E-VPN uses the existing MPLS/IP backbone to transport the layer 2 connectivity among the various data centers which are part of same VPN. Being layer-2 extension, the solution treats the mac addresses as routable addresses and uses the existing MP-iBGP protocol to carry the customer mac addresses.
Layer 2 VPN (L2VPN) usually use MPLS-based (Multi-Protocol Label Switching) labels for sending data to network edge routers from the transmission site to the destined node. Layer 3 VPN (L3VPN) usually uses a peer-to-peer model, which uses Border Gateway Protocol (BGP) model, which is based on an IETF Request for Comments (RFC) 2547 for sending L2VPNs—Use Layer 2 transport as a building block to build a Layer 2 VPN service that includes autoconfiguration, management, QoS, and so on. A concept of pseudowires to emulate a Layer 2 service is a key attribute for a Layer 2 VPN over MPLS. Apr 15, 2009 · Layer 2 vpn is being used by many of service providers. It can be configure in two ways, one way to use l2 vpn over ip cloud with the help of l2tpv3 and another way is to use over mpls backbone by using encapsulation mpls. In this document I will be covering how to configure l2 mpls vpn over service provider cloud. Consolidated Communications' MPLS is an extremely flexible, scalable and secure WAN service with little complexity. All traffic is secured through separate routing instances and tunneling that is equivalent to layer 2 technologies. Consolidated Communications offers two service levels of MPLS-VPN to provide the best solution for your business. Mar 13, 2018 · Benefits of BGP / MPLS Layer 3 VPN. BGP / MPLS Layer 3 VPNs represent an alternative to IPSec VPNs when supporting complex topologies. They solve the scalability issue of conventional IPSec VPNs deployed in a full-mesh model, reducing the configuration overhead while interconnecting many sites. Jan 19, 2017 · Layer 2 VPN is a type of VPN mode that is built and delivered on OSI layer 2 networking technologies. The entire communication from the core VPN infrastructure is forwarded in a layer 2 format on a layer 3/IP network and is converted back to layer 2 mode at the receiving end. A Layer 2 Martini VPN is an association of Layer 2 Martini point-to-point connections. Implementation Scenarios A Layer 2 Martini MPLS VPN enables the encapsulation and transport of legacy data types over IP networks.

Apr 12, 2017 · Layer 2 VPNs are a type of Virtual Private Network (VPN) that uses MPLS labels to transport data. The communication occurs between routers that are known as Provider Edge routers (PEs), as they sit on the edge of the provider's network, next to the customer's network. At the moment, the debate between Layer 2 VPN services based on MPLS and Layer 3 MPLS VPNs is largely theoretical; Layer 2 VPN service are not widely available yet.. But the two are different
For more information on this switch, please read FS S5800-48F4S MPLS Switch: the Best Mix of Layer 2 and Layer 3 VPN vs MPLS: What’s the Difference? VPN and MPLS differ from each other not only in the above mentioned aspects but also at cost, performance, application, etc.
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). With an L2VPN service you connect with your MPLS provider at layer 2. Hence, you do not run any IP services or any routing with your MPLS provider. Hence your two remote sites being connected via this L2VPN service see each other as directly connected at L3 and you run routing protocols between your two sites.
