The VPN connection is provided under three service. These services are VPWS (Virtual Private Wire Service), VPLS (Virtual Private LAN Service) and VPRN (Virtual Private Routed Network). VPWS and VPLS are L2 VPN service. VPRN is Layer 3 VPN service. To sum up the services given under Alcatle-Lucent service routers, let’s check these services
layer 2 and layer 3 vpns industry leading portable mpls and ip routing solutions from metaswitch’s network technologies provide all the protocols and toolkits needed for communications equipment vendors building layer 2 and layer 3 virtual private network (vpn) services. network technologies the preferred supplier of networking software With MPLS, Layer 2 and Layer 3 VPN can be provided and main difference between MPLS Layer 2 and Layer 3 VPN from the deployment point of view is, in MPLS Layer 3 VPN, customer has a routing neighborship with the Service Provider. In MPLS Layer 2 VPN, Service Provider doesn’t setup a routing neighborship with the customer. Once a given packet is labeled the intervening devices simply forward it based on whatever LSP has been signaled. In the case of an L3VPN, the packet is a fully formed IP packet. In the case of an L2VPN a frame from a particular interface has a label added and is forwarded. Provisioning and management using a single VPN technology rather than both Layer 2 and Layer 3 is simpler. Greater Control MAC/IP provisioning from a network management system database enables programmatic network control. Control plane signaling maintains a consistent signaled forwarding database instead of flooding and learning in the data plane. Solved: Hi, I've got a choice of getting a new WAN connection but I don't fully understand the reasons for choosing a layer2 wan over a layer3 wan, can someone please explain the advantages/disadvantages of each and when to use either?
Layer 2 VPN Architectures is a comprehensive guide to consolidating network infrastructures and extending VPN services. The book opens by discussing Layer 2 VPN applications utilizing both AToM and L2TPv3 protocols and comparing Layer 3 versus Layer 2 provider-provisioned VPNs.
With MPLS, Layer 2 and Layer 3 VPN can be provided and main difference between MPLS Layer 2 and Layer 3 VPN from the deployment point of view is, in MPLS Layer 3 VPN, customer has a routing neighborship with the Service Provider.

Layer 2 and Layer 3 refer to different parts of IT network communications. The ‘layers’ refer to how you configure an IT network, and the standard for network communications called the OSI model.
The differences between Layer 2 VPN and Layer 3 VPN are as follows - Jun 30, 2020 · MPLS Pseudowire for Cable L2VPN. The Multiprotocol Label Switching (MPLS) Pseudowire for Cable Layer 2 Virtual Private Network (L2VPN) feature enables service providers to use a single, converged, Internet Protocol (IP)/MPLS network infrastructure to offer Ethernet data link layer (Layer 2) connectivity to two or more VPN customer sites. Jun 02, 2020 · In the case of security, Layer 2 VPN is less secured compared to Layer 3 VPN. Layer 2 VPN is more straightforward whereas, Layer 3 VPN is a bit harder. Layer 2 VPN is transparent to applications whereas Layer 3 VPN is less transparent. Thre are many other concepts we can introduce to define the difference between Layer 2 and Layer 3 VPN.
