Problems solved by technology

[0003] However, manual creation is generally used at present. GRE tunnels need to be manually added during networking. Once new devices join the network, all network devices need to be manually added to the tunnel, which is cumbersome to use.

Embodiment Construction

[0023] The method and system for establishing a GRE tunnel in this embodiment realizes automatic creation of tunnels, realizes convenient networking, realizes interconnection between local area networks, avoids manual configuration by users, saves learning costs for users, reduces difficulty of use, and is easy to use; moreover, Created tunnels and tunnels in the tunnel blacklist are no longer created to improve efficiency, avoid wasting resources, and improve the performance of network devices.

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Network devices are divided into external network ports and internal network ports. The external network ports are used to connect with external network ports of other network devices. The physical layer is wired or wireless. The network segment whe...

Abstract

The invention discloses a GRE tunnel establishment method and system, and the method comprises the steps: enabling first network equipment to receive a data packet sent by first terminal equipment, and obtaining an outer-layer IP source address and an outer-layer IP destination address; judging whether a tunnel corresponding to the outer-layer IP source address and the outer-layer IP destination address of the data packet is created or listed into a tunnel blacklist of the first network equipment or not; if not, enabling the first network device to create a corresponding tunnel and routing rule, generating a GRE data packet, and transmitting the GRE data packet to a second network device corresponding to the outer-layer IP destination address; enabling a second network device to receive the GRE data packet and obtain an outer-layer IP source address and an outer-layer IP destination address of the GRE data packet; judging whether a tunnel corresponding to the outer-layer IP source address and the outer-layer IP destination address of the GRE data packet is created or listed into a tunnel blacklist of the second network equipment or not; if not, enabling the second network device tocreate a corresponding tunnel and routing rule. According to the invention, automatic tunnel creation is realized, and convenient networking is realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and system for establishing a GRE tunnel. Background technique [0002] Industry customers pay more and more attention to the encrypted transmission of information when using network equipment products. GRE is a relatively simple, reliable, and low-cost tunnel encryption method that can carry more types of protocol data, especially encrypted protocol data. [0003] However, manual creation is generally used at present, and GRE tunnels need to be manually added during networking. Once new devices are added to the network, all network devices need to be manually added with tunnels, which is cumbersome to use. Contents of the invention [0004] The invention provides a method for establishing a GRE tunnel, which can automatically create a tunnel and realize convenient networking. [0005] In order to solve the problems of the technologies described above, the prese...
