实验拓扑图

二、实验步骤

1. 配置PC机、路由器、服务器的IP地址

 - 路由器router0：
Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 10.0.1.254 255.255.255.0
Router(config-if)#no shutdown

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#exit
Router(config)#interface FastEthernet0/1
Router(config-if)#ip address 10.0.2.254 255.255.255.0
Router(config-if)#no shutdown

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

Router(config-if)#exit
Router(config)#interface Serial1/0
Router(config-if)#clock rate 64000
RRouter(config-if)#ip address 30.0.0.1 255.255.255.0
Router(config-if)#no shutdown

 - 路由器router1 
Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 20.0.0.254 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface Serial1/1
Router(config-if)#clock rate 64000
This command applies only to DCE interfaces
Router(config-if)#ip address 30.0.0.2 255.255.255.0
Router(config-if)#no shutdownRouter(config-if)#exit
Router(config)#interface Serial1/0
Router(config-if)#clock rate 64000
Router(config-if)#ip address 40.0.0.1 255.255.255.0
Router(config-if)#no shutdown

 - 路由器router2
Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface Serial1/1
Router(config-if)#clock rate 64000
This command applies only to DCE interfaces
Router(config-if)#ip address 40.0.0.2 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#
%LINK-5-CHANGED: Interface Serial1/1, changed state to up

Router(config-if)#exit
Router(config)#interface FastEthernet0/0
Router(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1, changed state to up
Router(config-if)#ip address 50.0.0.254 255.255.255.0
Router(config-if)#no shutdown

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

2. 开启OSPF并设置区域公布网路

 - 路由器router0
Router(config)#rou
Router(config)#router os
Router(config)#router ospf 100
Router(config-router)#rou
Router(config-router)#router-id 1.1.1.1
Router(config-router)#net
Router(config-router)#network 10.0.1.0 0.0.0.255 ar
Router(config-router)#network 10.0.1.0 0.0.0.255 area 1
Router(config-router)#network 10.0.2.0 0.0.0.255 area 1
Router(config-router)#network 30.0.0.0 0.0.0.255 area 1
Router(config-router)#end
Router#show running-config

三、实验结果

PC>ping 50.0.0.1
Pinging 50.0.0.1 with 32 bytes of data:
Request timed out.
Reply from 50.0.0.1: bytes=32 time=22ms TTL=125
Reply from 50.0.0.1: bytes=32 time=2ms TTL=125
Reply from 50.0.0.1: bytes=32 time=3ms TTL=125
Ping statistics for 50.0.0.1:
              Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),
Approximate round trip times in milli-seconds:
              Minimum = 2ms, Maximum = 22ms, Average = 9ms

四、实验总结

1. 通过配置OSPF协议，实现网络互联互通
2. 降低了区域内每个路由器的压力
