A remote mirroring method and device based on trill network

Abstract

The invention discloses a method and equipment for realizing remote mirroring based on a TRILL network. The method includes: when the RB device determines that the received message needs to be mirrored, the RB device mirrors the message to the external loopback port of the device; For the mirrored packet looped back on the external loopback port, the RB device adds the outer mirrored VLAN to the mirrored packet? Tag, and according to the TRILL distribution tree corresponding to the mirrored VLAN, TRILL encapsulates the mirrored message to obtain a TRILL message; the RB device sends the TRILL message to the remote mirroring destination port through the TRILL distribution tree corresponding to the mirrored VLAN, so that Does the remote mirroring destination port strip the TRILL encapsulation and mirroring VLAN in the TRILL packet? After the Tag, the original mirrored packet is obtained. In the present invention, the supervision of traffic in the TRILL network is realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for realizing remote mirroring based on TRILL network. Background technique [0002] With the development of data center networks, the STP (Spanning Tree Protocol) protocol used in ordinary Ethernet cannot meet the needs of data center networks. In this context, the IETF (Internet Engineering Task Force, Internet Engineering Task Force) passed and formulated TRILL (Transparent Interconnection of Lots of Links) protocol, which introduces the design idea of ​​the three-layer routing technology ISIS (Intermediate system to intermediate system, intermediate system to intermediate system) into the two-layer network, and carries out necessary transformation and improvement. The data center network can be quickly converged, and bandwidth resources can be used reasonably and effectively. [0003] In a TRILL network, devices are connected to each other through Trill ports...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, the remote mirroring implemented on the switch is realized based on the VLAN broadcast domain, but the common remote mirroring configuration cannot be implemented in the TRILL network: for ordinary traffic entering the TRILL network, the ordinary broadcast after the loopback cannot be realized, and the After the TRILL-encapsulated data flows through the loopback interface in the TRILL network, it will be discarded due to the check of the forwarding adjacency table.
