Problems solved by technology

[0007] Therefore, when users of different virtual switching instances access the broadband access server to surf the Internet through the carrier edge device, many virtual switching instances must be created on the carrier edge device, and many sub-interfaces must be created between the carrier edge device and the broadband access server , different sub-interfaces are added to different virtual switching instances, the configuration and management are very complicated

Embodiment Construction

[0034]The core content of the present invention is that, by setting a shared virtual switching instance on the message forwarding device of the virtual private area network (for example, the operator's edge equipment PE), the intercommunication between multiple virtual switching instances and one shared virtual switching instance is realized, reducing the number of virtual switching instances. The configuration and management complexity of accessing the private LAN to the three-layer network; in addition, by starting the arp proxy function and setting the three-layer logical interface on the message forwarding device with the shared virtual switching instance, users of different virtual switching instances can be connected to each other Layer isolation, three-layer access.

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

Abstract

The invention relates to a report transfer method of virtual special local network and relative device. Wherein, said method comprises: setting report transfer device in the virtual special local network, which comprises at least one share virtual exchanger; setting the members of said exchanger, while the member is several virtual exchangers of virtual special local network; when the user of virtual special local network sends request, it will be transferred by the report transfer device. The invention sets the share virtual exchanger, starts the Arp proxy function and builds three layers of logic interface to complete the external network access of different virtual exchangers in virtual special local network, without building many virtual exchangers at the edge device of operator, to simplify the setting and management of virtual special local network. Therefore, user can easily access external network, or be insulated.

Description

technical field [0001] The present invention relates to a virtual private local area network, in particular to a message forwarding method and device of a virtual private local area network that realizes the sharing of multiple virtual switching instances by setting a shared virtual switching instance. Background technique [0002] Virtual Private LAN Service (VPLS, Virtual Private LAN Services) is a Layer 2 virtual private network (VPN, Virtual Private Network) technology, which provides similar LAN ( LAN, Local Area Network) business function, which can enable users to simultaneously access the network from multiple geographically dispersed points and access each other, just like these points are directly connected to the LAN. The role of VPLS is a virtual LAN switch. [0003] Figure 1 is a typical network diagram of VPLS. As shown in the figure, the interface of the CE (Custom Edge) device is added to the VPLS VSI (Virtual Switch Instance, Virtual Switch Instance), and t...
