Layer 2 Virtual Private Networks (l2vpn)
2. MPLS Based L2 VPNs: For an L2 MPLS VPN, the service provider is not bothered about routing and customer routes. The provider only renders a layer 2 pipe from one customer site to another over the MPLS core and customer needs to do routing configurations at his own end-devices. Mar 21, 2018 · BGP Update message sent from PE1 to PE2 is depicted in Picture 8. Notice, that there is only one MPLS header with LSP label 18, VPN label is missing. It ensures that MP-BGP message is sent via the MPLS network. VPN label is distributed inside the MP-BGP update message along with the unique VPN-IPv4 prefix. The NNM iSPI for MPLS helps you to monitor the L2 VPNs (VPLS VPN and VPWS VPN) on your network. Virtual Private LAN Service (VPLS VPN) A VPLS VPN is formed by PseudoWire VCs with the same VPN ID. In a VPLS VPN or a Layer 2 VPN, multiple sites communicate using Ethernet-based multipoint to multipoint communication over a Packet Switched Network Layer 3 and Layer 2 VPN Characteristics LAYER 3 VPNS! SP devices forward customer packets based on Layer 3 information (e.g. IP addresses)! SP is involved in customer IP routing! Support for any access or backbone technology! IP specific! Foundation for L4–7 services!! Example: RFC 2547bis VPNs (L3 MPLS-VPN) LAYER 2 VPNS! SP devices forward Jul 20, 2018 · MPLS perfectly integrates the performance and traffic management capabilities of Layer 2 switching with the scalability and flexibility of Layer 3 routing. What Is VPLS? VPLS (Virtual Private LAN Service) is a service that uses MPLS and VPN (Virtual Private Networking) to securely and seamlessly connect multiple LANs over the Internet, making

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. Yes, there are two VPN MPLS-based services: Layer 3 MPLS VPN and Layer 2 MPLS VPN. As the name indicates Layer 3 MPLS VPN operates at network Layer 3 (L3) and Layer 2 MPLS VPN operates at Layer 2 (L2) of the Open Systems Interconnection (OSI) model. This is how the two services are differentiated. Ultimately Layer 2 MPLS VPNs will allow customers to attach any layer 2 access circuit to the MPLS cloud allowing for diverse and cost effective interface options. There are multiple Layer 2 VPN service models that are being analyzed in the industry and are under consideration by various workgroups within the IETF.

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
