单臂路由与三层交换作用及基础配置

时间  2020-12-30

             首先我们要了解，单臂路由的局限性以及缺点。
        说到缺点就要简单介绍一下单臂路由的优点，单臂路由的优点就是省钱。

=================================================================================        单臂路由为骨干网络链路，容易形成网络瓶颈。
             子接口依托于物理接口，应用不灵活。

                     接下来我们来了解一下三层交换机的知识及配置：
                         三层交换机=二层交换机+三层转化
                         其目的是使VLAN之间实现网络通信
