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
MPLS VPN is a family of methods for using Multiprotocol Label Switching (MPLS) to create virtual private networks (VPNs). MPLS VPN is a flexible method to transport and route several types of network traffic using an MPLS backbone. There are three types of MPLS VPNs deployed in networks today: 1. Point-to-point 2. Layer 2 (VPLS) 3.
Provider provisioned VPN. A provider-provisioned VPN (PPVPN) is a virtual private network (VPN) implemented by a connectivity service provider or large enterprise on a network they operate on their own, as opposed to a "customer-provisioned VPN" where the VPN is implemented by the customer who acquires the connectivity service on top of the technical specificities of the provider.
MPLS technologies have evolved with the strengths and weaknesses of ATM in mind. MPLS is designed to have lower overhead than ATM while providing connection-oriented services for variable-length frames, and has replaced much use of ATM in the market. [3] MPLS dispenses with the cell-switching and signaling-protocol baggage of ATM.
YANG Tools is an OpenDaylight Project toolset written in Java; Yang-Explorer - is a pyang-based Yang Browser and RPC Builder Application; ydk-gen is a YANG-to-API compiler generating APIs in multiple languages (e.g. Python, C++)
Ethernet VPN (EVPN) and Provider Backbone Bridging EVPN (PBB-EVPN) provide Ethernet multipoint services over MPLS networks. In EVPN operations, the Provider Edge (PE) routers automatically discover each other when connected on the same Ethernet segment and select a Designated Forwarder (DF) responsible for forwarding BUM traffic.

In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs.
I also substituted VPN with "service provider" because you can run a huge network with LDP, yet only have one L2VPN between two PEs.. the other LDP speakers aren't really part of that VPN. -- User:Prolixium 01:06 07 January 2012 (UTC)
