R1、R2运行RIPv2，R2、R3运行OSPF。R1上开设三个Loopback接口；R1并没有在这三个接口上激活RIPv2。
2.网络需求
a.R1在RIP视图中只使用network命令激活GE0/0/0接口，而三个Loopback接口不能激活RIP，要求R2能够通过RIP学习到除了192.168.3.0/24路由之外的其他两条Loopback路由；
b.在R2上部署路由重发布，将RIP路由注入到OSPF使得R3能够学习到192.168.1.0/24及192.168.2.0/24这两条路由，同时要求192.168.1.0/24这条路由在R3的路由表中度量值显示10，而192.168.1.0/24这条路由在R3的路由表中度量值显示20，两条外部路由类型均为Type2。
c.要求R3能够访问192.168.1.1及192.168.2.1。
3.配置
当使用ACL来抓取路由时ACL的书写方法，例如要抓取192.168.1.0/24这条路由，ACL的规则是“rule permit source 192.168.1.0 0.0.0.0“，通配符不是0.0.0.255而是0.0.0.0，这是因为基本ACL在匹配路由时，只能匹配路由的网络号，而无法匹配路由的掩码，因此通配符写成0.0.0.0，表示精确匹配192.168.1.0这个网络号。

4.查看路由注入情况因为配置了路由策略所以192.168.3.0/24网段没有被注入
