在现实的网络中，网络的连接是依靠链路协议链接的，可是协议却各不相同，没法直接连接使用，我们在现实中常见的协议是rip协议和ospf协议。今天的实验就是讲将这两个协议联合使用。
实验说明：本实验做的是ospf路由与rip路由的连接，因为两者是不同的协议，没法直连，假设ospf是一个大型的网络区域。rip是个很小的网络区域，那么我们可以把rip重发布到ospf，将rip直连到ospf。
按照上图配置相应的端口和路由协议

现在rip和ospf都配置好了，只差把rip和ospf连接了
在r2里
进入ospf 1 对rip进行重发布
[Huawei]ospf 1

OK！证明我们的实验完全没有问题，rip和ospf已经形成了链路
