VLANs are used to divide a physical LAN into multiple broadcast domains to isolate services with the aim of improving the security and management of the network. Hosts within a VLAN can directly communicate only with other hosts in the same VLAN and must use a router to communicate with hosts in other VLANs.
In the network shown in Figure 1, two switc https://nox.tips/ hes are deployed at different locations, for example, on different floors of an office building. Both switches connect to two compu https://xender.vip/ ters that belong to different enterprises. In this case, the computers can be assigned to different VLANs, achieving isolation of users between enterprises.
