ospf多区域实例配置
需求：是pc1，pc2，pc3直接可以相互通信，ip分别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，给端口配置ip，ospf宣告网段，IP段是根据子网划分的，这里划分的是192.168.2.1 255.255.255.252 30位掩码

总结：
IP段是根据子网掩码划分的，如果不在同一个vlan中需要用到192.168.2.0段的话 这就要划分出互联ip，子网掩码是252的话，就是30位掩码，这样划分就是一个网 络地址一个广播地址，剩下两个为可用地址，如果不这样划分，掩码是255.255.255.0 的话，在其他vlan段中配置ip的192.168.2.0段ip的话会提示地址冲突（不同交换机） 同一设备不同的口子是直连 优先级：直连 >静态>动态
