Routing between VLANs
The VLAN hosts reside in their own broadcast domain and can interact /communicate quite freely. VLANs can build partition of network as well as separation of traffic at layer 2 of the OSI, and as we have discussed earlier about the need of routers, in order to host or if you want any other device to interact between VLANs, then it is essential to use layer-3 device.
The division of the LAN into multiple VLAN is basically the same like separating them into different physical LANs. In this case is clear that you will need a router if you want to go from one LAN to another.
