ISIS在IPV6中的应用

拓扑图拓扑图

?实验目的：

熟练掌握IPV6与IPV4的在ISIS协议下各种模式如何使用，并且能根据实验要求完成各项指标。

实验要求

1.各个相连链路的接口ipv4地址按：XY.1.1.X/Y--/24位掩码的方式配置，各路由器的环回口地址按：X.X.X.X/32形式配置。

2.各个相连链路的接口ipv6地址按：2001:XY::X/Y--/64位掩码的方式配置，各路由器的环回口地址按：2002::X/Y--/128位的方式配置。

3.R1配置在47.0123的区域内，R2.R3,R4 配置在47.0234区域内，各路由器的系统ID按：XXXX.XXXX.XXXX.或者YYYY.YYYY.YYYY的形式配置

4.R1配置在ISIS Level-2的级别，R2.R3配置在ISIS Level-1-2的级别，R4配置在ISIS Level-1的级别。

5.通过修改R4接口下COST值的方式，使得IPV4到达R1的路由走R3，IPV6 的路由走R2.

实验步骤：

1.配置各路由器的相连接口的IP地址

2.配置各路由器的ISIS进程

3.配置各路由器接口下开启isis进程
