Requirements

This course is designed to be as accessible as possible, but learners will benefit most if they have: A basic understanding of networking concepts (IP addressing, routing, subnets).
Familiarity with Cisco IOS or similar network device configuration.
Knowledge of fundamental routing protocols such as OSPF, EIGRP, RIP, or BGP.
Access to a lab environment (GNS3, EVE-NG, or physical routers) for hands-on practice.
Willingness to learn advanced service provider technologies step-by-step.
Prior exposure to MPLS basics (labels, LDP, forwarding).
If learners do not have all these skills, the course still explains concepts clearly with examples, making it approachable for motivated beginners.

Description

Are you aiming to build a career in service provider networking or preparing for certifications like CCNP Service Provider or CCIE SP? This course is designed to take you from foundational MPLS concepts to advanced MPLS L3VPN deployment skills used by top ISPs around the world. Whether you're looking to upgrade your job role, move into a service provider environment, or strengthen your resume with real, in-demand expertise, this course will guide you every step of the way.

Starting with VPN models, overlay vs. peer-to-peer designs, and MPLS basics, you’ll build a strong understanding of how modern providers deliver scalable and secure VPN services. From there, you will dive deep into MPLS L3VPN architectures, VRFs, route distinguishers, route targets, and VPNv4 propagation—skills that employers actively look for in network engineering candidates.

Through hands-on lessons covering RIPv2, EIGRP, OSPF, IS-IS, and BGP PE-CE integration, you’ll learn how real SP networks operate. You will also master advanced topics like route leaking, VRF-aware NAT, Inter-AS MPLS options, overlapping VPN scenarios, and IPv6 enablement using 6PE and 6VPE.

By the end of this course, you will have the confidence to configure, verify, and design MPLS L3VPN services just like a service provider engineer. These skills can significantly boost your earning potential, improve your chances of passing advanced certification exams, and open doors to high-demand roles in ISP, telecom, and large enterprise environments.

If you're ready to elevate your networking career, this course will give you the knowledge, confidence, and hands-on experience to get there.

Who this course is for:

This course is ideal for network engineers who want to deepen their understanding of MPLS L3VPN technologies.
Service provider engineers looking to master real-world MPLS VPN architectures and PE–CE routing designs.
Enterprise network engineers transitioning into MPLS-based WAN or hybrid network environments.
Students preparing for advanced Cisco certifications such as CCNP Service Provider or CCIE SP.
IT professionals who want hands-on, practical experience with routing protocols in MPLS VPN deployments.
Engineers seeking to understand Inter-AS MPLS designs, IPv6 enablement, and advanced SP routing features.
Anyone interested in building strong service provider networking skills through practical, scenario-based labs.
Motivated learners with basic networking knowledge who want to grow into advanced service provider roles.
