Problems solved by technology

In addition, the establishment of traditional GRE tunnels must know the IP address of the other party, which makes it impossible for devices with dynamic IP addresses to establish GRE tunnels normally.

Embodiment Construction

[0092] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0093] The present invention provides a method for dynamically establishing a GRE tunnel, such as figure 2 shown, including:

[0094] Step s201 , the end device that needs to establish a GRE tunnel transmits the GRE tunnel information used by itself to establish the GRE tunnel, and the GRE tunnel information includes the tunnel key Key, the tunnel interface IP address and the tunnel source IP address.

[0095] Step s202, the end device judges w...

Abstract

The invention discloses a method and apparatus for dynamically building GRE tunnel. The method comprises the steps that: the end apparatus needing to build GRE tunnel transmitting the GRE tunnel information for itself to build the GRE tunnel; the GRE tunnel information comprising tunnel keyword Key, tunnel interface IP address and tunnel source IP address; the end apparatus judges whether the GRE tunnel information belongs to the tunnel built by itself according to keyword Key comprised in the GRE tunnel information in the message sent by other end apparatuses; if it is, the GRE is built according to the end-to-end apparatus tunnel interface IP address and tunnel source IP address comprised by the GRE tunnel information combining with the tunnel information and the end-to-end apparatus. Using the invention can dynamically build and maintain GRE tunnel and detect and adjust GRE tunnel state in real-time between the apparatuses in two ends of GRE under the condition that the IP address of two ends of GRE tunnel dynamically changes, which makes the building and maintenance of GRE tunnel be more flexible.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and equipment for dynamically establishing a GRE tunnel. Background technique [0002] The GRE (Generic Routing Encapsulation, General Routing Encapsulation Protocol) protocol is to encapsulate data packets of certain network layer protocols such as IP / IPX, so that these encapsulated data packets can be transmitted in another network layer protocol such as IP . The GRE protocol is essentially an encapsulation protocol, which provides a mechanism for encapsulating packets of one protocol into packets of another protocol, so that packets can be transmitted on heterogeneous networks. The channel through which heterogeneous packets are transmitted is called a tunnel. Tunnel is a virtual point-to-point connection that provides a path through which encapsulated data packets can be transmitted, and encapsulates and decapsulates datagrams at both ends of a tunnel. GRE adopts...
