• 实验拓扑图：

• 实验需求

1、内网IP地址使用172.16.0.0/16

2、SW1和SW2之间互为备份；

3、VRRP/stp/vlan/eth-trunk均使用；

4、所有pc均通过DHCP获取IP地址；

5、ISP只配置IP地址；

6、所有电脑可以正常访问ISP路由器环回

三、配置思路：

1、划分IP网段，拓扑图中共4个网段，划分网段方式多样，上图划分方式可做参考。

2、创建eth-trunk，加入相应接口

3、创建vlan、划分vlan、trunk干道

4、MSTP

5、配置VRRP，增强设备可靠性

6、配置DHCP，并测试

7、交换机（sw1/sw2）与路由器之间的配置（IP地址及路由），这一步中的路由协议的选择看个人，静态、动态都可以实现全网通，本次实验因为路由器个数少，故我选择了配置静态路由。

8、配置NAT，做公私网的转换。

9、测试全网通

四、实验步骤：

ISP:

[ISP]int g0/0/0

[ISP-GigabitEthernet0/0/0]ip add 12.0.0.2 24

[ISP]int l0

[ISP-LoopBack0]ip add 2.2.2.2 24

[R1]int g0/0/2

[R1-GigabitEthernet0/0/2]ip add 172.16.0.194 26

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ip add 12.0.0.1 24
