Oh, hello everybody. Thank you so much for coming to this session. I'm really grateful to share just asked me when I'm with you. I love the technology. It's it's beautiful and elegant and it's truly an honor to share with you. I'm Howard Weiss. I'm a network architect at Citrix and my co-presenter today is Glenn Williams, and we're going to be talking about SD when I got into a restaurant about a year-and-a-half ago and kind of jumped right into it and I've learned a lot since then and I just wanted to maybe share with you some of the things that I wish I'd knew on day one,

you know that I know now to help Empower you to all use SP when so in this sector make sure here Okay, so we're going to run through really quickly out of the different types of Estevan offerings that we have so that you're all empowered to choose the right technology for the solution and then we'll talk about how to really scope an SD project and then we'll really jump into that. I think kind of the more fun stuff and I'll be understanding how the underlay and overlay networks interact with each other and particularly how LSD when does it's

over like magic and then finally we'll talk about some differentiators. What what makes us Citrix Espy win. So exceptional I would say Okay. So first topic we need to cover off is the different form-factors that you can get a solution in so that is the face of the bushel wine. So that's where we did a link application Winnie the Pooh pocket load balancing. I would do the result of a competitive swimmer. Stronger in this area of Truth. You put a pocket.

So that's the standard edition. That's what we used. We have 4 Premium Edition and I will come on side effects for discuss. Why don't flies Aisha. Sorry that is when you go to single link primarily between two Geographic distances to say the US soccer team have no license see why not. White noise into that and then to the Premium Edition. What we've done is we take the two solutions should we take standard edition and the wine optimization and we put them aside a single Appliance, okay. Now

first thing this is Clint covered in two different angles. It's covered from running a PLC stock quotations McCade. The worst thing to do is to walking with the products the customer expects the gas and something you guys and they get something else direct me to South 12th way. So we have a YouTube channel with a little bit of something to do with all features. We should go by the solutions team. We have white papers. I'm going out to other ways to facilitate you guys understanding what the public does. The main thing is calling someone's status. It's not comply with his thoughts

and just take some cables and put them in and it works out the box in each considered variables like you rooting fan of the scenario availability something. That's Michael. He's going to come home to sorry for the what we need to understand what we can be doing before we get to cite. Okay now with cold out here are the three different editions. This website has pictures of this. Okay. So when the main things here is the management on the configuration of these appliances to The Standard Edition

can be used with on you will try to put out the faceless cowpie solution which we have today, which is Jose multi-tenant very very powerful 2 extended edition with premium station on its own then you have to use the ATM which you may or may not seen for ATC product is used for the windup toys action. And if using wine off then using wccp web cache control particle. To get a couple of appliances here. I'm not going to drag you through every appliance that we've got. We have online data sheet that you can reference. The main reason for

this thing up here is just to ensure that if you picking the appliance before PSA or Productions appointment in sure you got the right put density and you say that you're delivering what you need to deliver. So the guy on the right side is a lucky shiny box with sits on the desktop. You can put a SIM card in front into him and LTE SIM card. So he works perfectly on the branch. The one on the left hand side the 5100. He's the big brother. If you want to reference the then you can find out a little bit more about the poor things to

say number for Action passing through which is supported on these appliances. Nikon push this home enough. Okay. Try not to make your life more complicated it needs to be. Okay. Why is good? Why dose my stations around in a world where buy we didn't have masters of fine with which is what we can deliver these days with a standard edition. So if you did want to go down the roots of wildflowers, I should get yourself a Premium Edition box use the wind component, which is the standard edition. It's a simple license key to turn up the heater. Part of the box. You can just turn it up

and bring it into flight. So I was certain boxes. So how do I know how much you know just a couple things to really start with Standard and then move on to win off that really applies with everything and I see when really take it step-by-step. Don't try to build out a whole bunch of sides and then push him out, you know. Especially if you're just starting filled out once I get it out and build out the next time get out of me really basic step-by-step kind of stuff will save you a lot of effort. Once you get really fouled up and you can get a little more Cavalier about it. But

that really is a good thing or not really doesn't fly to the baby. He said yeah, it is really important. Like one said it isn't plug-and-play but it sometimes does get presented as that and it is such a simple technology in some ways and a complicated technology Mother's Day it it's just I don't really know how to explain it but along those lines opening in the app earn-in understanding what it's going to take to get a sty on deployment up in a production environment as opposed to maybe a lab on your hypervisor is a lot different. So as we were saying, you know again

allowed to just reiterate this start with the standard edition. Stop first get all of that fixed. Make sure you're not you don't have a symmetrical routing things like that. And then you can go out back and turn on when off if you decide you need it like Glen said though that the advances that were making with fan with and Protocols are getting more and more intelligent, you know, maybe it went up maybe you won't find any of that. You've got to get the standard edition stuff set up first before you start playing around with went off. Gwen I guess you should take it from here

So this is an interesting when this comes back to what we said about it's not okay. You need to understand what's happening first on we use the underlined and over life is what you guys have today if you haven't got STD. Deployed which is using your traditional Legacy amp in a circuit so we can mow the TV internet circuits the overlay is when you take those links and you you almost create a logical pipe with them, right? So you got it together. So one thing

which we can pick out from here's the MP rescuing so you may have five or six mpls Q's in Moore. Okay, and we need to understand how to use those. We do typically try to advise or juice. That's a two or three MPS keys and let the appliance treats the MKS as a piece of wire instead of multiple strands of wire and p.m. To use this understand how we redistribute God will find a lot of networks with belt 10-15 years ago when they were certain Technologies available things have moved on the odor out of shoes, but why

change it works a week? Like that, but that's how we've come stock with me. New forwards. So take the opportunity to review your network settings while we're doing this. See nothing leaves nothing check everything this goes for every piece of the network. The ISP tells you they give you a hundred make link I can guarantee you going to be getting a lot less than what we typically do is Reformation 90% of the time it for me until we go and then we take it from there because the way the schedules out onto the why

we have tools and start the Appliance Department checks. We had a customer recently they have stuff to take you to the rice Pea in the end because they have packet loss guy on the line, but they didn't know that until they got a place together and it turns out that it was actually I speak nothing but leave nothing check everything. Hugo this is what you've been waiting for ya. So did you know I'm going back to the Glens last point about assuming and bleeding nothing and checking everything it has happened to me.

So often that, you know the cosmos say yeah RR wandling star are the speed and then we'll light up the Espy win and we'll get massive congestion almost all cases. If you see congestion on your link, it's because you don't have as much bandwidth as you think you have and I would also say that congestion is kind of the cardinal sin of St. Win-loss latency. We were fine with that we can deal with it but congestion we're really aggressive to Mark a link bad when it's congested and workflow to bring it back into play. So I would save all the things you absolutely need to avoid congestion

along those lines to it. Like I said, it's so common to see, you know, we'll light up a link the customer didn't know that they had almost half the time when they call the IRS be up in those. Hey, we're just seeing you know punzel awesomest link almost half the time to fix it in a cup. You know me some I call you just need to sell your interface to you know, NADA negotiate or something like that, but it is really critical though to validate that all before you go to prod with it. And if you do bring up SE when you're starting to see massive loss or congestion or something like

that. We're just the messenger here. Okay, we're not causing the loss or the ladies here. Whatever. We are. Just detecting it and tell him that the customer about it. That is absolutely true. So don't let anybody tell you otherwise, okay, the loss has always been there. It's just now we're finally aware of it. And you everything down to that know, I totally agree with you. All right. So, you know now clean kind of talk about write the underlined at work. That's that's your current routers in the mpls in your routing protocols and light and then ask me why I'm basically establishes an overlay

Network on top of that and then we'll talk a little bit about the way the underlay and overlay Network interact with each other. So let me walk over here. So basically here I've got this client. Okay, right and this client wants to talk to this server, right? So if you were to look at the the TCP header that this clients going to send you a it's Gateway Witching Hour cases probably asked me why and it may actually be this router. We'll talk about that in a minute or whatever. It's Gateway as we would see the header we would see the source would be the climate destination would be the

server. Okay. Now we get from this router this point though. This is where the overlay comes into effect ask me when is actually going to take and change the source and destination to its bits. Okay. So this client wants to talk to the server. Like I said, it's the Espy win. The other one's going to make a decision about which path it wants to send the traffic to that point though. It will change the address here to the source becomes ask me why I'm banned the destination becomes the other St. Wendy up on this side. So in this case would say this after you went into size to send this

packet nice a package because we do make choices that a packet. I pack a level which is really cool. But I'm so its uses this this mpls path. So now it's going to make this IP right here the source and this IP the destination comes along here. This is me when on here is going to get it reorder it put the original source and destination back in so that when this server C's the traffic it perceives it if you don't mind that kind of language for computer is it perceives it as you know, it just came straight from here probably one hop away with it would depend but probably one hop away and then

it's going to reply the same thing would happen with the thing. One of the many things at school about this is that this will never appear asymmetrical to This Server This Server is only going to see packets coming in with with this Source in this destination by Somerset one packet here in the next packet there. It will never be asymmetrical to me that that's just really beautiful. It's so simple and elegant and it's such a good idea. I don't know why we didn't do it. Long time ago the upshot of this is that you know, we are making decisions at up. Like I said some second level we

can pick the absolute best path. There's no way you're going to do that with a mirror router. You know, what if you're doing in bgp, when riding or something years since you're going to have a primary path and secondary path and if the primary past Dales after a while. We can birds in the secondary path comes up. This is just a light years ahead of that. But this concept is really important to understand any of this to me is the whole sdram standard magic right here. This is how we get from underlay to Overlay back to under lights and why it never seems asymmetrical to client

took me a long time to wrap my head around this. I'm not the sharpest tool in the shed frankly, but if anybody wants to talk about this at least for me, it was kind of hard to wrap my head around. I'll definitely around I love talking about the stuff to please. Please come up and talk to me. Alright, let's see here. Oh, I think I kind. Actually skip ahead of this. Well, there you go guys. That's the graphics and here it is all coming back so that basically again so the that kind of describes what I just said and I'm sorry. I was a really nice but I just messed up.

Another thing though. It is really important understand right that we do everything over UDP 4980. That's how I ball over that and so that means that your firewalls have to oh sorry guys, your firewalls have to allow UDP 4985 from every zip to every bit wherever that is. If you if you do not have a public IP on your SD. When is something else is doing it than it has to be a static one. The one that can't be a one-to-many mad or anything like that. If you just dropping the public IP on the table, so you don't have to worry

about it at the branch office. You can dynamically learn your IP is that's no problem because the they will spend traffic out to the AMC in the master control mode. That's how it will learn the eye peas, and it knows how to reply back. And I think there was one other really great. I think it's worth mentioning is right. It's not just the UDP. I'm glad we was saying Crypt on top of that cuz that's typically something concerned about security the empty out. A lot of people are

concerned understand about sending traffic just straight over the Internet to the other side. It is very secure because you know, we do encrypted with UDP 4980, but even beyond that we we will only accept sorry guys wrong button. We will only accept UDP 4980 traffic from other SV wehen bits and we know about that so we don't have somebody else to try to send us UTD 4980. They wouldn't and on top of all that you have to negotiate with the the proper private key. So there are a lot of security mechanisms in place to absolutely ensure that this

is a secure. Lucian and I can say that I have customers Banks Insurance customers medical customers in the lights doing SD win over the internet. In fact, lots of customers using only internet not getting rid of their mpls doing this and so far we pass all the Audits and stuff like that and I'm absolutely confident that it is secure and you can be to Sault Ste lamp straight over the Internet is a secure solution. When you want anything like this is kind of some big topics here. Okay. Alright, let's just move along

secure some kind of some things that took me a long time to learn with st win if you know this stuff or if it's really simple and conceptual. Thank you for humoring me but I didn't realize this for quite a while. Okay. So this is well documented. This is just on me, but I just want to emphasize a couple of things here. What I've got here is sorry guys. Thank you for your patience. What I have here is an SD when bridging traffic from this server to this likely mpls router right in

this case. We're not acting like a router with with layer 3 routing and her face is so if you look here on my configuration, I have two interfaces hear some this is like interface one and this is interface to they are in 1 G. And I'm reaching him. So that means any traffic comes in here goes straight down and vice versa and then down here is a proxy are going to talk about that in a minute. But the main thing about this that I think it's really cool. We're just a bump on the wire. There are the technology to do this, right? But if you look at the server here, it's Eyed Peas 192 168. 0.

100. It's Gateway is not one. That's not the SD Wham that's actually the same PLS router here. So This Server thinks again. If you don't mind that kind of terminology that is talking to this Gateway whenever it's trying to get anywhere out of its network, but actual what's happening here because I have my pee on that Network once we intercepted maybe we'll send it to that and plus router. Maybe we'll send it out some other internet router whatever we make that decision on a pack of pipe packet bases. Like I said, but this is how that whole ton of failed to wire technology. I'm sure you

guys have heard of that works, right the whole idea is if this St. When does go down we just become basically a really fancy patch. What that point in the next time this this server or this machine try to talk this router it actually is talking to the router. We're just a patch cable. But as long as we're up and running we are actually intercepting the traffic and maybe we'll send it out there and maybe we will one more thing that's super important here is frankly can't really think of a scenario where you would do this kind of a failed to wire Bridge setup and not proxy ARP on your

access interface so I can you think of a use case when you wouldn't want a proxy ARP trucks you off is very good. I mean this situation here is just the MCAT asked if you had an internet search as well. I knew Gateway failed, then you could proxy off of the SD. Was that the client can hit the Ice Cube and got season at us does the dad he could we use case so to 2 recap that right? So basically just imagine the center now, let's say we have four other way up here, right? Can just have one default gateway and nothing else. Okay, we got four other way only for

a little while. This guy wants to send traffic out if this router drop now it's not going to get an ARP request for anymore. And I won't even try to send it out anymore, which would be a real bummer because we have all these other Wyoming so we can use to get the traffic out there. And that's the whole point of this ask me where an appliance would start responding to our request for that router and then send traffic out other way and Link's so this machine here doesn't ever get to a point where things if you don't mind that kind of language is done. That's

it. So to my mind and there a lot of other experts in this room, so if anybody disagrees, I would love to know about it. I can't really think of a use case when if you are failed to wire bridging like this when you would not proxy ARP, it's really cool technology and its way to give you just really great availability. So again, we can talk about this in more. Tell afterwards I'd love to talk with you Glenn anything else? Okay. So here's another concept that I really want to talk about. This one. I kind of don't think it's really well documented. And this one took me a little while to wrap my

head around. So on this Appliance here. This is a really common use case. You're going to see when you doing asking when the planets with your man who got a couple of active layer 3 switches, right? And we want to drop an interface into him the person you might be thing is a porch and we'll just drop up or channel in the way we've done what we do at Newport channels on SD when they're not really that needed because of the way we fail over links and such but if you had just a single Appliance dropping in these act as switches, you're going to lose a lot of redundancy. So in this case

hear what we're doing is we got two interfaces in one group again, the differences were not Bridging the traffic here. So both of these interfaces are effectively going to share and If you will, so that is to say if some server here Arts out for the SD when I pee here whichever interface. Yes, he went picked it up on first it would just start using that interface. So it's kind of like a port Channel but it's really not know one thing some of you may be wondering about is spanning tree loop from the like and this we actually don't follow the RC for BPD used. We

will not past BPD use between these two interfaces so that we would never make a spanning tree Loop or anything like that. Basically just asking when is going to if it wants to talk to my pee in arms out, you know, both interfaces, whichever one picks up first, it just starts using that interfaced in actuality it when you set it up like this and I have done this many times and prod and works like a champ. What you find is that it just tends to stay on one interface all the time. So it's not exactly like that. We're not going to aggravate the bandwidth, but it's almost support Channel because

you do get the available. And that's what most of it's about one more thing about this you absolutely would not want to fail to wire in this scenario because if you fail to wire right that we shut down and now we're just a really fancy patch cable in that case since we're going to we're not we're just a patch cable BP to use would start going across the the interface and then you could get into some kind of loops and stuff like that. So when you're doing this that up here, so the ideas when you kind of think about it like you need a 4-channel we don't do that here is basically what

you can do instead of a 4-channel it will do almost everything in a 4-channel would do and this is the way you do it. You just pick your two interfaces put it in failed the block and then do not Bridge the interface like we did on the last one. Mr. Williams in comments on that, you know, that's really good. If we can is I would love to talk more about trust and distressing in this scenario here. I'm just imagine these are our land and our faces and I set them to trusted. But yeah, if they're on the side for sure they would be well probably entrusted. It really just depends.

I kind of actually like to set everything to untrusted unless there's a compelling reason not to not to like you need to view Dynamic routing or you are lots of reasons. But otherwise, I would say, you know when in doubt set it to untrusted if we get some time at the end we should really dive into that because there's a lot to it. It's actually really interesting topic to Virtual inline. Okay. So this is a virtual inline set up here, right? So you can see here. We've got to a computer and it wants to get over here to some other computer. So

does appear goes over here to this this device and then we make a decision sent right back and it's going to go out either the internet or what, you know that until I see pending on what decision was made. This is almost always done with sea bass routing and you can see here basically a tropical hairpin on this as he went in her face is really common set up its really, with PLC is this is all we have two sons of dakshina almost saying this is how you do a PLC set it up virtual online doing policy-based routing. I actually really prefer to do it with Dynamic routing. I

mean just for maybe a little piece of the PBR spine, but if you're once you try to migrate to a really big environment that the pr can get pretty rough and I actually really like to do it with that ebgp over everything else. Because ebgp will just be preferred over every other routing protocol solterra eigrp shop or something like that if we just set up TV GP here. So this isn't it just start sending traffic to us just like that there a couple other things about it, but the main takeaway, is it the reason I'm really mentioning this though is I want to talk about is

this this hairpin issue here? Okay, it's just kind of I've always thought so too bad moms way and this actually gets me to the next point about how beautiful and flexible SD. When is the way you can if you're wondering, you know, can I cabled up like this or do that, you know put the skill hear the answer is probably yes. It is. So flexible that you can you know, it's almost a little disconcerting how nebulous it is. But once you wrap your head around it, it's really quite beautiful soul in this scenario here. Our issue is that when we hairpin traffic like this, we really only getting

happy available bandwidth, and so you would need to make sure that this interface Can support twice the amount of license bandwidth you have if you really want to take full advantage of USB when one way to work around that would be to actually cures kind of the same thing. So here's a virtual inline deployment. I guess it's the exact same thing. The only differences instead of just having one interface going back in. I almost no arbitrarily to find this interface is the Lan interface and I'm telling you a few am just send it out another interface to the switch so I can do the same exact

thing by just cabling up another interface. And now the traffic is actually flowing in line through us. The only here pay here is on this this switch to buy switch there really well suited to do anyway and this this is definitely a good way to work around you want to do that kind of get off to the side of the the stuff. Do you want to just get in line and disruptive especially for like a PLC or something like that? This is one really easy way to do that and to avoid that hairpin issues and I've done this a lot of times too and I can tell you absolutely it were Like a champ any any kind of

switch switches are really well suited for this kind of thing. So this was a really common deployment that I use for PLC kind of stuff or any of my production merch one line deployments to Williams comments on that. This is actually are recommended. I personally try to avoid PBR because it is quite happy intensive on the CPU on Brutus Riot would have calculations and everything about David. Or we might go to another thing and he mention is going to get preference bgp, right which means with the costing

if it fails then you run the light Network again will take over because you have a preferred route. So this is what we recommend for graceful way of bringing the appliances in to network. You can choose something that's just a rough to our clients and send the rest out to the internet on the underlights. This is she is beautiful example changed appointment methodology is either at The Chew today to send to a mixed match how you wish but yeah two examples that is

one thing that is so neat about Espy winners. Just so flexible. Like I said, you can do it in so many different ways and we are still finding kind of new ways to do things. So, Different to you know, try that Sababa sleep don't play around your customers brought too much. But like I said if you can conceptualize it there's a really good chance it's going to work. It is a really flexible. The ViaSat is just really sucks. Okay. So I think this is really important. This is a really good way to get past the interface without having to disruptively get in line on a deployment because I can be kind

of scary to plug it in line on your customers Pradhan cross your fingers that all works. Although it. Does I can assure you. Okay, and now let's see here. This is going to be some important stuff about kind of how the overlay network works now in this scenario here. We have a PBR since we are in line in this case and we can if you look we can probably figure out why we can't tell if it how if we're getting a bridge not but the key thing here to know is that this router has in his case of PDR. On it, right? So when we send traffic Source from the. To VIP, that

means we expect this router to know if it's sources. To the next stop is going to be this guy up here then peel spider resource from the. 3 bit. Then we expect this router to know the next top is going to be this guy in this case the internet that's really the whole thing. Right? So the way we we do our thing is whenever we choose a wound like we always sore sit from a VIP everywhere and Link has its own bet. They can't they can't share business. That's that's that's our whole thing. So we Source from the bit that we want to use. And in this case we're relying on this router to make sure it

understands if you absolutely have to send the traffic that way and the same goes here. It is all a layer 3 Technologies, right? We don't do any kind of I mean at the at the Espy when SC level we are really just a super awesome intelligent router. How do you know when off on the other hand is all Are too and transparent to like but mostly that's that's the case here. This stuff is so important. I don't know what it is, but it's really common to see when you when you came up to see me Goshi ation issues and stuff like that and more so than I think with other things I

don't I don't know what it is. But you absolutely need to make sure do yourself a favor right away after you get your asking when up go check the interfaces out and make sure that everything negotiated correctly if not needless to say, but I will anyway you're going to have some issues. On the traceroute to Liz is very nice on SD. When so what it does it actually Trace routes from zip to VIP. So if you're trying to get a virtual path up, it actually will show you the path into work. It's dropping. So it's really critical if you having trouble getting an STI have to come up to actually do

that the trace routes on the sun to make sure that they are indeed that the underlying network is getting you where you think you need to go. Glad I'm just going to move along there and think are all right and okay on this one. I'm actually going to skip this but basically are a lot of it but at a high-level, I mean we are if you look here on the land win in the window and you can see the different things we do in the Rehab Services sites rules classes and flows. I would like to talk about this more but I think it's going to get us a little off topic giving our time. So if you don't think

that's another two hours exactly. Yeah. This is a really great topic but I think we're going to have to press forward here to this one. OK Google with the land of something's not working. Like I should you can always just set everything to pass through. So essentially that cement won't process it anymore and it should just be going straight through underlay if they'll tell you you know, where the problem is is asking where the problem or is it the underlay environment the problem Anything else you want out of that clean. This is also very good mythical to G4 when you're introducing

sty an issue Network back to the beach with my mode. If you were using an inline mode instead of sending me off, virtue past and doing any sort of like two techniques. We've sd1 that you put into the Ava light to pass through mode. There be a screenshot a moment. What it would do is it would take the pockets and put it through the underlights essentially the St. Weiser a router at that point don't do me any type of magic again. And I think this is yeah, I think yeah, we do have a lot of great onboard diagnostic tools. I will

say this, you know, like if you light it up the past don't come up first check our make sure you have ARP that you're talking to your gateways after that. Go ahead and run the traceroute see if your gateways are getting you to the remote bits packet captures are really useful. So pick your interface to a capture on a test to see what the end of the other ask you. When is not give me the traffic go to the packet capture see what you're saying there with the with that stuff. I mean when it doesn't have a command line to do a lot of the Diagnostics, but the gooey does give you all the

tools you need to diagnose just about any kind of connectivity issues that you have. I think it's fair to say the only thing I ever had someone that is proving out beyond that to you maybe a customer that than that is messed up or the PBR is messed up or something like that, but Set the tools are all there for all the trouble shooting. So that's in system Diagnostics. They're all there. So if you are having trouble go through those tools and you will have the tools that you need to get the lynx up or at least determine why they won't come up just a point on this another

case selling point for SD. Wan is typically with you. If I was to die in route as you have to look into each individual device, so don't know if management you've got to do with this single management Potosi, and figure out if your home network you push it out with you castrate a mentioned earlier instead of having Sky to each individual Appliance run traceroute paying packet capture Diagnostics with the orchestrator, you can go into the office, right and you can push commands down to the appliances just like a single-pane-of-glass. I know the pain

I've had in the past before Citrix of where I can move individual notes and you could a whole spreadsheet at this IP Finn's Management in this login. So does simplify your home network employment and management process? Thank you. Okay, I think I'm just going to push the song as we're kind of getting to the in here. So sorry and I'm just such a talker. I think I'm going to get past this one to do. This is really good stuff. I think it's just to ensure I mean GMC Yukon change. This is a way of protecting the end to you in

the past is always 1500 with me on this is very powerful for effusion. No t-link stuff like that. Yeah microwave links. And I think I'm going to skip that although it's so good because I really want to get to talk about some questions and stuff. You guys. He was a really good one that would you need to talk about this one thing that a lot of old-school kind of rotten people have trouble is letting go of the control right there. Like well, I've got all these dscp Q's carved out. This is for my boys in this is for printing and you know, we use this link for

that and this thing for that I miss my acting like this is my primary link that will make those decisions way better than you can just manually do it. I'm like I said, we are making those as sub 2nd level. So try to let go of all that and let the sun manage that for you don't think about which link should be use for boys and which one should be used for printing let the judge decide all that for you. It is going to decide way better than we can or just a mere router can that applies with with all this kind of stuff? So there's no active and back up links anymore or preferred links for certain

types of traffic anymore. That's the win. Okay, it is just automatically taken care of all that. And I want to get to so much other stuff here, but I really want to get to this because let me just give her a couple of shout-outs hear about some stuff that I think is really going to be good. I think these two on classes tomorrow all going to be really great. But really I want to talk about this class. I absolutely recommend if you guys want to learn more about asking when is is check out this one right here because this is going to be from Matt Brooks and Jesse

Wilson map books has a really smart guy who actually taught me ABC and Jesse Wilson is our education architect who designs all of our educational material self lot of stuff. I've learned basically what companies do guys when they're going to be diving right into this kind of stuff and how they're going to use SD when to optimize workspace connection and I will also tell you this Matt Brooks is a real wizard with 200. That's what you guys want to talk to him about dscp q's and get his take on it. He has some really great perspective on you know, how to manage dscp with SD win in

the lights. So do yourselves a favor? These are all great section 2 Monopoly do yourself a favor and be sure to catch this session here. If you want to see kind of SD when you know get get down and actually deliver some work space connections for me. However, I'm afraid it's 1196 e 2nd from Bob we can go to law say about sty on we talked about how great it is for deployment that you may not be ready to do this yourself the simple reason and I hear this a lot of times is weed a manager NPS reaches today, right? We don't manage our Wild Side do we really want to go

down this path of having to measure Spanish this technology getting involved with an MSP service provider. Does this fool you is an interesting topic to look at right know everybody's comfortable getting into the weights with with this word technology. Sorry for me. It's is 119. I'll see you all there. And I think with that we ran a little long but we can definitely have questions and stuff like that and we can also talk after the fact so questions comments anybody. Okay. Well then I'm going to just keep on talking here. I just love to hear

myself talk. I want to say one more thing. You know when I first started doing LSD when Everybody's Talkin about replacing PLS with internet and I was thinking you can't because there's no POS on internet you you can't do it. I have to say though. I'm your can't make promises, you know, every environment different. I have multiple customers who have completely dumped their mpls and they are just running on cheap Internet only and their boys stuff like that works like a champ. So even though there is no qos on the internet links you get the estimate in a couple of pretty decent internet

links and we can give you a pretty qose kind of experience. So it really does seem like I said, I have multiple customers were completely off of mpls now running just on internet much cheaper all with that steel. And so it really does work. We have lots of mucus at the back that up that check every month. Thing as well. I guess we could have an open the chat right by the wayside just a bit of Shameless promotion that one computer circuit to turn it upright

and then once he saw all your thoughts she sends the site we say to the guy who's on Sligh who may not be technically shot that you say you put the green wire in here in the red wire in here in the blue wire in here and then you zero-touch Vision stanza mean he looks at me since it's real simple. Lesson get Opium Den tonight is the big something. We haven't carried over yet. But yet with the internet we will use without shutting and ladies waving at me over there. So yeah British action, which we've got inside the appliance. We can

almost create you and Phyllis cage to almost we do something to have Labs coming out to look at the lab. We can talk about the ioc's if it's something you're interested in, you know run you through them in this video is on YouTube. If you search for 651 the pretty obvious a lot of videos recorded which will show you the sort of technology in practice. So the resiliency those videos are legit. That's that is had those videos. That's how it works. Go check those videos out and they're pretty awesome. I mean the Office 365

faces covered. Well, thank you so much for coming and letting us share sdram with you do yourself a favor and check out at Sea when I absolutely know you won't regret it. Thank you everybody. Thanks for tending.
