A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Layer 2 VPNs are a type of Virtual Private Network (VPN) that uses MPLS labels to
An MPLS VPN operates at Layer 3 and is also referred to as a BGP-VPN because multiprotocol BGP is used to transport the VPN constructs, as is discussed later in this section. The MPLS VPN architecture is based on a VPN router from the customer site (CE) and a provider edge router (PE). The service provider's backbone—specifically the provider Advantages and Disadvantages of MPLS Layer 3 VPNs MPLS Layer 3 VPNs offer an extremely scalable VPN architecture that can scale to thousands of customer sites and VPNs. MPLS Layer 3 VPNs can be offered as a managed service by a service provider to enterprise customers, or implemented by enterprises themselves to provide clear partition between business units or services.

Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered on OSI layer 3 networking technologies. The entire communication from the core VPN infrastructure is forwarded using layer 3 virtual routing and forwarding techniques. Layer 3 VPN is also known as virtual private routed network (VPRN).
