摘要
IPv6与IPv4共存有多种机制,但很多公司企业由于历史、经济原因以及目前的实际运营情况,不能对原有网络系统进行升级和改造。针对这种现况,利用原有网络,增加基于IPv6新子网,并基于L2TP隧道传输IPv6数据包以实现IPv6子网之间的通信。在不升级IPv4网条件下,利用NAT-PT机制完成原IPv4子网与新IPv6子网之间的互通。
IPv6 and IPv4 are currently coexisting by a variety of mechanisms. Due to the historical and economic reasons, as well as the actual operating conditions, but many companies are not able to upgrade and renovate the existing network system. In response to this current situation, new subnets is built based on IPv6 without upgrading communication between the the IPv4 network, and L2TP tunneling IPv6 packets in order to achieve the IPv6 subnets. Interoperability between the original IPv4 subnet and new IPv6 subnets is realized under NAT-PT mechanism.
