ATEN―第十章OSPF的高级配置（4）

实验使用的工具：小凡模拟器

一、在路由器R1上，配置接口，启动ospf路由进程和rip,宣告网段，并配置路由重分发
★☆R1☆★☆→
Router>

Router#config terminal
Router(config)#hostname R1-jin
R1-jin(config)#interface loopback 0

四、在area1（R1、R2）上做非纯末梢区域，并查看路由表的变化
★☆R1☆★
R1-jin#
R1-jin#config terminal
R1-jin(config)#router ospf 1
R1-jin(config-router)#area 1 nssa
R1-jin(config-router)#end

R1-jin#show ip route
Press RETURN to get started., 1 subnets
C       1.1.1.1 is directly connected, Loopback0
C    10.0.0.0/8 is directly connected, FastEthernet0/0
C    192.168.0.0/24 is directly connected, FastEthernet1/0
R1-jin#

★☆R2☆★
R2-jin#
R2-jin#config terminal
R2-jin(config)#router ospf 1
R2-jin(config-router)#area 1 nssa
R2-jin(config-router)#end

R2-jin#show ip route
     2.0.0.0/32 is subnetted, 1 subnets
C       2.2.2.2 is directly connected, Loopback0
