基础配置
先安装拓扑图把IP配置好，后面我们在进行OSPF的配置。为了测试效果，我们给每个路由器上面再配置一个LoopBack

二、OSPF的配置
配置之前我们先复习一下OSPF的语法：
自治区域ID：1
区域ID：1、0、2
宣告网段：省略
退出

三、查看OSPF
查看R1的整个路由表
[ar1]dis ip routing-table
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------

255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
仅查看ospf的路由
