| 摘 要： | 局部的IPv6网络可以使用隧道技术通过IPv4骨干网络相互联通。入口结点将IPv6的数据分组封装入IPv4,IPv4分组的源地址和目的地址分别是隧道入口和出口的IPv4地址。在隧道的出口处,出口结点再将IPv6分组取出转发给目的站点。根据隧道端点是否支持与IPv4兼容的IPv6地址,分为配置隧道和自动隧道。根据隧道端点的不同又可分为路由器-路由器隧道、路由器-主机隧道、主机-主机隧道和主机-路由器隧道。

| Abstract: | The divided partial IPv6 networks can be interconnected via an IPv4 infrastructure by using the tunneling technology.The entry node encapsulating IPv6 packets within IPv4,the source and destination address is the IPv4 address of the tunnel's entry and exit node.Then the exit node decapsulates the IPv6 packet and forwards it on to its final destination.The two tunneling techniques,automatic and configured,differ primarily in whether they use IPv4-compatible IPv6 address at the tunnel endpoint.By the variety of the endpoint,the tunnels can fall into router-to-router tunnel,host-to-router tunnel,host-to-host tunnel and router-to-host tunnel. |
