[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

[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
