The video demonstrates two methods of specifying traffic path in Cisco MPLS Traffic Engineering (TE); Explicit and Dynamic Path. We will first look at Dynamic Path and its ability to automatically calculate the shortest path to tunnel destination router even routing around a failed link. We will then touch on the concept of tunnel re-optimization and adjusting its timer. You can also gain complete hop-by-hop control of the traffic path by using an Explicit Path option, which we will review in the second half of the video.
