typically with routers and vlans. The concept is that you use a router to route between vlans:
Example:
192.168.1.0 = vlan 1
Router: 2 interfaces that each are in vlan 1 and vlan 240
192.168.240.0 = vlan 240
The vlan numbers do not have to match the octets, just good to label the vlans to match the network ID for quick visualization of what subnet is on what vlan. VLANs are Virtual Local Area Networks that are used for network segmentation. The router is used to route between vlans, and a router is needed due to the fact that hosts in one vlan can not communicate with hosts in another vlan; this is typically the configuration consists of dot1q encapsulation (Tagging Ethernet frames with vland IDs) Depending on what type of equipment you have will dictate what you can do.
