Embodiment

[0053] see Figure 5 , which is a system block diagram of the virtual private local area network service provider edge device in this example, which includes a service provider edge device body, a control module, a port dynamic setting module and a VPLS service data forwarding module, wherein the control module is used in the user edge device When the service provider edge device is connected and the user edge device selects VPLS service, it is configured to bind the VPLS instance. The VPLS instance includes the peer service provider edge device (PE, Provider Edge) address and its VPN ID, the VPLS instance refers to the Ethernet bridge functional entity, which forwards Layer 2 packets according to the MAC and VLAN tag, and judges whether the access mode of the user edge device is Ethernet, and if not, enters normal processing process, if so, query the port number of the physical port receiving the data of the user edge device, and command the port dynamic setting module to set...

Abstract

The invention relates to a local area network technology, and provides a virtual private local area network service (VPLS) message processing method and equipment. The processing method and the equipment solve the problem that a tag carried in the existing transmission message is abandoned if inconsistent with an affiliated VLAN (Virtual Local Area Network) of a port in a boundary router of a service provider. The processing method adopts the technical scheme that the method comprises the steps that CE (Customer Edge) equipment is connected into PE (Provider Edge) equipment to select a VPLS; the PE equipment configures and binds a VPLS example at a third-layer port of the PE equipment; whether a connection mode is an Ethernet port is judged; if so, the port number of a physical port receiving data of the CE equipment is enquired; the port is set as a QinQ mode; when the PE equipment receives a message, a tag is added at the second-layer head of the message; the value of the tag is a VLAN ID (Identity) corresponding to the port number; and the message is transmitted by a VPLS data forwarding module. The processing method and the equipment have the benefits that an effect of unvarnished data transmission is achieved, and the processing method and the equipment are suitable for a virtual private local area network.

Description

technical field [0001] The invention relates to local area network technology, in particular to virtual private local area network technology. Background technique [0002] Virtual private LAN service VPLS (Virtual Private LAN Service) is a layer-2 virtual private network VPN (Virtual Private Network) technology based on multi-protocol label switching MPLS (Multiple Protocol Label Switch) and Ethernet technology. Geographically dispersed points access the network at the same time and access each other, just as these geographically dispersed users are directly connected to the local area network. [0003] The QinQ (tag in tag) protocol is based on 802.1Q. The main purpose of this protocol is to shield the virtual local area network VLAN (Virtual Local Area Network) used internally by users, thereby reducing the number of VLANs on the service provider network. Its core idea That is, only one public network VLAN number is assigned to each user. When a user packet with a tag en...
