VLAN和MAC地址的分析以及交换机和ARP的问题
交换机包转发范围：我们认识交换机是能够区分vlan的，所谓mac地址学习，其实是在同一个vlan里边的概念（遭到播送原理的影响），能够这样说——mac地址表的构建是基于vlan来的。说白了，交换机的包转发是2层转发，我们区分了vlan，vlan之间的包转发即是三层概念了。_rels\.rels
(Switch packet forwarding range: We know that switches can distinguish vlans. The so-called mac address learning is actually a concept in the same vlan (affected by the broadcasting principle). It can be said that the construction of the mac address table is based on vlan come. To put it bluntly, the packet forwarding of the switch is layer 2 forwarding. We distinguish VLANs, and the packet forwarding between VLANs is the concept of layer 3.
