IPv6地址自动配置中接口ID的生成算法

Generating Algorithm of Interface ID in IPv6 Address Auto-configuration

IPv6协议的一大特点是支持主机和路由器的地址自动配置,典型的IPv6单播地址由全局路由前缀、子网ID和接口ID组成。其中,全局路由前缀和子网ID可以通过路由通告得到,接口ID的自动生成在无状态地址自动配置方式中是非常重要的。本文给出了由MAC地址转换成接口ID的EUI-64转换算法。

A typical IPv6 unicast address is composed of global route prefixsubnet ID and interface ID.Interface can get its gloabal route prefix and subnet ID through Router Advertisement message.Sothe automatical creation of the interface ID is very important for stateless address auto-configuration.This paper introduces the methodwhich creates interface ID from MAC address.
