一、划分vlan
pc1/3属于vlan2 pc2/4/5/6分别属于vlan3，4，5，6且处于同一网段，无法使用就supervlan来实现、于是需要利用路由器来直接分发ip，但是不同的vlan不能使用同一个接口，于是将物理接口给vlan 3 4 5 6因为他们虽然不属于同一vlan但是属于同一个网段，子接口就给vlan2。
二、划分T,U
根据要求pc1可以连通pc2 4 5 6 则U应为2 3 4 5 6
pc2连通pc1 3 4 5 6则U为2 3 4 5 6
pc3连通pc2 4 5 6则U为2 3 4 5 6
pc4连通pc1 2 3 5但没有pc6则U为2 3 4 5
pc5连通pc 1 2 3 4则U为2 3 4 5
pc6连通1 2 3则U为 2 3 4
三、开始大概的编写 里lsw1
按照要求将pc1 3 化为acces
将交换机和路由器的接口放行
