配置路由重分发：

IOU1：
router ospf 1
default-information originate   //重分发默认路由
exit
IOU2:
router ospf 1
redistribute rip subnets  //重分发rip路由
exit
router rip
redistribute ospf 1 metric 3   //重分发ospf路由
exit
IOU3:
router ospf 1
redistribute static subnets   //重分发静态路由
redistribute connected subnets  //重分发直连路由
exit


验证网络互通性：

查看路由表（IOU2，IOU5）：
exit
show ip route

OSPF路由重分发配置实例_redis_02

OSPF路由重分发配置实例_路由表_03


ping命令验证(IOU5)：
ping 192.168.3.1
ping 172.16.1.1

OSPF路由重分发配置实例_网络通信_04

网络通信正常，结果符合预期，配置结束。
