(woosh) - [David] In this video I'm gonna show you an application of software-defined networking using the OpenDaylight controller. In this example I'm gonna show you how to configure an OpenFlow patch panel so we're gonna create a virtual patch panel in this topology. (upbeat music) In this GNS3 topology I have four routers connected to an Open vSwitch switch. So router one has this IP address, router two this, router three this, and router four this. So router three can ping router four, but can it ping router two. At the moment we're getting a timeout. But if we do a debug ip icmp on router two and send traffic you'll notice that the traffic does get to router two, but router two can't send back the reply. If we want to make sure that these devices can't even send traffic to one another, what we will do now is add a flow entry to table zero with an ID of let's say 304, priority 1000. Matching traffic coming in on port three. We are going to output the traffic to port four. So…
