需求：是pc1，pc2，pc3直接可以相互通信，ip分別pc1:192.168.1.2 pc2:192.168.3.2 pc3:192.168.5.2
LSW1配置：
首先划分vlan，vlan中配置ip，把端口划分到vlan中，給端口配置ip，ospf宣告網段，IP段是根據子網划分的，這里划分的是192.168.2.1 255.255.255.252 30位掩碼

總結：
IP段是根據子網掩碼划分的，如果不在同一個vlan中需要用到192.168.2.0段的話 這就要划分出互聯ip，子網掩碼是252的話，就是30位掩碼，這樣划分就是一個網 絡地址一個廣播地址，剩下兩個為可用地址，如果不這樣划分，掩碼是255.255.255.0 的話，在其他vlan段中配置ip的192.168.2.0段ip的話會提示地址沖突（不同交換機） 同一設備不同的口子是直連 優先級：直連 >靜態>動態
