其中在R1和R5中分别设置邻居单播
R1(config-router)#neighbor 10.0.0.2
R1(config-router)#neighbor 10.0.0.3
R5(config-router)#neighbor 10.0.0.1
R5(config-router)#neighbor 10.0.0.2
最后，修改R4和R5的优先级为零
R4(config-if)#ip ospf priority 0
R5(config-if)#ip ospf priority 0
将原有的邻居单播删除。后修改为broadcast网络！

帧中继配置，与上面一样！
4.P2MA NBMA
单播指邻居，即可！
5.POINT-TO-POINT
在弹条路的的环境下，映射广播即可！
因为自己的能力有限，所以有什么问题，请求指教！395295185
