cisco中IPv6实验

IPv6实验部分:

一.IPv6静态路由配置

实验拓扑:

IPv6route命令添加静态ipv6路由:

Router（config）#ipv6unicast-routing//全局启用IPV6单播路由功能

Router（config）#ipv6routeipv6-prefix/prefix-length{next-hop|interface}[distance]

在CISCOIOS软件支持中语法为:

Router（config）#ipv6routeipv6-prefix/prefix-lengthinterfacelink-local-address[distance]

配置R1和R2:

R1使用网络接口S1/0,通过下跳FE80:

静态路由配置时要注意:

在IPV6规范中,不推荐使用聚合全球单播或本地站点地址作为下一跳地址,一般使用本地链路地址作为下一跳,但在配置本地地址作为一下跳时,在配置中必须指出路由器上相应的网络接口

二.配置6to4隧道连接IPv4/6网络

6to4机制的特点是：

1、自动隧道机制

2、在站点边缘启用，6to4的路由器通过IPv4网络到达对方。

3、自动前缀分配，所有前缀均使用2002:

:

/16,IPv4的地址转换为16进制附在2002:

:

/16后面.最终表现形式是2002:

ipv4-address:

:

/48。

4、没有IPv6路由传播，每个前缀都是基于IPv4地址，因此IPv4的路由域已经足够使用。

本实验目的:

通过6to4隧道连接2个IPv6网络：

实验拓扑如下:

R4路由器连接的IPv6网络所属网段为2002:

0202:

0202:

:

/48（可划分出65535个子网）；

R5路由器连接的IPv6网络所属网段为2002:

0303:

0303:

:

/48（可划分出65535个子网）；

这两个IPv6网络之间要通信,可通过穿透IPv4Internet建立6to4隧道。

R1、R2、R3运行OSPFv2来完成整个IPv4网络的可达性；而IPv6网络分别运行OSPFv3来完成各自内部的可达性。

以下为每个路由器完整配置:
