实验二 OSPF实验

一、拓扑图

在这里插入图片描述

二、实验要求

1.整个网络IP地址为192.168.1.0/24
2.area 0区域手工设置R1为DR R2为BDR
3.R3-R5之间使用密文方式认证
4.R1、R2、R5配上环回接，但是R5环回不能宣告
5.全网可达

三、实验分析

1.划分广播域，配置合理的IP地址
2.激活ospf，创建相应区域（看邻居表确认）
3.配置DR、BDR
4.R5环回不能宣告–做缺省

四、实验过程

1.IP分配

192.168.1.64/27----R2
192.168.1.96/27----R3
192.168.1.0/29----R1R2R3间

[R1-ospf-1-area-0.0.0.0]q

R2:

[R2]ospf 1 router-id 1.1.1.1
Info: The configuration succeeded. You need to restart the OSPF process to valid
ate the new router ID.
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 192.168.1.2 0.0.0.0
[R2-ospf-1-area-0.0.0.0]q

R3:

[R3]int GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospf dr-	
[R3-GigabitEthernet0/0/0]ospf dr-priority 0

5.R5环回不能宣告，做缺省

[R5]ospf router-id 5.5.5.5
[R5-ospf-1]area 1
