traffic engineering

The video takes you through the concept of Cisco MPLS Traffic Engineering (TE) metric. We will first get to know the two types of metric; IGP and TE. We will then focus on the two common forwarding options; Autoroute Announce and Forwarding Adjacency, as you will see that depending on which forwarding option you are using, the path metric gets calculated and manipulated differently which directly effect traffic routing decision. We will try to exercise our knowledge by attempting to load balancing traffic between IP path and TE tunnel.

The video demonstrates and compares various traffic forwarding options in Cisco MPLS Traffic Engineering (TE). Since MPLS TE is based on a tunnel interface, the two obvious options are static route and Policy Based Routing (PBR). The other two available options, which we will look at more extensively at their characteristics, are Autoroute Announce and Forwarding Adjacency. We will investigate how these forwarding options cause the tunnel to be seen by routing protocol and effect the router routing decision.

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.

The video gets you started on Cisco MPLS Traffic Engineering (TE). We will look at the fundamental of MPLS TE including routing protocol, specifically ISIS, metric support, additional routing information the protocol needs to carry, and the role of Resource Reservation Protocol (RSVP) in bandwidth reservation, MPLS label distribution, and tunnel establishment. As a quick demonstration, we will configure a basic MPLS TE tunnel, perform Wireshark packet capture, and review RSVP packets.
