The video takes you through three different QoS implementation models in Cisco MPLS, namely Short Pipe, Pipe, and Uniform. We will start by examining the default QoS behavior at label imposition, and perform basic Experimental value change during label swap. We will then dive into each of the QoS models, and complete relevant configuration. Packet capture and debug will be performed throughout the lab to provide verification. Some features that you will also learn in this lab include table map and explicit null label.
