CONSTRUCT LARGE-SCALE DVPN |
| 摘要 |
A Dynamic Virtual Private Network (DVPN) includes Virtual Private Network (VPN) Address Management (VAM) clients and a VAM server, and each VAM client includes a private gateway address, public address and subnet of the VAM client that are provided to the VAM server when registering in the VAM server. When a source VAM client receives a packet that is sent by a subnet of the source VAM client to a subnet of a destination VAM client, the source VAM client requests the VAM server to provide a next-hop address of subnet, a private gateway address, a public address and subnet of the destination VAM client to establish a DVPN tunnel between the source VAM client and the destination VAM client. |

1. A method for constructing a large-scale Dynamic Virtual Private Network (DVPN), wherein the DVPN comprises Virtual Private Network (VPN) Address Management (VAM) clients and a VAM server, and each VAM client includes a private gateway address, public address and subnet of the VAM client provided to the VAM server when registering in the VAM server, the method comprising:
when a source VAM client receives a packet that is sent by a subnet of the source VAM client to a subnet of a destination VAM client, requesting, by the source VAM client according to a destination address contained in the packet, the VAM server to parse a next-hop address of subnet, obtaining a private gateway address, public address and subnet of the destination VAM client that are sent by the VAM server according to the destination address, and establishing a DVPN tunnel between the source VAM client and the destination VAM client. |
