例图：

二、需求

1.整张网络使用192.168.1.0/24网段进行划分；

2.R1、R2、R3、R4均有两个环回来模拟用户网段；

3.R5使用DHCP为PC分配IP地址；

4.R2、R3、R4、R5开启Telnet功能，账号密码：admin/admin;

5.完成所有路由器的静态路由配置，要求使用最简化路由表的方式；

6.全网可达。

三、需求分析

1.划分网段；

2.配IP；

3.配DHCP；

4.配Telnet；

5.配路由：未知网段/汇总网段；

6.缺省路由；

7.空接口路由；

8.浮动静态路由。

过程：

给r1 2 3 4 5 配IP和环回：

给r5配DHCP：

[r5]dhcp en
[r5]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[r5]ip pool aa
[r5-ip-pool-aa]network 192.168.1.160 mask 27
[r5-ip-pool-aa]gateway-list 192.168.1.161
[r5-ip-pool-aa]dns-list 8.8.8.8
[r5]int g 0/0/1
[r5-GigabitEthernet0/0/1]dhcp select global

配telent:

[r1]user-interface vty 0 4
[r1-ui-vty0-4]authentication-mode aaa
[r1]aaa
[r1-aaa]local-user admin password cipher admin privilege level 15
[r1-aaa]local-user admin service-type telnet

其他同理就不复制了

配路由：
