Abstract

The invention discloses a large-scale DVPN networking method. The method includes: Spoke establishes a DVPN tunnel with Hub, sends its own downlink subnet information to Hub, and obtains downlink subnet information sent by Hub to itself and other Spokes and the corresponding next-hop private network address. Based on the same inventive idea, the present invention also proposes a Spoke, which improves the flexibility of DVPN networking and reduces the system overhead and routing configuration of Hub in large-scale networking.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a method for large-scale networking of a DVPN and a Spoke. Background technique

[0002] More and more enterprises have more and more demands on using the public network to establish a virtual private network (VPN), but in many cases, a branch of an enterprise uses a dynamic address to access the public network, and cannot know the public network of the opposite end in advance. address, it is difficult to establish a direct mutual access tunnel between branches. The dynamic virtual private network (DVPN) solution solves the need to establish direct tunnels between branches when the branches of the enterprise network use dynamic addresses to access the public network.

[0003] The DVPN solution consists of virtual private network address management (VAM) protocol and dynamic point-to-multipoint tunnel. The VAM protocol is the main protocol of the DVPN solution, responsible...
