VPLS – Virtual Private LAN Service
(VPLS) is a Layer 2 VPN (Virtual Private Network) technology that allows the creation of a virtual LAN across a wide area network (WAN).
It provides an extension of the Layer 2 network across the WAN, allowing the customers to connect their LANs at different locations and appear as a single bridged LAN. VPLS uses MPLS (Multiprotocol Label Switching) for forwarding and label switching.
