ospf的高级应用之rip！（H3C）

案例一：

1作业要求：

• 把rip学到的路由重分发到ospf中
• 在rip中注入默认路由指向ospf
• 实现路由汇总(在ABR上汇总)
• 配置末梢区域
• 配置完全末梢区域

[r12-rip]network 192.168.6.0

[r12-rip]network 192.168.7.0

[r12]int s0                               //该接口复位，否则不通

[r12-Serial0]shutdown

[r12-Serial0]undo shutdow

 

5.路由重分发：

[R10]ospf enable

[R10-ospf]import-route direct    //发布直连路由

[R10-ospf]import-route rip        //把rip学到的路由信息发送到OSPF中

[R10]int null 0                        //必须先创建NULL0

[R10]ip route 0.0.0.0 0 null 0     //用一条默认路由指向该接口，表示：通过该接口的路由都扔掉

[R10]rip

[R10-rip]import static              发布静态路由

查看路由表信息如下：

[r9]dis ip rout
