动态路由中OSPF多区域的配置_第1张图片
实验拓扑图


1. 实现全网的互通。

2. 通过更改优先级,实现不同路由之间的转换。

实验步骤:

1.开启端口

Router0:

Router>enable

Router#config terminal

Router(config)#hostname R0

R0(config)#interface f0/1

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 f0/1

R0(confif-if)#ip address 10.0.1.254 255.255.255.0

R0(config-if)#no shutdown

R0(config-if)#exit

R0(config)#interface S0/1

R0(confif-if)#ip address 20.0.0.254 255.255.255.0

R0(confif-if)#no shutdown

Router1:

Router>enable

Router#config terminal

Router(config)#hostname R1

R1(config)#interface f0/0

R1(config-if)#ip address 30.0.0.254 255.255.255.0

R1(config-if)#exit

R1(config)#interface s1/0

R2(config-if)#ip address 20.0.0.2 255.255.255.0

R1(config-if)#no shutdown

R2(config-if)#exit

R2(config)#interface s1/1

R2(config-if)#ip address 40.0.0.1 255.255.255.0

R2(config-if)#no shutdown

Router2:

Router>enable

Router#config terminal

Router(config)#hostname R2

R2(config)#interface f0/0

R2(config-if)#ip address 50.0.0.2 255.255.255.0

R2(config-if)#no shutdown

R2(config-if)#exit

R2(config)#interface s1/1

R2(config-if)#ip address 40.0.0.2 255.255.255.0

R2(config-if)#no shutdown

2. 配置时钟频率及OSPF路由配置:

R0:

R0(config)#interface s1/0

R0(config-if)#clock rate 64000

R0(config-if)#extit

R0(config)#router ospf 100

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

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

R0(config-router)#network 20.0.0.0 0.0.0.255 area 1

R1:

R1(config)#interface s1/0

R1(config-if)#clock rate 64000

R1(config-if)#extit

R1(config)#interface s1/1

R1(config-if)#clock rate 64000

R1(config-if)#exit

R1(config)#router ospf 200

R1(config-router)#network 30.0.0.0 0.0.0.255 area 2

R1(config-router)#network 40.0.0.0 0.0.0.255 area 3

R1(config-router)#network 20.0.0.0 0.0.0.255 area 1

R1(config-router)#network 50.0.0.0 0.0.0.255 area 3

R2:

R2(config)#interface s0/0

R2(config-if)#clock rate 64000

R2(config-if)#extit

R2(config)#interface s1/1

R2(config-if)#clock rate 64000

R2(config-if)#exit

R2(config)#router ospf 300

R2(config-router)#network 40.0.0.0 0.0.0.255 area 3

R2(config-router)#network 50.0.0.0 0.0.0.255 area 3

R2(config-router)#end

R2#show ip route

3. 实验结果:

PC>ping 30.0.0.1

Pinging 30.0.0.1 with 32 bytes of data:

Request timed out.

Reply from 30.0.0.1: bytes=32 time=22ms TTL=125

Reply from 30.0.0.1: bytes=32 time=2ms TTL=125

Reply from 30.0.0.1: 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

4.个人总结:

1. 首先ospf进程号两边要相同;

2. 两边接口的地址要在同一网段;

3. 宣告网段时要注意带反掩码进行匹配,后面跟上区域号;

4. 其次ospf区域要注意划对
