Oct 11, 2015 · Normally, I use Huawei for all sorts of CPE stuff. But this time, instead of connecting a Huawei CPE to an MPLS VPN, I thought I’d use Huawei to create the Layer 3 MPLS VPN itself. Using eNSP, the free and open Enterprise Simulation Platform, I created the following scenario: I began by configuring OSPF on the service provider routers.
Apr 12, 2017 · Internet providers who have an existing Layer 2 network may choose to use these VPNs instead of the other common MPLS VPN, Layer 3. Layer 2 VPNs uses the Label Distribution Protocol (LDP) to communicate between PE routers and established a virtual circuit providing the customer one or more private point-to-point connection. Mar 16, 2012 · MPLS Layer 3 IP/VPN Particularly suitable for vast, multi-site enterprises, i.e. retail chains, that deploy a large number of low bandwidth sites or large corporates with offices deployed globally. This type of service is a natural progression away from legacy frame relay and ATM services. 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). MPLS VPN is a type of VPN infrastructure that utilizes multiprotocol label switching techniques to deliver its services. It is a suite of different MPLS-based VPN technologies that provide the ability to utilize multiple different protocols and technologies for creating and managing communications in a VPN environment. /mpls ldp set enabled=yes transport-address=10.9.9.2 /mpls ldp interface add interface=ether3 On Router C: /mpls ldp set enabled=yes transport-address=10.9.9.3 /mpls ldp interface add interface=ether2 /mpls ldp interface add interface=ether3 On Router D: /mpls ldp set enabled=yes transport-address=10.9.9.4 /mpls ldp interface add interface=ether2
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.

MPLS because of its multi-protocol utility was of interest to Telecom, Infrastructure and Internet Service Providers due to its potential to act as an IP backbone at both layer-2 and Layer-3. The larger ISPs saw the immediate potential in layer-3 VPN as a solution, due to their extensive experience with IP routing and BGP in particular. Layer 3 MPLS VPN Service Design Overview. USCom's Layer 3 MPLS VPN service is designed to target the growing number of organizations that are outsourcing their information technology to a third-party service provider. It also targets organizations that want to move away from a traditional overlay Layer 2 VPN model (such as Frame Relay or ATM).
