[Quidway-Vlan-interface20]quit

[Quidway]ospf //模式請注意：

[Quidway-ospf]area 2 //進入要宣告網絡的區域

[Quidway-ospf-area-0.0.0.2]network 192.168.1.0 0.0.0.255 //宣告網絡

[r12-rip]network 192.168.6.0

[r12-rip]network 192.168.7.0

[r12]int s0 //該接口復位，不然不通

[r12-Serial0]shutdown

[r12-Serial0]undo shutdow

5.路由重分發：

[R10]ospf enable

[R10-ospf]import-route direct //發佈直連路由

[R10-ospf]import-route rip //把rip學到的路由信息發送到OSPF中

[R10]int null 0 //必須先建立NULL0

[R10]ip route 0.0.0.0 0 null 0 //用一條默認路由指向該接口，表示：經過該接口的路由都扔掉

[R10]rip

[R10-rip]import static 發佈靜態路由

查看路由表信息以下：

[r9]dis ip rout
