A virtual network is a computer network that consists, at least in part, of virtual network links. A virtual network link is a link that does not consist of a physical connection between two computing devices but is implemented using methods of network virtualization. The two most common forms of network virtualization are protocol-based virtual networks, and virtual networks that are based on virtual devices. In practice, both forms can be used in conjunction. Virtual LANs are logical local area networks based on physical LANs. A VLAN can be created by partitioning a physical LAN into multiple logical LANs using a VLAN ID. Alternatively, several physical LANs can function as a single logical LAN. The partitioned network can be on a single router, or multiple VLAN's can be on multiple routers just as multiple physical LAN's would be. A VLAN can be on a VPN. A virtual private network consists of multiple remote end-points joined by some sort of tunnel over another network, usually a third party network. Two such end points constitute a 'Point to Point Virtual Private Network'. Connecting more than two end points by putting in place a mesh of tunnels creates a 'Multipoint VPN'.
