按理来说，我们可以从这一系列的操作中学到很多东西。

1. PC1 到 SwitchA，设置了一个 access port untagged frame 通过贴上 pvid，变成了 vlan10 tagged frame
2. SwitchA 到 SwitchB，设置了两个 trunk port 在第一个端口，`vlan10 tagged frame`与`默认的pvid 1`不同，被直接发送；在第二个端口，`vlan10 tagged frame` 属于 `allowed vlan`，所以被接收
3. SwitchB 到 PC2，设置了一个 access port 把`vlan10 tagged frame`变成`untagged frame`，再发送给 PC2

DHCP(Dynamic Host Configuration Protocol) 配置

VRRP(Virtual Router Redundancy Protocol) 配置 (目的: 让各个Host通过IP互通，并且`屏蔽掉`底层`具体的硬件端口IP地址`，从而使`一个虚拟网关`对应`多个实体硬件线路`)

![](https://2889346953-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Le4Kw7maZEabKFjsC7z%2F-Lf5hWWAPXrS6pkg310z%2F-Lf5hdGL3EnYCHpQfSPJ%2FVRRP%20configure.png?generation=1558112039410806\&alt=media)

按理来讲，我应该把所有的英文缩写变为全称。

但我发现了一个严重的问题: 这些词汇相互脱离，并没有一个总体的框架或严密的逻辑能把它们互相串联起来。那样记了也是白记。

另外，我觉得这些人上课、讲课都挺SB的，直接去看说明书、Document不是能学得更好吗？
