实验OSPF单区域配置

【实验名称】

配置OSPF单区域

【实验目的】

配置OSPF单区域实验，实现简单的OSPF配置。

【背景描述】

拓扑图中有三台路由器，共有五个网段，并且是无类的子网。

【需求分析】

在本拓扑图中使用OSPF路由协议学习路由信息，并且使用的是单区域，所有的路由器都在区域0中。

【实验拓扑】

图8-2实验拓扑图

【实验设备】

路由器3台

【预备知识】

路由器基本配置知识、OSPF

【实验原理】

在路由器上启用OSFP进程，使用所有的路由信息通过OSFP路由协议传递。

【实验步骤】

第一步：

在路由器上配置IP地址

RA#configt

RA（config）#interfaceFastEthernet0/0

RA（config-if）#ipaddress192.168.20.1255.255.255.252

RA（config）#interfaceLoopback0

RA（config-if）#ipaddress192.168.30.9255.255.255.248

RB#configt

RB（config）#interfaceFastEthernet0/0

RB（config-if）#ipaddress192.168.20.2255.255.255.252

RB（config）#interfaceFastEthernet0/1

RB（config-if）#ipaddress192.168.10.1255.255.255.224

RC#configt

RC（config）#interfaceFastEthernet0/0

RC（config-if）#ipaddress192.168.10.2255.255.255.224

RC（config）#interfaceLoopback0

RC（config-if）#ipaddress192.168.10.33255.255.255.240

RC（config）#interfaceLoopback1

RC（config-if）#ipaddress192.168.10.65255.255.255.192

第二步：

配置OSPF

RA（config）#routerospf10

RA（config-router）#network192.168.30.80.0.0.7area0

RA（config-router）#network192.168.20.00.0.0.3area0

RB（config）#routerospf10

RB（config-router）#network192.168.10.00.0.0.31area0

RB（config-router）#network192.168.20.00.0.0.3area0

RC（config）#routerospf10

RC（config-router）#network192.168.10.00.0.0.31area0

RC（config-router）#network192.168.10.320.0.0.15area0

RC（config-router）#network192.168.10.640.0.0.63area0

第三步：

验证测试

RA#showipinterfacebrief

InterfaceIP-Address（Pri）OK?

Status

FastEthernet0/0192.168.20.1/30YESUP

FastEthernet0/1noaddressYESDOWN

Loopback0192.168.30.9/29YESUP

RB#showipinterfacebrief

InterfaceIP-Address（Pri）OK?

Status

FastEthernet0/0192.168.20.2/30YESUP

FastEthernet0/1192.168.10.1/27YESUP

RC#showipinterfacebrief

InterfaceIP-Address（Pri）OK?

Status

FastEthernet0/0192.168.10.2/27YESUP

FastEthernet0/1noaddressYESDOWN

Loopback0192.168.10.33/28YESUP

Loopback1192.168.10.65/26YESUP

用命令showiproute和shipospfneighbor来验证配置
