在R3上看路由





首先做末节区域
我们只要在要定义的末节区域的每个路由器上在路由配置模式下都输入
area 区域号 stub命令

R2
router ospf 1
area 2 stub

R3
router ospf 1
area 2 stub
再看路由



完全末节区域
完全末节区域是思科特有的功能，他可以阻止3,4,5类的LSA通告到区域
完全末节区域，我们在区域内的除了ABR路由器的每个路由器配置好
area 区域号 stub 然后再在ABR路由器上配置 area 区域号 stub no-summary



R2
router ospf 1
area 2 stub no-summary

R3
router ospf 1
area 2 stub

路由就好简单的
