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
