隧道模式下IPv6穿越IPv4网络的技术分析与实现 （2）

    router2(config)#ip route 3.3.3.0 255.255.255.0 2.2.2.2

    router4(config)#ip route 2.2.2.0 255.255.255.0 3.3.3.2

    ping一下

    router2#ping 3.3.3.1

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 3.3.3.1, timeout is 2 seconds:

    !!!!!

    router4#ping 2.2.2.1

    Type escape sequence to abort.

    Sending 5, 100-byte ICMP Echos to 2.2.2.1, timeout is 2 seconds:

    !!!!!

    呵呵 都通了！

    好了，现在开始打隧道了

    分别在R2、R4上

    router2(config)#interface tunnel 0

    router2(config-if)#no ip address

    router2(config-if)#ipv6 address 2001:250:803:1::1/64

    router2(config-if)#tunnel source 2.2.2.1 （R2 e0/1）

    router2(config-if)#tunnel destination 3.3.3.1 （R4 e0/0）

    router2(config-if)#tunnel mode ipv6ip

    router4(config)#interface tunnel 1

    router4(config-if)#no ip address

    router4(config-if)#ipv6 address 2001:250:803:1::2/64

    router4(config-if)#tunnel source 3.3.3.1  （R4 e0/0）

    router4(config-if)#tunnel destination 2.2.2.1  （R2 e0/1）

    router4(config-if)#tunnel mode ipv6ip

    验证一下

    router2#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 = 52/223/376 ms

    router4#ping 2001:250:803:1::1

    Type escape sequence to abort.

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

    !!!!!

    Success rate is 100 percent (5/5), round-trip min/avg/max = 52/205/396 ms

    Ok 了
