基于6PE的IPV6组播过渡技术的实现

摘要

Based on the analysis of existing transition technologies for IPv6 over IPv4,the method that uses the 6PE technology for multicast transition of IPv6 over IPv4 is put forward in this paper.According to the method,the end user device only is required to support IPv6 and the modified is required at inlet and outlet of the tunnel,on the other part of network is not required.The operators need to upgrade the PE router,but does not need to change the device configuration that is on the core of the IPv4 MPLS network.Therefore,it is a simple and efficient method for multicast transition of IPv6 over IPv4,which has a good practical value.%通过对现有的IPv4/IPv6过渡技术的分析,采用6PE技术实现了IPv4/IPv6组播过渡。对于用户端设备只要支持IPv6,只要求在隧道的入口和出口处进行修改,对其他部分没有要求;对于运营商来说只要升级PE路由器,不需要改动原有的IPv4 MPLS网络核心设备,因此是一种简单高效的IPv4/IPv6组播过渡解决方案,具有较好的实用价值。
