METHOD AND DEVICE FOR IMPLEMENTING VPN BASED ON IPV6 ADDRESS STRUCTURE

摘要

A method and a device for implementing Virtual Private Networking based on IPv6 address structure, mostly including: firstly, the VPN local address and the VPN global address of the respective site in Virtual Private Networking VPN are set based on the IPv6 address structure; then, the route information of the respective site in VPN is established based on the set local address and the set global address, and depending on the route information, the VPN message is transferred through the respective site in VPN. Not only the VPN information can be contained in the IPv6 address, but also according to the difference of the target address prefix, the respective site can access Internet and VPN; when the autonomous system is crossed, only the route of the VPN site and the VPN group is distributed to the adjacent autonomous system.
