Embodiment Construction

[0030] Since the establishment of pseudowires based on multipoint services cannot be easily and simply implemented in the prior art, and the inventors of the present invention have found that the border gateway protocol (BGP) has not been used so far, and the implementation of basic multipoint services is realized with less improvement The solution is fully compatible with the deployed PE equipment that uses BGP to implement VPLS. Based on this, the embodiment of the present invention provides a method for implementing Ethernet-based multipoint services. On the basis of RFC4761, a solution for implementing VPLS based on BGP to implement E-TREE .

[0031] The method for realizing the Ethernet-based multipoint service provided by the embodiment of the present invention, its process is as follows figure 2 As shown, the execution steps are as follows:

[0032] Step S101: The first operator edge device PE configures attributes for the connected node.

[0033] Among them, the fir...

Abstract

The invention discloses an Ethernet-tree realization method, an Ethernet-tree realization system, an Ethernet-tree realization device and network equipment. The method comprises the following steps of: judging whether a first node is a leaf node or a root node by using a first provider edge (PE); allocating an identifier (ID) in a leaf node ID interval to the leaf node, and configuring customer edge ID block offset and a customer edge ID block size according to the ID range and initial ID of a root node ID interval; allocating the ID in the root node ID interval to the root node, configuring the customer edge ID block offset and the customer edge ID block size according to the ID ranges and initial IDs of the leaf node ID interval and the root ID interval; and generating network layer reach information according to the allocated ID, the customer ID block offset and the customer edge ID block size, and transmitting the network layer reach information to a second PE. The leaf nodes are isolated by the setting of the node IDs so as to avoid the establishment of a pseudo wire between the leaf nodes and simply and conveniently realize an Ethernet-tree.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a border gateway protocol (Border Gateway Protocol, BGP)-based Ethernet-based multipoint service implementation method, system, device and network equipment. Background technique [0002] Metro Ethernet Forum (MEF) 10.1 and MEF6.1 define three Ethernet services: point-to-point Ethernet line (E-line, Ethernet line), multipoint-to-multipoint Ethernet local area network (E-LAN, Ethernet LAN) And point-to-multipoint basic multipoint service (E-tree, Ethernet Tree). E-TREE is a hybrid technology of E-LAN ​​and E-LINE: in an E-TREE instance, there may be either a multipoint-to-multipoint (E-LAN) connection or a point-to-point (E-LINE) connection. From this point of view, E-LAN ​​is a special E-TREE, all of its nodes are root nodes, and there is no communication limitation. [0003] E-TREE technology can provide users with Internet access, Internet Protocol Telev...
