路由引入-ospf、rip单向引入

1. 拓扑结构

2. 内容解析

1）将192.168.1.0、192.168.2.0、192.168.3.0 引入rip，引入到rip后，192.168.1.0、192.168.2.0、192.168.3.0​优先级为100​，而ospf自身内部192.168.1.0、192.168.2.0、192.168.3.0​的优先级为10​，所以不会产生环路

2）将192.168.4.0、192.168.5.0、192.168.6.0引入ospf，引入到ospf后，192.168.4.0、192.168.5.0、192.168.6.0的​优先级为150​，而rip自身内部192.168.4.0、192.168.5.0、192.168.6.0的​优先级为100​，所以不会产生环路

​因此单项的ospf与rip路由引入不会产生路由环路，但是存在次优路由问题​
