隧道模式下IPv6穿越IPv4网络的技术分析与实现 （2）

    roueter1(config)#ipv6 unicast-routing

    roueter1(config)#interface e0/0

    roueter1(config-if)#ipv6 address 2001:250:803:11::1/64

    roueter1(config-if)#no shut

    router2(config)#ipv6 unicast-routing

    router2(config)#interface e0/0

    router2(config-if)#ipv6 address 2001:250:803:11::2/64

    router2(config-if)#no shut

    router4(config)#ipv6 unicast-routing

    router4(config)#interface e0/1

    router4(config-if)#ipv6 address 2001:250:803:12::1/64

    router4(config-if)#no shut

    router5(config)#ipv6 unicast-routing

    router5(config)#interface e0/1

    router5(config-if)#ipv6 address 2001:250:803:12::2/64

    router5(config-if)#no shut

    然后配置静态路由，没几条很简单，和ipv4的思想几乎一样。

    注意：在配的时候我们可以把R3忽略，就当R2、R4之间没有路由器，

    这样配起来会很顺啊!

    router5(config)#ipv6 route 2001:250:803:1::/64 2001:250:803:12::1

    router5(config)#ipv6 route 2001:250:803:11::/64 2001:250:803:12::1

    router2(config)#ipv6 route 2001:250:803:12::/64 2001:250:803:1::2

    roueter1(config)#ipv6 route 2001:250:803:1::/64 2001:250:803:11::2

    roueter1(config)#ipv6 route 2001:250:803:12::/64 2001:250:803:11::2

    router4(config)#ipv6 route 2001:250:803:11::/64 2001:250:803:1::1

    好了，验证一下吧

    R1 ping R5

    router1#ping 2001:250:803:12::2

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 2001:250:803:12::2, timeout is 2 seconds:

    !!!!!

    Success rate is 100 percent (5/5), round-trip min/avg/max = 48/110/216 ms

    R1 ping R4的TUNNEL1

    router1#ping 2001:250:803:1::2

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 2001:250:803:1::2, timeout is 2 seconds:

    !!!!!

    Success rate is 100 percent (5/5), round-trip min/avg/max = 36/86/216 ms

    通了
