Layer 3 VPNs (L3VPN) - Cisco MPLS Layer 3 VPNs use a peer-to-peer model that uses Border Gateway Protocol (BGP) to distribute VPN-related information. This highly scalable, peer-to-peer model allows enterprise subscribers to outsource routing information to service providers, resulting in significant cost savings and a reduction in operational complexity for enterprises. Layer 3 VPN (L3VPN) - MEF Reference Wiki - MEF Wiki These L3 services are non-standard, and there is currently no standards development organization that is attempting to create standards for such services. In contrast to L3VPN, Ethernet services are built on the concept of Ethernet based forwarding, hence can be referred to as L2VPN. When we consider L3VPN Vs. MPLS VPN - Wikipedia Layer 2 MPLS VPNs, or VPLS (virtual private LAN service), offers a “switch in the cloud” style service. VPLS provides the ability to span VLANs between sites. L2 VPNs are typically used to route voice, video, and AMI traffic between substation and data center locations. Layer 3 VPN (VPRN)

What is MPLS Layer 2 VPN and how is it different from MPLS

L2 and L3 VPN channels – the differences between physical and virtual channels of different levels Nowadays, it’s funny to recall how people were expecting an apocalypse in 2000 anxiously. It didn’t happen then; however, another important event took place. L2VPN vs L3VPN : networking VPLS although Layer 2 sits ontop of Layer 3 MPLS so if you wanted to create pseudowires between sites at any point for stuff like cross site HA or managing special routing instances e.g multicast, you can have your ISP add that functionality. Layer Networking: Layer 2 Versus Layer 3 IT Networking

I have made the following list for L2 VPN's and L3 VPN's. L2VPN: MPLS L2 VPN Using VPWS (Point-to-Point): - Virtual Leased Line (VLL) in CCC Mode - VLL in SVC Mode - VLL in Martini Mode (PWE3)/ EoMPLS - VLL in Kompella Mode. MPLS L2 VPN Using VPWS (Point-to-multipoint): - Virtual Private LAN Service (VPLS) Other types of L2VPN: - 802.1q Tunneling

MPLS VPNs: Layer 2 or Layer 3? Understanding the Choice Layer 3 and Layer 2 networks. On a Layer 3 network, asking each router on the network to potentially support thousands of different routing tables (one for each virtual private network, in addition to those of the public network) is an interminable option. Layer 2 networks, on the other hand, have a different Switch (L2/L3) Vs Router: Comparison and Differences in
