We will start with an overview of conventional routing and how it compares to MPLS routing. We will then learn about the underlying concepts, features, functions, benefits, and applications of MPLS. We will the frame-mode MPLS, the concept of MPLS labels, label stack and different label formats, the label distribution process between LSRs, the loop detection and prevention mechanisms in MPLS, MPLS architecture, MPLS VPN, MPLS QoS, and MPLS traffic engineering. We will conclude with an exploration of the future trends related to the MPLS technology.

Target audience

Those with a technical background who are familiar with data networking concepts and have the need to understand the evolving MPLS-based systems.


Routing knowledge (OSPF/IS-IS and BGP/MP-BGP) equivalent to our course IP Routing Technical.


This is a theoretical training with practical exercises.

NOTE: This course is not delivered with the FoldOut methodology.
