(whooshing) - [Instructor] In a previous video I showed you how to import Open vSwitch into GNS3 and I showed you some options such as viewing the flow table of the switch and the ports available on the OpenFlow switch. And I also showed you how routers connected to the Open vSwitch can ping each other because traffic is sent from the OpenFlow pipeline to the traditional pipeline. So, let's implement some policies on this Open vSwitch switch. Let's say for example that we want router one to be able to telnet to router two but not be able to ping router two. So, at the moment, router one can ping router two and that's based on this OpenFlow entry. What I'll do now is add a higher priority flow entry that matches ICMP traffic and I'm going to apply an instruction with no action. Before I add that flow to the switch, notice that router one can ping router two. This 5000 priority flow entry will take precedence over this 1000 priority flow entry, so now router one is not able to ping…
