Embodiment Construction

[0128] Aiming at the above-mentioned problems in the prior art, the embodiment of the present invention provides a technical solution for automatically generating routes in a DVPN network. In this technical solution, when the VAM Client registers with the VAM Server, the registration request carries its own private network address (that is, the DVPN tunnel interface address) and network segment information, and when receiving the registration confirmation message responded by the VAM Server , obtain the private network addresses and corresponding network segments of other registered VAM Clients from the VAM Server, and generate information to other registered VAM Clients based on the obtained private network addresses and corresponding network segments of other registered VAM Clients The routing of each node in the DVPN network is realized, and the routing generation efficiency of the DVPN network is improved.

[0129] Wherein, when the VAM Client is a Spoke node, the registra...

Abstract

The invention discloses an automatic generation method for routes and a device thereof, which are applied to a dynamic virtual private network (DVPN) comprising a VPN address management (VAM) Server and VAM Clients. The method comprises the steps that a login request is sent to the VAM Server by one VAM Client, and a private network address and the corresponding network segment of the VAM Client, which are carried in the login request, are obtained by the VAM Server; and when acknowledgement information responded by the VAM Server is received by the VAM Client, private network addresses and the corresponding network segments of other already-registered VAM Clients are obtained by the VAM Client from the VAM Server, and routes of the other already-registered VAM Clients are generated according to the obtained private network addresses and the corresponding network segments of the other already-registered VAM Clients. By adopting the automatic generation method for the routes, the route of each node in the DVPN can be automatically generated, and therefore the route generation efficiency of the DVPN is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for automatically generating a route. Background technique [0002] More and more enterprises hope to use the public network to set up a VPN (Virtual Private Network, virtual private network) to connect multiple branch offices in different geographical locations. However, enterprise branches usually use dynamic addresses to access the public network, and one party in the communication cannot know the public network address of the other end in advance, which poses a difficult problem for establishing a VPN. [0003] DVPN (Dynamic Virtual Private Network, dynamic virtual private network) collects, maintains and distributes information such as dynamically changing public network addresses through the VAM (VPN Address Management, VPN address management) protocol, and solves the problem of not being able to obtain the public network address of the communication peer in ad...
