Problems solved by technology

[0006] In the existing solution, the Hub needs to establish routing neighbors with each Spoke. In a large-scale network, the Hub needs to maintain a large number of routing neighbors and routing information. The system overhead is large, the routing configuration is complicated, and it is limited by the specifications of the dynamic routing protocol.

Embodiment 1

[0033] see figure 1 , figure 1 It is a schematic diagram of a DVPN large-scale networking process in Embodiment 1 of the present invention. The specific steps are:

[0034] Step 101: After the Spoke establishes a DVPN tunnel with the Hub, it sends the local downlink subnet information to the Hub through the established DVPN tunnel, and makes the Hub generate subnet routing information to the Spoke.

[0035]In this step, the establishment of the DVPN tunnel between the Spoke and the Hub is the same as the existing implementation. When sending the downlink subnet information of the local end to the Hub through the established DVPN tunnel, the packet that can rely on the established DVPN tunnel to encapsulate and forward carries the information to be sent. The specific packet implementation form and format can be based on Application-specific settings.

[0036] The subnet routing information generated by the Hub to the Spoke includes the subnet information and next-hop privat...

Embodiment 2

[0040] see figure 2 , figure 2 It is a schematic diagram of a DVPN large-scale networking process in Embodiment 2 of the present invention. The specific steps are:

[0041] Step 201, when the Spoke establishes a DVPN tunnel with the Hub, the tunnel establishment request message sent to the Hub carries the subnet information of the local end, and makes the Hub generate a subnet route to the Spoke.

[0042] Step 202, the Spoke receives the response tunnel establishment request message carrying its own and obtained other Spoke's downlink subnet information and the corresponding next-hop private network address sent by the Hub, and generates a link between the Hub and other Spokes. Subnet routing information.

[0043] In this embodiment, when the DVPN tunnel is established between the Spoke and the Hub, the request and the request message sent in response to the request carry the information to be sent.

[0044] Each Hub and Spoke in the networking by the above method obtain...

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...
