Intra-AS MPLS L3VPN

This course provides a comprehensive and practical understanding of implementing Layer 3 VPNs, commonly known as L3VPNs, within modern service provider networks. It is designed to help learners understand how L3VPN services are configured, delivered, verified, and troubleshot across MPLS and Segment Routing-based infrastructures. Throughout this course, you will learn important L3VPN concepts and deployment models, including Inter-AS options, shared services, extranet connectivity, internet access integration, and L3VPN service auto-steering into Segment Routing policies. These topics help learners understand how service providers deliver scalable, secure, and flexible connectivity to customers across complex network environments. This section also focuses on the configuration, verification, and troubleshooting of MPLS Layer 3 VPNs. Learners will explore how Provider Edge devices connect with Customer Edge routers and how PE-CE routing is implemented using protocols such as BGP, EIGRP, and OSPF. The training explains how routing information is exchanged, separated, and transported across the MPLS backbone using VPN routing and forwarding concepts. By completing this course, learners will gain practical knowledge of L3VPN architecture, PE-CE routing design, MPLS VPN operation, and service provider troubleshooting methods. This course is especially useful for candidates preparing for the CCIE Service Provider v5 Lab exam, professionals working in service provider environments, and anyone who wants to deepen their understanding of service provider infrastructure and advanced VPN service delivery.
