组网需求
- R1与R2之间使用静态IPv6地址互联
- R2作为DHCPv6服务器给R3的GE 0/0/0分配全球单播地址
- R4的GE0/0/0接口通过R2的RA进行无状态地址自动配置
- 配置静态路由，实现各设备之前互访
组网拓扑
配置思路
- 在R1、R2、R3、R4全局和相关接口使能IPv6功能，同时自动生成链路本地地址（Link-Local LLA）
- 在R1、R2相应接口配置静态IPv6全球单播地址
- 在R2上配置DHCPv6服务器功能，R3接口通过DHCPv6方式获取全球单播地址
- 在R2上使能发布RA报文的功能，R4通过无状态地址配置的方式获取地址
- 配置静态路由，实现各个路由器之间互访
配置命令
在全部路由器上使能IPv6，并自动生成本地链路地址
