IPv6 over IPv4 自动隧道

 实验目的：

实验环境：

        R1、R2使用Router，交换机使用S5700

实验过程

        规划拓扑图

        规划IP地址

R1：
GigabitEthernet 0/0/0             10.0.12.1
Tunnel0/0/1                       ::10.0.12.1/

R2：
GigabitEthernet 0/0/0             10.0.12.2
Tunnel0/0/1                       ::10.0.12.2/

        配置IP地址

[R1]ipv6
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ip address 10.0.12.1 24
[R1]interface Tunnel 0/0/1
[R1-Tunnel0/0/1]ipv6 enable
[R2-Tunnel0/0/1]ipv6 address ::10.0.12.1/

[R2]ipv6
[R2]interface GigabitEthernet0/0/0
[R2-GigabitEthernet0/0/0] ip address 10.0.12.2 255.255.255.0
[R2-GigabitEthernet0/0/1]interface Tunnel0/0/1
[R2-Tunnel0/0/1] ipv6 enable
[R2-Tunnel0/0/1]ipv6 address ::10.0.12.2/ 

ping测试IPv4地址连通性

[R1]ping 10.0.12.2

配置自动隧道

[R1]interface Tunnel 0/0/1
[R1-Tunnel0/0/1]tunnel-protocol ipv6-ipv4 auto-tunnel
                #配置隧道类型为自动隧道
[R1-Tunnel0/0/1]source GigabitEthernet 0/0/0
                #配置出接口

[R2]interface Tunnel 0/0/1
[R2-Tunnel0/0/1] tunnel-protocol ipv6-ipv4 auto-tunnel
[R2-Tunnel0/0/1] source GigabitEthernet0/0/0

配置IPv6静态路由使接口互通

[R1]ipv6 route-static :: 0 Tunnel 0/0/1

[R2]ipv6 route-static :: 0 Tunnel0/0/1
