Embodiment Construction
[0022] Specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are for illustration only, and are not intended to limit the present invention.
[0023] figure 2 It is a structural diagram of an embodiment of a device for realizing cross-VPN mutual access in the present invention. As shown in the figure, the device of this embodiment includes: a PE device 22 connected to a CE device 21 and a firewall board 23, wherein: the CE device 21 and each VPN Binding, and connecting with user terminals belonging to different VPNs, for forwarding traffic between the user terminals and PE equipment 22; PE equipment 22, configured with multiple PE side sub-interfaces bound to each VPN, for passing The PE side sub-interface corresponding to the source VPN receives the source VPN mutual access traffic from the CE device 21 and then forwards it to the firewall board 23, and then passes the mutual visit traffic sen...

The invention discloses a device for realizing cross-virtual private network VPN mutual access, which includes a provider's edge router PE device, and the PE device is connected to a user's edge router CE device bound to a VPN with mutual access requirements, and the device also includes Including: a firewall board plugged into the PE device; among them, the PE device is configured with a PE-side sub-interface bound to each VPN, which is used to receive the source VPN from the CE device through the PE-side sub-interface corresponding to the source VPN The mutual access traffic is forwarded to the firewall board; the firewall board is used to send the mutual visit traffic back to the PE side sub-interface corresponding to the destination VPN on the PE according to the preset static route, so as to forward it to the destination VPN. The invention also correspondingly discloses a method for implementing cross-VPN mutual access by applying the device. The technical scheme of the present invention realizes cross-VPN access by using a firewall board and cooperating with PE equipment, and its configuration and deployment are simpler, and at the same time, the load pressure of the 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 ...
