Problems solved by technology

[0003] The current Trill network provides full interconnection of the user-side network. After different user-side networks are connected to the Trill network, they can always reach any other remote virtual local area network (VirtualLocalAreaNetwork, VLAN) through the Trill network. Whether the network belongs to the same enterprise user, and no matter whether these scattered VLAN networks need to be interconnected or prohibited, the security is poor

Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.

[0024] see figure 1 , which is a schematic diagram of an application scenario for implementing packet forwarding by applying the embodiment of the present invention:

[0025] figure 1 Among them, the routing bridge (RoutingBridge, RBridge) device is responsible for forwarding the message sent by the first terminal, and the RB1-RB4 devices all have user-side VLAN network access. In the prior art, a Trill connection is established between any two RBridge devices, that is, terminals in all VLANs can be interconnected, and the se...

Abstract

The invention provides a message forwarding method and a message forwarding device. The message forwarding method comprises the steps of receiving a first message sent by a first terminal located in a first virtual local area network; determining a first instance identifier of a first instance corresponding to the first virtual local area network; querying a destination MAC address of a destination terminal of the first message according to the first instance identifier in a pre-established media access control MAC address list corresponding to instance identifiers; and forwarding a first packaged message to a destination routing bridge according to the destination MAC address, enabling the first message acquired through unpacking the first packaged message by the destination routing bridge to be sent to the destination terminal of the first message, wherein the first packaged message is a message acquired by carrying out Trill head packaging on the first message. The method and the device provided by the invention can realize isolation for a user side virtual local area network in a Trill network, and the network security is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] Multi-link transparent interconnection (TRansparent Interconnection of Lots of Links, Trill) protocol introduces the design idea of ​​Layer 3 routing technology Intermediate System-to-Intermediate System (Intermediate System-to-Intermediate System, IS-IS) into the Layer 2 network, thus making the Layer 2 simple and flexible Combined with the stability, scalability and high performance of the third layer, it is very suitable for the data center to build a large-scale two-layer network. [0003] The current Trill network provides full interconnection of the user-side network. After different user-side networks are connected to the Trill network, they can always reach any other remote virtual local area network (VirtualLocalAreaNetwork, VLAN) through the Trill network. Whether the network belongs to...
