静态路由综合实验

一、实验拓扑图

二、实验要求：

1、R6为ISP，接口IP地址均为公有地址，该设备只能配置IP地址，之后不能再对其进行任何配置；

2、R1-R5为局域网，私有IP地址192.168.1.0/24，请合理分配；

3、R1、R2、R4，各有两个环回IP地址；R5,R6各有一个环回地址；所有路由器上环回均代表连接用户的接口；

4、R3下面的两台PC通过DHCP自动获取IP地址；

5、选路最佳，路由表尽量小，避免环路；

6、R1-R5均可以访问R6的环回；

7、R6 telnet R5的公有地址时，实际登录到R1上；

8、R4与R5正常通过1000M链路，故障时通过100m链路；

三、实验思路

1.根据网段数并且简化路由再划分IP

2.配置DHCP服务，下发给主机IP

3.配置静态路由，使得内网全通

4.配置路由防止成环

5. 配置nat，使得公网与私网互通，

6.R6telentR5，实则登录R1

7.R4与R5正常通过1000M链路，故障时通过100m链路，即修改优先级

四、实验步骤：

分别给R1~R6配置IP地址和环回

[R1]int g 0/0/0

[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 30

Mar 21 2024 14:40:09-08:00 R1 %%01IFNET/4/LINK_STATE(l)[2]:The line protocol IP

on the interface GigabitEthernet0/0/0 has entered the UP state.

[R1-GigabitEthernet0/0/0]int g 0/0/1

[R1-GigabitEthernet0/0/1]ip add 192.168.1.5 30

Mar 21 2024 14:41:21-08:00 R1 %%01IFNET/4/LINK_STATE(l)[3]:The line protocol IP

on the interface GigabitEthernet0/0/1 has entered the UP state.

[R1-GigabitEthernet0/0/1]q

[R1]int l0

[R1-LoopBack0]ip add 192.168.1.33 28

[R1-LoopBack0]int l1

[R1-LoopBack1]ip add 192.168.1.49 28

[R1-LoopBack1]q

[R1]dis ip int b

[R1]dis ip int brief

配置R2的IP和环回：

R2]int g 0/0/0

[R2-GigabitEthernet0/0/0]ip  add 192.168.1.2 30

Mar 21 2024 14:48:07-08:00 R2 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP

on the interface GigabitEthernet0/0/0 has entered the UP state.

[R2-GigabitEthernet0/0/0]int g 0/0/1

[R2-GigabitEthernet0/0/1]ip add 192.168.1.9 30

Mar 21 2024 14:49:09-08:00 R2 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP

on the interface GigabitEthernet0/0/1 has entered the UP state.

[R2-GigabitEthernet0/0/1]

[R2]int l0

[R2-LoopBack0]ip add 192.168.1.65 28

[R2-LoopBack0]int l1

[R2-LoopBack1]ip add 192.168.1.81 28

[R2-LoopBack1]q

配置R3

R3]int g 0/0/0

[R3-GigabitEthernet0/0/0]ip add 192.168.1.6 30

Mar 21 2024 14:54:54-08:00 R3 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP

on the interface GigabitEthernet0/0/0 has entered the UP state.

[R3-GigabitEthernet0/0/0]int g 0/0/1

[R3-GigabitEthernet0/0/1]ip add 192.168.1.13 30

Mar 21 2024 14:55:36-08:00 R3 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP

on the interface GigabitEthernet0/0/1 has entered the UP state.

[R3-GigabitEthernet0/0/1]q

配置好IP地址后因为下面还有一个网段且都连接着两台主机pc1和pc2，直接用dhcp获取，所以下面就是给R3配置dhcp：

R3]dhcp en

[R3]dhcp enable

Info: The operation may take a few seconds. Please wait for a moment.done.

[R3]ip pool aa

Info: It's successful to create an IP address pool.

R3-ip-pool-aa]net

[R3-ip-pool-aa]netbios-type

[R3-ip-pool-aa]network 192.168.1.96 mask 27<
