TRILL (Transparent Interconnection of Lots of Links) network-based remote mirror image implementation method and equipment

Abstract

The invention discloses a TRILL (Transparent Interconnection of Lots of Links) network-based remote mirror image implementation method and equipment. The method comprises the following steps of: when RB (Router Bridge) equipment determines that a received message is required to be mirrored, the RB equipment mirrors the message to an external loopback port of the equipment; the RB equipment increases a mirror image VLAN (Virtual Local Area Network) Tag of the outer layer in the mirror image message aiming at the mirror image message looped back on the loopback interface; TRILL package is performed on the mirror image message to obtain a TRILL message according to a TRILL distribution tree corresponding to the mirror image VLAN; and the RB equipment transmits the TRILL message to a remote mirror image destination port through the TRILL distribution tree corresponding to the mirror image VLAN, so that an original mirror image message is acquired by the remote mirror image destination port after the TRILL package and the mirror image VLAN Tag in the TRILL message are stripped. According to the method and the equipment, monitoring 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 the data center network, the STP (Spanning Tree Protocol, Spanning Tree Protocol) protocol used in ordinary Ethernet cannot meet the needs of the data center network. ) passed and formulated the 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 second layer In the network, the necessary transformation and improvement have been carried out, so that the data center network can quickly converge, and bandwidth resources can be used reasonably and effectively. [0003] In a TRILL network, devices are connected to each other through Trill ports. There are three types of Trill ...

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.
