OSPF多区域配置

安徽工业经济职业技术学院    17#422

实验目的:

(1)实现全网互通

(2)通过操作,实现不同路由之间的转换

(3)练习OSPF多区域/单区域的配置和管理方法

实验步骤

(1) 配置PC机.路由器.服务器的IP地址

R0

R0>enable

R0#configure terminal.

R0(config)#interface FastEthernet0/0

R0(config-if)#ip address 10.0.1.254 255.255.255.0

R0(config-if)#no shutdown

R0(config-if)#exit

R0(config)#interface FastEthernet0/1

R0(config-if)#ip address 10.0.2.254 255.255.255.0

R0(config-if)#no shutdown

R0(config-if)#exit

R0(config)#interface Serial1/0

R0(config-if)#ip address 30.0.0.1 255.255.255.0

R0(config-if)#clock rate 64000

R0(config-if)#no shutdown

R1

R1>enable

R1#configure terminal

R1(config)#interface FastEthernet0/0

R1(config-if)#ip address 20.0.0.254 255.255.255.0

R1(config-if)#no shutdown

R1(config-if)#exit

R1(config)#interface Serial1/0

R1(config-if)#ip address 40.0.0.1 255.255.255.0

R1(config-if)#clock rate 64000

R1(config-if)#no shutdown

R1(config-if)#exit

R1(config)#interface Serial1/1

R1(config-if)#ip address 30.0.0.2 255.255.255.0

R1(config-if)#clock rate 64000

R1(config-if)#no shutdown

R2

R2>enable

R2#configure terminal

R2(config)#interface FastEthernet0/0

R2(config-if)#ip address 50.0.0.254 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

R2(config)#interface Serial1/1

R2(config-if)#ip address 40.0.0.2 255.255.255.0

R2(config-if)#clock rate 64000

R2(config-if)#no shutdown

(2) OPSF的开启和设置区域公布网络

R0

R0>enable

R0#configure terminal

R0(config)#router ospf 12200

R0(config-router)#net 10.0.1.0 0.0.0.255 area 1

R0(config-router)#net 10.0.2.0 0.0.0.255 area 1

R0(config-router)#net 30.0.0.0 0.0.0.255 area 1

R1

R1>enable

R1#configure terminal

R1(config)#router ospf 12200

R1(config-router)#net 30.0.0.0 0.0.0.255 area 1

R1(config-router)#net 20.0.0.0 0.0.0.255 area 0

R1(config-router)#net 40.0.0.0 0.0.0.255 area 2

R2

R2>enable

R2#configure terminal

R2(config)#router ospf 12200

R2(config-router)#net 40.0.0.0 0.0.0.255 area 2

R2(config-router)#net 50.0.0.0 0.0.0.255 area 2

实验结果:

PC>ping 50.0.0.1

Pinging 50.0.0.1 with 32 bytes of data:

Reply from 50.0.0.1: bytes=32 time=9ms TTL=125

Reply from 50.0.0.1: bytes=32 time=2ms TTL=125

Reply from 50.0.0.1: bytes=32 time=10ms TTL=125

Reply from 50.0.0.1: bytes=32 time=2ms TTL=125

Ping statistics for 50.0.0.1:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 2ms, Maximum = 10ms, Average = 5ms

设置OSPF协议有以下优点

(1) 可实现全网通的通信同时可通过更改优先级以及开销值更改路由路径

(2) 避免骨干区域压力过大 形成负载分担

(3) 每个网络有自己的区域降低了域内每个路由器的压力
