路由重分发是在大型的企业中，可能在同一网内使用到多种路由协议，为了实现多种路由协议的协同工作，路由器可以使用路由重分发（route redistribution）将其学习到的一种路由协议的路由通过另一种路由协议广播出去，这样网络的所有部分都可以连通了。 为了实现重分发，路由器必须同时运行多种路由协议，这样，每种路由协议才可以取路由表中的所有或部分其他协议的路由来进行广播。那么思科Sisco路由器如何配置RIP与OSPF路由重发布？下面是具体步骤。
配置RIP与OSPF路由重发布的步骤：
1：:给R1 0/1 R2 0/1 0/0 look 0 R3 0/0 配置OSPF 放入aren1
2：给R3 0/0 look 0 R4 0/1 配置OSPF 放入aren0
3： 给R4 0/0 look 0 R5 0/0 look 0 放入 aren 2
4：给R1 0/0 look 0 R6 0/0 look 0 放入version 3
5：给R6 R1 配rip
6：给R1 R2 R3 R4 R5 配OSPF
7：实现互通
