IPv6 over IPv4自動Tunnel:
R1配置：
[R1]undo int Tunnel 1
[R1]int Tunnel 0 mode ipv6-ipv4 auto-tunnel
[R1-Tunnel0]ipv6 address ::12.1.1.1 96
[R1-Tunnel0]source g0/1
[R1]ipv6 route-static 3:: 100 ::23.1.1.3 下一跳地址爲對端Tunnel地址
R3配置：
[R3]undo int Tunnel 1
[R3]int Tunnel 0 mode ipv6-ipv4 auto-tunnel
[R3-Tunnel0]ipv6 address ::23.1.1.3 96
[R3-Tunnel0]source g0/0
[R3]ipv6 route-static 1:: 100 ::12.1.1.1 下一跳地址爲對端Tunnel地址
