篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了怎么在路由器上作动态路由OSPF，实现三个网段间的主机互相ping通！！！主要说一下配置命令和网络如何搭建相关的知识，希望对你有一定的参考价值。
补充一下 需要哪些设备及接口如何连接 呵呵最好说的详细一点！！谢啦！！

参考技术A 需要高端路由器3个动态路由——OSPF高级配置 实验篇
搭建OSPF高级配置实验搭建拓扑图
在GNS 3中拓扑区域添加6台路由设别，其中一台R6路由设备作为网络运营商提供的网络设备路由，在R3路由设备中添加两块单口业务单板，分别用于连接外部网络路由与PC机；添加四台PC机与路由设备连接，其中PC3作为网络运营商的服务器设备，与R3路由设备相连。其中划分三个区域area 0、area 2、RIP；分别路由设备与PC接口处标注网段信息，如图所示：
网段划分：
192.168.10.0/24192.168.20.0/24192.168.30.0/24192.168.40.0/24192.168.50.0/24192.168.60.0/24192.168.70.0/2412.0.0.0/2413.0.0.0/24
Router ID 划分：
R2：2.2.2.2R3：3.3.3.3R4：4.4.4.4
搭建实验
1、首先在R1路由设备中添加网段地址，并设置将R1路由设备配置为默认路由。

R1(config)#int f0/0 //进入f0/0接口
