<p>A Virtual Private Network system of hybrid site and hybrid backbone network and its realizing method, relating to the Virtual Private Network technology, make the sites based on different IP versions access each other and develop VPN service through the backbone network based on different IP versions. The Virtual Private Network system of hybrid site and hybrid backbone network and its realizing method, run double routing list on CE router and PE router, configure the IPv4 and IPv6 protocol stack according to the connecting condition of CE router and PE router, perform route release and distribution after VPN addressing for VPN user sites and necessary address conversion of IPv4 and IPv6, and realize data transmission by using multi-label, thereby realize VPN in the case of hybrid site and hybrid backbone network.</p> |
