vlan之间的通信问题

zhouzerong

今天用Dynamipus做了VLAN实验，但为什么总是V2和V3之间的PC不能通信呢？哪位大哥给讲解一下…………


一台路由器，三台交换机，四台PC  


各个机器的 配置如下：

广播风暴

2个SW的网关地址是172.16.10.1 可是你Router 9上的 .1子接口没给配IP地址 当然不通了~~~

zhouzerong

仅仅就因为这一个问题吗 ？
还有其他的吗？

广播风暴

其他 ~~没看出来~~~

matthew

我画的拓扑？

周卿同学？(*^__^*) 嘻嘻……

matthew

周同学的配置。。。很乱。。。

不通是正常的。。。

另外。。。以后做试验最好不要用模拟器

模拟器是拿来练手的

SPOTO有真实机器

以后常来SPOTO哦
