实验拓扑图如下所示

配置步骤：

步骤1：配置R1接口

R1_config#ipv6 unicast-routing                              //启用IPv6路由

R1_config#in g0/4

R1_config-_g0/4#ipv6 address 2001:10::1/64           //手工配置IPv6地址        

R1_config-_g0/4#no shutdown 

R1_config#in f0/0

R1_config_f0/0#ipv6 address fec0:aaaa::1/64           // f0/0接口配置IPv6私有地址

验证：

R1#show ipv6 interfaces brief

FastEthernet 0/0 is Up, line protocol is up 

  FE80::2E0:FFF:FE26:17D1

   FEC0:AAAA::1

GigaFastEthernet0/4 is Up, line protocol is up 

2001:10::1

FE80:6::2E0:FFF:FE26:17D2

步骤2：配置R2接口

R2_config#ipv6 unicast-routing

R2_config#int g0/4

R2_config_g0/4#ipv6 address 2001:10::2/64

R2_config_g0/4#no shutdown

R2_config_g0/4#int f0/0

R2_config-_f0/0#ipv6 address fec0:dddd::1/64      // f0/0接口配置IPv6私有地址

验证：

R2#show ipv6 interfaces brief

FastEthernet 0/0 is Up, line protocol is up 

  FE80:4:2E0:FFF:FE26:17C1

   FEC0:AAAA::1

GigaFastEthernet0/4 is Up, line protocol is up 

  2001:10::2

   FE80:6::2E0:FFF:FE26:17C2

步骤3：配置静态路由

R1_config#ipv6 route fec0:dddd::/64 2001:10::2           //配置IPv6静态路由

R2_config#ipv6 route fec0:aaaa::/64 2001:10::1

上述静态路由也可以用默认路由代替，效果一样。 

R1_config#ipv6 route ::/0 2001:10::2                 //配置默认路由 ,  

R2_config#ipv6 route ::/0 2001:10::1                 //配置默认路由 

验证：查看R1路由表

R1#show ipv6 route

        is directly connected, C,GigaEthernet0/4

C      2001:10::2/128[1]

        is directly connected, L,GigaEthernet0/4

C      fe80::/10[1]

S      fec0:aaaa::/64[1]

        is directly connected, GigaEthernet0/4

C      ff00::/8[1]

        is directly connected, L,Null0

步骤4：PC机地址设置

         打开PC机的“网络连接”，右键点击“属性”，打开的“属性”窗口中选择Internet协议版本6

在IPv6地址属性页面中，配置PC机的IPv6地址信息

配置完成后，可以在CMD命令行下使用ipconfig命令（Windows 7系统）查看配置的IPv6地址

步骤5：测试连通性

         PC0可以和PC1是否三层可达
