Abstract: |
The method includes following characters: setting up filtering module of pseudo IPv6 route at router on network boundary in charge of route interaction of interlinked networks between IPv6 network of this ISP and IPv6 of other ISPs in order to prevent pseudo IPv6 route from entering into other IPv6 networks; setting up filtering module of 4over6 route at all 4over6 router on boundary between IPv4 network inside this ISP and IPv6 network inside this ISP in order to make 4over6 conversion mechanism prevent conversion from IPv4 route not belonging to this ISP to pseudo IPv6 route. Through combined action of the said two modules, 4over6 conversion mechanism can be deployed without need of support from whole network. Based on practical situation, each ISP can deploy the conversion mechanism stringendo so as to enhance realizable property as well as reduce spending on implementing 4over6 conversion mechanism. |
