ipv6过渡技术-IPv4 over IPv6隧道示例

实验拓扑如下：

环境概述：

PC1和PC2与路由器之间为IPv4网络。两台路由器之间为IPv6网络，通过配置，要求是PC1与PC2能互通。即使IPv4可以在IPv6网络中通信。

配置方法：

AR1：

ipv6

interface GigabitEthernet0/0/0

ip address 192.168.1.1 255.255.255.0

interface GigabitEthernet0/0/1

ipv6 enable

ipv6 address 2019:1::1/64

interface Tunnel0/0/0

ip address 10.1.1.1 255.255.255.0

tunnel-protocol ipv4-ipv6

source 2019:1::1

destination 2019:1::2

ip route-static 192.168.2.0 255.255.255.0 Tunnel0/0/0

AR2:

ipv6

interface GigabitEthernet0/0/0

ipv6 enable

ipv6 address 2019:1::2/64

interface GigabitEthernet0/0/1

ip address 192.168.2.1 255.255.255.0

interface Tunnel0/0/0

ip address 10.1.1.2 255.255.255.0
