实验目的：

通过本实验了解两个IPV6网络穿越IPV4网络的过程

实验拓扑：

实验说明：

R1--R2之间是IPV4骨干网，R3要通过IPV4骨干网和R4通信。

配置：

R1:

ipv6 unicast-routing interface Tunnel1  no ip address  ipv6 address 2003::1/64  ipv6 ospf 100 area 0  tunnel source FastEthernet0/0  tunnel destination 192.168.12.2  tunnel mode ipv6ip interface FastEthernet0/0  ip address 192.168.12.1 255.255.255.0 interface FastEthernet0/1  ipv6 address 2001::1/64  ipv6 ospf 100 area 0 ! ipv6 router ospf 100  router-id 1.1.1.1R2: ipv6 unicast-routing interface Tunnel2  no ip address  ipv6 address 2003::2/64  ipv6 ospf 100 area 0  tunnel source FastEthernet0/0  tunnel destination 192.168.12.1  tunnel mode ipv6ip

分析：

通过在R1--R2间抓包分析

 

验证：
