网络拓扑图如下
要求使用路由协议使三台PC互通，不使用静态路由
R1
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 10.1.12.1 24
[Huawei-GigabitEthernet0/0/0]int g0/0/2
[Huawei-GigabitEthernet0/0/2]ip add 10.1.13.1 24
[Huawei-GigabitEthernet0/0/2]int lo 0
[Huawei-LoopBack0]ip add 1.1.1.1 32
[Huawei-LoopBack0]q
[Huawei]rip
[Huawei-rip-1]network ?10.0.0.0
[Huawei-rip-1]network 1.0.0.0(以上为配置路由协议使三台路由器之间互通)
[Huawei]ipv6
[Huawei]int ?Tunnel 0/0/0
[Huawei-Tunnel0/0/0]ipv6 ?enable ?
[Huawei-Tunnel0/0/0]ipv6 address auto link-local（注意要在隧道口配置一个ipv6地址，不然隧道口没法正常开启）
[Huawei-Tunnel0/0/0]tunnel-protocol ipv6-ipv4（隧道协议为IPv6到IPv4 把ipv6报文封装在ipv4中）
[Huawei-Tunnel0/0/0]source ?1.1.1.1
[Huawei-Tunnel0/0/0]destination 2.2.2.2
[Huawei]int ?Tunnel 0/0/1
[Huawei-Tunnel0/0/1]ipv6 ?enable ?
[Huawei-Tunnel0/0/1]ipv6 address auto link-local
[Huawei-Tunnel0/0/1]tunnel-protocol ipv6-ipv4
[Huawei-Tunnel0/0/1]source ?1.1.1.1
[Huawei-Tunnel0/0/1]destination 3.3.3.3
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]ipv6 enable ?
[Huawei-GigabitEthernet0/0/1]ipv6 address 2001:1111::254 64（给PC1配置一个网关）
[Huawei-GigabitEthernet0/0/1]q
[Huawei]ospfv3
[Huawei-ospfv3-1]router-id 1.1.1.1
[Huawei-ospfv3-1]q
[Huawei]int ?Tunnel 0/0/0
[Huawei-Tunnel0/0/0]ospfv3 1 area 0（把隧道口加到ospfv3路由协议中，实现PC间的互访，不必配置大量的静态路由）
[Huawei]int ?Tunnel 0/0/1
[Huawei-Tunnel0/0/1]ospfv3 1 area 0
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]ospfv3 1 area ?0
[Huawei-GigabitEthernet0/0/1]q
R2跟R3的配置类似
最后用PC之间互ping测试设备的连通性
