摘　　要：在局域网的搭建中,通常要划分多个VLAN。传统上要为每个VLAN分配单独的IP网段,每个网段拥有独立的网络地址、广播地址和网关地址,有大量的IP地址浪费。基于IP地址节约的原则,采用典型以太网拓扑,对VLAN聚合技术进行了探讨。VLAN聚合技术可以通过Super-VLAN将多个Sub-VLAN进行聚合,使多个VLAN能够共享同一个逻辑IP网段,有效地实现了以太网中IP地址的节约。In the construction of LAN,many VLANs are usually divided.Traditionally,each VLAN needs to be assigned a separate IP network segment,each segment has an independent network address,broadcast address and gateway address,so there will be a lot of IP address to be wasted.Based on the principle of IP address saving,the VLAN aggregation technology is discussed by using typical Ethernet topology.This technology can aggregate multiple sub-VLANs through super-VLAN,so that multiple VLANs can share the same logical IP network segment,effectively realizing the IP address saving in Ethernet.
