A communication method and communication system

Abstract

The invention discloses a communication method and a communication system, and relates to the field of data communication. The invention realizes the simultaneous communication between at least two branch user equipment and the central end user equipment by simultaneously enabling the bridging function on the logic interface enabled with the L2TPv3 function. Segment communication. The method includes: the central network device configures a corresponding logical interface for each branch user equipment, and enables the L2TPv3 function on the logical interface, so as to respectively establish a corresponding L2TPv3 interface with each branch network device that enables the L2TPv3 function. Tunnel; the central-end network device adds the interface connected to the central-end user equipment and all configured logical interfaces to the same bridging group; the branch user equipment connected to the branch network device and the central-end user equipment through corresponding L2TPv3 tunnel for communication.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a communication method and a communication system. Background technique [0002] With the rapid development of the Internet, the general types of data services are also more abundant. In an enterprise network, a virtual private network (Virtual Private Network, VPN for short) technology is widely used for data communication. VPN is a remote access technology, which needs to establish a private network on the public network to provide services for each branch user device of the enterprise to access the center end user device. At present, most enterprises widely use Layer 2 Tunneling Protocol Version 3 (Layer 2 Tunneling Protocol Version 3, L2TPv3 for short) to implement VPN. However, in the existing technical solutions for remote access using L2TPv3, it is impossible to use the same IP address on the central end user equipment of the enterprise to communicate with m...

Problems solved by technology

[0004] The present invention provides a communication method and a communication system, which are used to solve the problem that when multiple branch user equipments need to communicate with the center-end user equipment of the enterprise, they must rely on the establishment of communication between the center-end user equipment and the center-end network equipment. The same number of physical links and different IP addresses are configured, which is cumbersome to configure and is not conducive to management
