ipv6实验

[pc3]ipv6  全局开启ipv6的功能 

[pc3]int g0/0/0

[pc3-GigabitEthernet0/0/0]ipv6 enable  再在接口下开启ipv6功能

[pc3-GigabitEthernet0/0/0]ipv6 address auto link-local  在接口开启了链路本地地址功能

协议跟接口层面都已up

[R1]ipv6

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ipv6 enable 

[R1-GigabitEthernet0/0/0]ipv6 address auto link-local

pc3上pingR1

[pc3]ping ipv6 FE80::2E0:FCFF:FE3F:755A -i GigabitEthernet 0/0/0  （-i后面接原地址的出接口，ipv6后面是R1 g0/0/0口的地址）

建立mac地址表

为PC3配置全球单播地址2001::0/64

[pc3]int g0/0/0
[pc3-GigabitEthernet0/0/0]ipv6 address 2001::1 64

PC3配置成功

配置R1

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ipv6 address 2001::3 64

R1配置成功

配置g0/0/1口

[R1]int g0/0/1

[R1-GigabitEthernet0/0/1]ipv6 enable 

[R1-GigabitEthernet0/0/1]ipv6 address auto link-local 

[R1-GigabitEthernet0/0/1]ipv6 address 2002::1 64

配置R3

[R3]ipv6 route-static 2001:: 64 2002::1

测试是否互通

配置静态路由

[PC 3]ipv6 route-static 2002:: 64 2001::1

[R3]ipv6 route-static 2001:: 64 2002::1

全球单播地址不能跨网段访问链路本地地址
