mirroring group and the destination mirroring group, the forwarding path of the mirrored message is determined by using the unicast distribution tree or the multicast distribution tree in the TRILL network, which avoids the mirrored message being transmitted in the intermediate network. Broadcast flooding saves bandwidth resources for mirrored message transmission and improves the security of mirrored message transmission.

[0058] Wherein, in the embodiment of the present invention, the corresponding relationship between the source mirroring group and the destination mirroring group may specifically be the corresponding relationship between the remote VLAN of the source mirroring group and the Nicknam...

Abstract

The invention discloses a method and equipment for mirroring message transmission in a TRILL network. The method includes: when the RB device where the mirroring source port is located receives a message from the mirroring source port, Determine the remote mirroring VLAN of the corresponding source mirroring group; the RB device where the mirroring source port is located determines the Nickname of the RB device where the mirroring destination port corresponding to the remote mirroring VLAN of the source mirroring group is located; the RB device where the mirroring source port is located sends the message Copy, add the remote mirroring VLAN of the source mirroring group, encapsulate it into a TRILL message, send it to the RB device where the mirroring destination port is located through the TRILL distribution tree, and forward it to the corresponding data monitoring device by the RB device where the mirroring destination port is located. In the present invention, the bandwidth resource of the transmission of the mirrored message is saved, and the security of the transmission of the mirrored message is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for transmitting mirrored messages in a TRILL network. Background technique [0002] The TRILL (Transparent Interconnection of Lots of Link) protocol introduces the design idea of ​​the layer-3 routing technology IS-IS (Intermediate System-to-Intermediate System, intermediate system to intermediate system) into the layer-2 network, and Necessary modifications were made. In this way, the simplicity and flexibility of the second layer are organically integrated with the stability, scalability and high-tech performance of the third layer. [0003] When the source device is not directly connected to the data monitoring device, the device directly connected to the data monitoring device is used as the destination device. The source device needs to copy the mirrored message to the destination device, and then the destination device forwards the mirrored message to the ...
