Openvswitch Use in Openstack - Openstack bridges (br-int, br-ex, br-tun)

a little good day to you friends so today I'll be speaking you know on the topic of OpenStack administration and all the components that I'll be describing to the open V switch open this which is a very important component you know in OpenStack you know which as a postdoc is today you know it is difficult you know to talk about core stuff without you know talking about pull the switch or open V switch is a let's go to the let's go to the open fridge now website so basically you see something like openness which is a production quality multi-layer you know multi-layer virtual switch in on life changed under the open source Apache 2.0 license so it is a virtual switch as you can see and it you know it supports it also standard some protocol so it is used a lot in OpenStack aside like I said it is difficult to talk about the stuff you know without talking about open V switch so awful I'll also be speaking about three major bridges in OpenStack you know if you are doing with a postdoc you should be familiar with this preachy or the first among them is the BR spawn you know it is a tunnel bridge so it can implement either the a clam or GRE the second one is the integration bridge so the integration bridge is the actual bridge that is used for the virtual machine and the VXR is the external bridge it is the bridge you know that is used to connect to the outside world so you know if you have you know followed my series about optical description when I talked about installation your I think you should remember this particular bridge BRX you notice the one that allows you to connect you know to astana water so let me show you them on this the diagram so to buttress my point food are to this so this dozen you know shoes a basic talks textual the couple started talking so for example I see you as a virtual machine oh this is state zero not virtual machine you know is cone is connected to PR int all the BR rings like I said is the integration bridge all other virtual machines also connected to the same bridge so the beer ink is connected to the BR tone or bridge to the dial tone you know the issues for tunneling so tunnel into the tunnel so you see from G to H is a tunnel it can be GRE tunnel it can be if V excellent one L so this architecture you know shows you when you have all the compute off or the compute separated from the the network node so this is the network node here this is the compute node to food or the be a strong issues you know Al's integration authority beyond stone is used as the tunneling bridge between the compute node on the network node so also you see another they are links on the network load on the BR in you are the DHCP agent and the on the router in connected here which is you know connected to PR h BR x is you know the bridge that allows you to connect to i stand our through if you if you want to wait if you want to be solid you know in OpenStack administration you have to be familiar with these three bridges during their turn and B Eric and all of them they are implemented in open V switch so let me go to the terminal and I will show you so this is my terminal arm so if you are in the mold know the environment you you go to your network mode oh and also your call your computer note so this environment is a only one but also show you so open this which you can interact with open research by using the open v8 authoring ODS or obvious vs coder and if I kept obviate the CTL show it will shows me the you know the motifs are contained in the Bundy open research right now who like I said you see the first bridge a is we are taught is a bridge so you know you have to imagine what the bridges have a breach and your ports connected to the bridge is like a physical switch where you have a physical switch the has port and I plug in the rj45 so what this implements it in a bachelor you know this is a software equivalent of a physical switch so you the PR Tron or we have the BR int and the PR x over here BR e X so the BR eak is you know allows you to connect the outside world can you see the open or open this which version you know it somewhere down here soon this gives you basically the summary of everything that is contained in the open in the networking of OpenStack as it is so or bearings you see the bearings has a lot of ports you know connected to it because like I said Libya range is the one that you know the virtual machines connect to and not only the virtual machine but also the DHCP port and the under routing the Russian agent and the disappearance in both connect to this brnch and watch our machines also connect to the airing so I'll be familiar with these three bridges so some of the comments that I have a you know basically issues are you interact with soap on reefs which I've showed up only eight risco to show another one is if you want to look at the flows so what is there's something called open flow to the the open this which implements I'm a righty pH proposal so the whole flow protocol is very important so the if you want to look at those flows you can use the only is quite cold oh don't flow me so if you're exactly coming on and I run or VSO vo5 color don't flow then I out rectify the particular bridge that I want so this is P re X so these are the flows what is called open flows you know in the particle a bridge channel you can recall DPR also 3d sonic flow you know in the PR tone or similarly traded to the countries for Libya and also put the study open closed or roof Shinoda dictate our traffic you know flows in open stop - oh that's for we are interacting if you just want to list the bridges that are live on your open this which you can do list PR so we see it gives me these three bridges so I have three bridges you know available on this all this which right now you can add bridge to a short break it under content like or vs vs Codel add rich oh lemme call it demo bridge demo BL so now if I do a misprint again you see I have one more bridge here to Anakin hard part you know to that bridge so Oh another one you can list the interfaces you know in particular of which will also list the interfaces in PR eh I'll do this example risk beat the all interfaces in VR so you see the bearings are more or interfaces like I should you know this is a QR q RS for the routing QG for the or or DHCP then the Nevada bridges other are ports as well so how to open it for baby our core muscles you know the baritone is only one interface so all manager should the manager the concept of manager in open with which the manager is basically like oh the controller you know controls the particular to pull the switch so this represents the address of the manager so if you you know get into advanced you know media on networking in the realm of open we switch you will know that also for Defined Networking you can have different managers you can have or there's something called open daylight open daylight ambien manager they are order several other managers that I can use to control the open V switch oh yes you can also this also a support for this basically they speak openly particular reach so if you want to run the command so what some of the most useful was the ones on that obviate this problem so and you can I think you can yourself you can use the help to get help you know about what you want to do so yeah you can do a lot of things actually like the scenes in movies which is like a something a plane on its own it as a lot of things that enhance the configurations that you can do here so basically that is what I want to show in these or demonstration so just to intimate you with what the owl openness which is used in OpenStack and also the three major bridges that will pro stock uses you should never forget the history major bridges they're everywhere if you need to troubleshoot OpenStack know they also start networking most likely you have to deal with this bridges and some basic commands in a lifetime used to interact with hopefully switch so on briefly I think that's what I want to show so let me know what you think in the comment section if you have a question or comment or audition or they'll beneficial to everybody so can drop it so or if you have something in mind I feel I should talk about winning no and I'll talk about it so thank you for watching our take a C's in some other videos bye [Music]
