Abstract

The invention discloses a device for realizing mutual access of crossing virtual private networks (VPN) comprising PE equipment of a provider edge router; the PE equipment is connected with CE equipment of a user edge router which has mutual access requirement and is bonded by VPN; the device also comprises a firewall board card inserted on the PE equipment, wherein the PE equipment is configured with a PE side subinterfaces bond to all VPNs, and is used for receiving source VPN mutual access flow from the CE equipment by the PED side subinterface corresponding to the source VPN and forwarding the source VPN mutual access flow to the firewall board card; the firewall board card is used for sending the mutual access flow back to the PE side subinterface corresponding to the target VPN on the PE according to a preset static router so as to forward to the target VPN. The invention also discloses a method for applying the device to realize mutual access of crossing virtual private networks correspondingly. The technical proposal adopts the firewall board card to match with the PE equipment so as to realize access of crossing virtual private networks, the configuration and allocation are simpler, and simultaneously the load pressure of equipment is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of VPN (Virtual Private Network, virtual private network), in particular to a device and method for realizing cross-VPN mutual access. Background technique [0002] At present, VPN networking is more and more widely used in the private network architecture of finance, electric power, government, education and other industries. In the multi-VPN networking structure including public VPN appearing in these applications, cross-VPN access is inevitable. [0003] There are generally two ways to achieve cross-VPN mutual access in the prior art. One is to configure the multi-role host function on the PE (Provider Edge Router) device and combine the static routing VPN penetration technology to achieve mutual access. The following is Take the traffic forwarding process from local VPN-A to remote VPN-B as an example to illustrate: [0004] First, deploy the multi-role host function under the interfaces of the ...
