Logical View of a Layer 2 MPLS VPN. A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Layer 2 VPNs are a type of Virtual Private Network (VPN) that uses MPLS labels to transport data. The ...

This document describes the Multiprotocol Label Switching (MPLS) based L2 Virtual Private Network (L2VPN) pseudowires.

L2VPN and an associated native Layer-2 service. The L2VPN WG scope includes the following: Discovery of PEs participating in a Layer-2 VPN and the associated topology required for connectivity of the VPLS, VPWS, VPMS or E-VPN service. Signaling of information related to the discovery and membership of PEs within a L2VPN. These procedures must

Coordination between the service provider and customer is necessary while establishing an L2VPN network. The service provider connects Layer 2 devices and the customer uses the service provider's data link resources to create their own network.

Virtual Private Wire Services (VPWS), also known as Ethernet over MPLS (EoMPLS), allow two L2VPN Provider Edge (PE) devices to tunnel the L2VPN traffic over an MPLS cloud.

When you remember that both L2VPN and L3VPN are advertised via BGP, it makes sense that we’d have these elements in the config. We’re also defining this as an instance-type of “l2vpn”, and we’re putting the relevant interface into this routing-instance.

A Layer 2 virtual private network (L2VPN) provides MPLS-based L2VPN services to transparently transmit Layer 2 user data over tunnels on an MPLS network. This reduces the number of label switched paths (LSPs) maintained by transit nodes.
