L2 VPNs

This section provides a focused explanation of Point-to-Point MPLS Layer 2 VPN technologies, including their configuration, verification, and troubleshooting. It is designed to help learners understand how MPLS can be used to extend Layer 2 connectivity between two customer sites across a service provider network. Throughout this section, learners will explore how point-to-point Layer 2 VPN services operate, how customer edge devices are connected through the MPLS backbone, and how traffic is transported transparently between locations. The training explains the role of provider edge devices, pseudowires, label exchange, and forwarding behavior in delivering reliable Layer 2 services. The section also covers the practical steps required to configure Point-to-Point MPLS Layer 2 VPNs, verify service status, and confirm end-to-end connectivity. Learners will also study troubleshooting methods for common issues such as pseudowire failures, label mismatches, attachment circuit problems, and traffic forwarding errors. By the end of this section, learners will have a stronger understanding of how Point-to-Point MPLS Layer 2 VPNs are deployed, validated, and maintained in real-world service provider environments.
