1.1.1 关于本实验
本章主要阐述如何在一台路由器上同时运行两个不同的OSPFv3进程，并实现路由互通的过程。
1.1.2 实验目的
掌握配置OSPFv3双进程路由互通。
1.1.3 实验组网介绍
1.1.4 实验规划
在R1、R2和R3上启用OSPFv3路由协议。R1和R3间运行OSPFv3 2，R2和R3之间运行OSPFv3 3两个不同进程，实现两个PC可以互相通信。
1.2 实验任务配置
1.2.1 配置思路
1. 配置PC1、PC2、R1、R2及R3的IPv6地址，使直连设备可以进行相互通信；
2. 在R1、R3上配置OSPFv3 2进程，在R2、R3上配置OSPFv3 3进程；
3. 在R3上的两个OSPFv3进程分别引入另一组OSPFv3进程，使得整个网络互通，PC1能够与PC2互访。
