IPv6实验部分:
一. IPv6静态路由配置
实验拓扑:
IPv6 route 命令添加静态ipv6路由:
Router(config)# ipv6 unicast-routing //全局启用IPV6单播路由功能 Router(config)#ipv6 route ipv6-prefix/prefix-length {next-hop|interface} [distance]
在CISCO IOS软件支持中语法为:
Router(config)#ipv6 route ipv6-prefix/prefix-length interface link-local-address [distance]
配置R1和R2:
R1使用网络接口S1/0,通过下跳FE80::CE00:2FF:FEA4:0,可到达目的IPV6网络2001:2:2::/48
r1(config)#ipv6 route 2001:2:2::/48 serial1/0 FE80::CE00:2FF:FEA4:0 r2(config)#ipv6 route 2001:1:1::/48 serial 1/0 FE80::CE00:3FF:FE68:0 或:
r2(config)#ipv6 route 2001:1:1::/48 2001:A:A:A::1
默认路由配置例子:
r2(config)#ipv6 route ::/0 serial 1/0 FE80::CE00:3FF:FE68:0

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IPv4 Internet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:

验证IPv6 BGP4+
可以使用显示IPv6 BGP表的show bgp ipv6命令显示信息\\ipv6 BGP邻居和统计信息,这个命令相当于IPV4中的show ip bgp 命令.
