很久没有写博文了，不知道如何开头。
最近遇到各户的三层交换机机是JUNIPER的3200，我们的矿山三大系统的接入交换机是MOXA二层。本来系统运行的好好的，忽然客户要求与他们的原有系统对接，要求我们的系统划分VLAN，可是我们的系统有几个网段，再改为一个网段的太麻烦了，也没有那么多的IP，而且WIFI手机是一直贯穿整个网络，不能做到根据端口划分VLAN。
MOXA的交换机也不支持基于IP划分VLAN，后面只能和客户商量更改他们三层交换机的设置，可是客户也不知道如何设置。没有办法，第一次接触JUNIPER的交换机，只能查资料，问客服，JUNIPER的交换机竟然可以在他们的子接口上面配置两个甚至更多的IP，突显灵感，为何不能在一个VLAN设置两个网关类。想到了就开始做，接下来附上我的配置命令（红色部分为主要）：

问题解决了，把MOXA的交换机当做傻瓜式的交换机使用。
还没有什么更好的解决方式吗？欢迎大家来讨论，一个端口下面有多个不同的VLAN，可以选择三层交换机的型号，做到基于IP来划分VLAN。
之前有个矿山，我用的H3C的交换机是用的他们的HYBIRD端口解决
