GNS3 Talks: Docker, Open vSwitch, SDN and OpenFlow Part 6: GNS3 Switching Part 14

Key Takeaways

in a previous video I showed you how to import open V switch into gns3 and I showed you some options such as viewing the flow table of the switch and the ports available on the open flow switch and also showed you how routers connected to the open V switch can ping each other because traffic is sent from the open flow pipeline to the traditional pipeline what I'll do now is save the configuration of these routers and also edit network interfaces of the open V switch and uncomment these two lines Auto e zero and I face e 0 i net DHE P because I want the management interface of the switch to receive an IP address from a DHCP server I'm going to connect the switch to my physical network so I'll power down those devices and what I'll do is drag a cloud to the topology I'll run that on my local Mac Connect Ethernet is zero to the cloud so I'm going to breach the open V switch switch to my physical network so I'll start up these devices again and open up a console so ifconfig is 0 as you can see here the interface has received an IP address this open V switch switch campaign my default gateway as an example it can ping google.com but what it can also do is ping 1 I 2 1 6 8 1 1 96 which is this HP E van Sdn controller now we'll demonstrate to the integration between gns3 open V switch and open daylight in a separate video but to get us started I'm going to start off with the HP e vanity and controller so the HP vana steam controller seeing a number of switches this is actually open V switch running within genus 3 on a separate computer and these are for many net switches but on the current open V switch running in JUnit 3 I'm now going to type of this command to get to the switch to talk to the controller now before I type that command notice that the moment the switch only has one flow entry all traffic is being pointed to the normal pipeline in other words the traditional writing and switching pipeline when I press Enter and we look at the flow table you'll notice a lot of flows have been added now for some reason in this version of the HP eval you steam controller and this implementation of open V switch it's now added a crazy amount of open flow tables to the switch so when i refresh the page on the controller we can see a new switch has been added when I click on ports we can see the ports on the switch so it's Ethernet 1 2 Ethernet 15 plus the local interface we can see a summary of the switch we can see the IP address of the switch we can see the number of tables supported we can see that the switch is using open B fridge this is a switch that was developed by Anna Sarah they were purchased by VMware but open V switch is now part of the Linux Foundation they're the ports again and here the flows and for some reason it's added all these go-to statements to send flows through all the different tables on the switch so back in June is three rada one was previously able to ping rata - but that's not working since the switch started talking to the controller what I've got running on the HPE vanished in controller is flow maker deluxe this is a application that was written by northbound networks in Australia and what I'll do is add a flow entry with the priority of a thousand two table zero matching ICMP traffic and I'm going to send the traffic to the normal port and click Save so that flow entry has been added to the open flow table of the open flow switch running in June of 3 so on full thread using grep notice here's the flow entry we can see that a flow entry with a Prada of 1000 matching ICMP traffic is now being sent to the normal port so now rider one can ping Radha too and write it to contain Radha one previously we had no packets and the bytes matching that flow entry but notice now we have ten packets do the ping again now we have 20 packets matching that flow entry back on the controller previously we had two zero matches now we can see the 20 packets that matched now I could delete these additional tables table 1 table 2 table 3 and so forth but I'm simply by potting those tables with this flow entry that I've added to table 0 hope you found this video useful if you enjoyed it please like it and please subscribe to my youtube channel I wish you all the very best [Music]
