Let’s have a look at the benefits of multi-protocol label switching, MPLS. So when did it start off? It really started off in 1998 as tag switching. Now, the tag is just another word for the label. And, later on, we just kept on using the name MPLS, so label switching. It’s really about a technique where we no longer do an IP-lookup to forward an IP packet, but we just look at a label and use that label to forward the packet. And the label lookup will happen in a special table that we will see later on. You can have one or more labels. We can just put them in a label stack on top of the IP packet. ATM, Frame Relay, X25, other WAN protocols were pretty popular back in those days so pre-2000 but they were all replaced by MPLS, which became very very popular.
Hello everyone and welcome you all to the MPLS Fundamentals Topics. I am BoT and I will be your instructor throughout this course. I will cover the basic material on MPLS so you have a thorough understanding of the architecture and functionality of MPLS. As well as the MPLS services using MPLS as a transport mechanism. By the end of this course, you should be able to understand most of the MPLS protocols and services out there.
I will be focusing on the basics in order to lay a foundation of knowledge in order for you to understand, configure and troubleshoot MPLS. This topic is not about configuring MPLS and trying to cover all aspects of it. Rather, it is to make sure you have enough information to deploy and operate any MPLS network. Enjoy.
I’ll provide some history on MPLS and how it got started. I will also go over the great benefits of MPLS, these custom main MPLS services, and why it became so popular in such a short time.
