In the VLAN aggregation technology, multiple Sub-VLANs are used to isolate wide-open domains, and these Sub-VLANs are aggregated.
Synthesizing a logical Super-VLAN, a company divides different departments into different Sub-VLANs, because Sub-VL AN not only includes physical connection, but also can establish three-layer VLAN ANIF interface, which can directly carry out three-layer communication with external network.
