配置OSPF路由协议基本功能示例

组网需求

企业用户要求不需要花费大量人力去维护网络性能，当网络中出现网络拓扑变动时，可以通过路由更新，计算出新的路由。因此需要使用OSPF动态路由协议保证网络的稳定，实现互连互通。

1、拓扑图

2、配置思路

1、接口及PC地址配置

2、OSPF路由协议配置

1、接口及PC地址配置

（PC机采用DHCP地址，路由器配置DHCP服务，为PC分配地址）

AR1路由器

<Huawei>undo terminal monitor
<Huawei>sys
[Huawei]sysname AR1
[AR1]int g0/0/0
[AR1-GigabitEthernet0/0/0]ip add 192.168.0.1 24
[AR1-GigabitEthernet0/0/0]quit
[AR1]int g0/0/2
[AR1-GigabitEthernet0/0/2]ip add 192.168.1.254 24
[AR1-GigabitEthernet0/0/2]quit
[AR1]dhcp enable
[AR1]dhcp server group 10
[AR1-dhcp-server-group-10]dhcp-server 192.168.1.0
[AR1-dhcp-server-group-10]quit
[AR1]int g0/0/2
[AR1-GigabitEthernet0/0/2]dhcp select interface
[AR1-GigabitEthernet0/0/2]quit
[AR1]

AR2省略

2、OSPF路由协议配置

AR1

[AR1]interface LoopBack 0
[AR1-LoopBack0]ip add 1.1.1.1 32
[AR1-LoopBack0]quit
[AR1]router id 1.1.1.1
[AR1]ospf
[AR1-ospf-1]area 0
[AR1-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[AR1-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255
[AR1-ospf-1-area-0.0.0.0]quit
[AR1-ospf-1]quit

AR2

[AR2]interface LoopBack 0
[AR2-LoopBack0]ip add 2.2.2.2 32
[AR2-LoopBack0]quit
[AR2]router id 2.2.2.2
[AR2]ospf
[AR2-ospf-1]area 0
[AR2-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255
[AR2-ospf-1-area-0.0.0.0]network 192.168.0.0 0.0.0.255
[AR2-ospf-1-area-0.0.0.0]quit
[AR2-ospf-1]quit

3、查看AR1路由表

（去往192.168.2.0/24网段的路由存在了，协议为OSPF）

[AR1]dis ip routing-table protocol ospf
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Public routing table : OSPF
         Destinations : 1        Routes : 1

OSPF routing table status : <Active>
         Destinations : 1        Routes : 1

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

    192.168.2.0/24  OSPF    10   2           D   192.168.0.2     GigabitEthernet
0/0/0

OSPF routing table status : <Inactive>
         Destinations : 0        Routes : 0

[AR1]

测试PC1和PC2的联通性
