R3(config-router)#redistribute ospf 1 metric 3
R3(config-router)#exit
R3(config-router)#redistribute rip subnets
<b>3.</b><b>查看各路由器的路由表</b>
①R1
②R2
③R3
④|R4
<b>4.</b><b>配置路由汇总</b>
①在R1（ABR）上配置区域间汇总
R1(config-router)#area 1 range 172.16.0.0 255.255.255.252
②在R3（ASBR）上配置外部路由汇总
R3(config-router)#summary-address 10.0.0.0 255.255.248.0
5.查看各路由器的路由表，与步骤3进行比较
