Problems solved by technology

[0005] If the number of branch nodes is too large, it will take a lot of time to obtain the routing information of all branch nodes, and the workload will be huge, resulting in low routing configuration efficiency of the central node in the point-to-multipoint GRE tunnel network.

Embodiment Construction

[0056] 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 some, not all, embodiments of the present invention. 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.

[0057] In the current routing configuration protocol, routing configuration efficiency can also be improved by configuring a dynamic routing protocol for the central node. Although it is possible to configure a dynamic routing protocol on the central node, the central node dynamically generates routes to the branch nodes through the point-to-multipoint GRE tunnel interface, thereby reducing the workload of manually configuring static routes. However, when the ...

Abstract

Embodiments of the present invention provide a route generation method, device, and system, wherein the route generation method includes: when receiving a data stream sent by at least one branch node, establishing a tunnel dynamic entry corresponding to the central node and each branch node ; Generate a static route from the central node to each branch node according to the network address information, mask information and interface information in the tunnel dynamic entry. Through this solution, the routing configuration efficiency of the central node in the point-to-multipoint GRE tunnel networking can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for generating a route. Background technique [0002] Generic Routing Encapsulation (English: Generic Routing Encapsulation, abbreviated: GRE) is a layer-3 tunneling protocol of a virtual private network (English: Virtual Private Network, abbreviated: VPN). It is a tunneling technology adopted between protocol layers, which is used to encapsulate data packets of certain network layer protocols, so that these encapsulated data packets can be transmitted in another network layer protocol. [0003] A GRE tunnel is a point-to-point virtual connection that provides a transmission path for encapsulated data packets. The network devices at both ends of the GRE tunnel respectively encapsulate and decapsulate the data packets to be transmitted. The GRE is applied as figure 1 In the shown network, it is necessary to establish multiple point-to-p...
