Dvpn large-scale networking and spoke

A Spoke, which is applied to a Dynamic Virtual Private Network (DVPN) large-scale networking, wherein each Hub and each Spoke in a network register to a Virtual Private Network (VPN) Address Management (VAM) server, the VAM server issues Hub information within a domain to each Spoke, the Spoke comprises a memory, and a processor in communication with the memory, the memory stores a transceiver instruction and a generating instruction, both of which are executable by the processor,

• wherein the transceiver instruction indicates to:
• establish a DVPN channel with a corresponding Hub, according to the Hub information issued by the VAM server, send subnet information about the Spoke located by the memory to the Hub, enable the Hub to generate subnet routing to the Spoke located by the memory, receive the subnet information about the Hub and another Spoke as well as corresponding private network address of next hop sent by the Hub, wherein the subnet information about another Spoke is obtained by the Hub;
• and
• the generating instruction indicates to:
• generate the subnet routing information about the Hub and the another Spoke, according to the received subnet information about the Hub and the another Spoke as well as the corresponding private network address of next hop sent by the Hub, wherein the subnet information about another Spoke is obtained by the Hub.
