ospf的高级应用之rip（H3C）案例一

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2.拓扑图

[Quidway-Vlan-interface20]quit
[Quidway]ospf  //模式请注意：
[Quidway-ospf]area 2  //进入要宣告网络的区域
[Quidway-ospf-area-0.0.0.2]network 192.168.1.0 0.0.0.255  //宣告网络
[Quidway-ospf-area-0.0.0.2]network 192.168.2.0 0.0.0.255

[R3-Serial0]int e1
[R3-Ethernet1]ospf enable area 2
路由器R10的配置：
[R10]int s0
[R10-Serial0]ip address 192.168.3.2 24

[r10-Serial0]undo shutdow
路由器R5的配置：
[R5]int s1
[R5-Serial1]ip add 192.168.4.2 24
[R5]int loo 1  //由于未接线，所以设置loopback 接口
[R5-LoopBack1]ip add 192.168.8.1 24  // 主地址
[R5-LoopBack1]ip add 192.168.9.1 24 sub  //配置辅助IP地址 (为了实现路由汇总)

[R5-LoopBack1]ospf enable area 1
[R5]int s1
[R5-Serial1]shut
[R5-Serial1]undo shut
路由器R9的配置：
[Router]sysname r9
[r9]int e1
[r9-Ethernet1]ip add 192.168.5.2 24
[r9-Ethernet1]int s0
[r9-Serial0]ip add 192.168.6.1 24
[r9-Serial0]qu
[r9]rip  //启用rip协议
waiting...
RIP is running

[r12-Serial0]int e1
[r12-Ethernet0]ip add 192.168.7.1 24
[r12]rip
waiting...
RIP is running
[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
