实验拓朴:

 

 

 

实验目标:

 

目标1.  按照实验要求连接拓扑

目标2.  配置VTP域：SWITCH1、SWITCH2为VTP SERVER并开启VLTP修剪；SWITCH3、SWITCH4为VTP CLIENT；并在SERVER上创建VLAN2、3、4     

目标3.  将SWITCH1配置为VLAN1、VLAN3的根桥，VLAN2、VLAN4的次根桥
              将SWITCH2配置为VLAN2、VLAN4的根桥，VLAN1、VLAN3的次根桥

目标4.  在VTP CLIENT上将接口配置进正确的VLAN

目标5.  配置SWITCH1和SWITCH2之间的以太网通道

目标6.  在SWITCH1、SWITCH2、ROUTER1上配置RIP路由协议

目标7.   测试网络联通性：VLAN内PC连通性；VLAN间PC连通性；VLAN内PC与INTERNET连通性

分析：很明显，VLAN 这次的显示和第一次的有些不同，接口划分到VLAN 中后，它们的端口所属也在发生变化，但是，不变的是，它们一直都是处于转发状态。

 

4.测试相同VLAN中的主机是否能够通信.

 

 

 

 

分析：

由此可见，相同VLAN 不同交换机的VALN是可以PING 通的了。不 同VALN 之间目前还是不能PING 通。
