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. It does not provide any encryption or confidentiality by itself.

Layer 2 VPN Technology Pack Overview - Oracle A Layer 2 VPN service is a realization of a transport service used by the data networking layer. A data networking layer provides a high-level end-to-end view of the Layer 2 VPN service from a customer's perspective. The data networking layer may contain multiple transport services at a time. Layer 2 VPN vs. Layer 3 VPN : What's the Difference To put simply, Layer 2 VPNsare VPN (Virtual Private Network), which make use of MPLS labels for transporting data. Here, the communication is done between the routers, which are known as PEs (Provider Edge Routers), because it sits at the network provider’s edge, which is … Layer 2 Tunneling Protocol L2TP/IPSec VPN

Layer two VPN Making use of Enhanced 802.1Q Tunneling. 802.1Q tunneling allows support organizations to supply a Layer two VPN service, often referred to as Layer 2 transparent LAN products and services (TLS) or Ethernet LAN products and services, using a VLAN-in-VLAN hierarchy and marking the labeled packets. draft-bgbw-opsawg-vpn-common-00 - A Layer 2/3 VPN Common Introduction Various VPN-related YANG data modules were specified by the IETF (e.g., Layer 3 VPN Service Model (L3SM) or Layer 2 VPN Service Model (L2SM) ). Others are also being specified (e.g., Layer 3 VPN Network Model (L3NM) [I-D.ietf-opsawg-l3sm-l3nm] or Layer 2 VPN Network Model (L2NM) [I-D.ietf-opsawg-l2nm]). These modules have data

Offering VPN services isn't a simple Layer 2 or Layer 3 choice. If you want to implement true convergence onto a single core infrastructure, your core network should support the transport of public IP and private IP (VPN), as well as a number of legacy Layer 2 WAN and LAN technologies (for example, with Any Transport over MPLS – AtoM).

L2TP VPN usually uses an authentication protocol, IPSec (Internet Protocol Security), for strong encryption and authentication, which gives it an ultimate edge on some other most used protocols like PPTP. The L2TP protocol uses UDP ports 1701. MPLS VPNs - Layer 2 or Layer 3 | RiverStone Networks Oct 09, 2019
