从IPV4到IPV6之手工隧道

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 1.1.1.1
R2:
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

interface FastEthernet0/0
 ip address 192.168.12.2 255.255.255.0
interface FastEthernet0/1
 ipv6 address 2000::2/64
 ipv6 ospf 100 area 0

ipv6 router ospf 100
 router-id 2.2.2.2
R3:
ipv6 unicast-routing
interface FastEthernet0/1
 ipv6 address 2001::3/64
 ipv6 ospf 100 area 0
ipv6 router ospf 100
 router-id 3.3.3.3
R4:
ipv6 unicast-routing
interface FastEthernet0/1
 ipv6 address 2000::4/64
 ipv6 ospf 100 area 0
ipv6 router ospf 100
 router-id 4.4.4.4

分析：

通过在R1--R2间抓包分析

验证：
