Cisco CML External Connectivity | Cisco CCNA 200-301

you [Music] don't get out what you put in all in the you've lost everything and welcome everybody to the Keith Barker channel here on YouTube it is great to have you if you are just joining us welcome my name is Keith Barker I'm a CC CIA I've got my first C CIA Cisco certified in a network expert back in 2001 I've got another one in 2003 and I've loved Cisco technologies ever since the objectives for this channel and for this video are pretty simple I want to provide you with the best tools and tips today that you can use towards getting your CCNA and part of that involves building and hands-on practice I had a Kahoot session a quiz session on Sunday I had those Sundays at 11 a.m. every Sunday and one of the questions I asked was what is one of the most vital aspects to really mastering and learning this technology and the major answer was hands-on hands-on practice I totally agree I totally agree now as far as a tip or a technique how can we get that hands-on and there's three basic ways of doing it one is you can buy the physical gear nothing wrong with that we can buy the physical gear like used on eBay and such and put it all together it is a lot of fun in fact we're back here well this is my my cue card for today take one take one and done that's what we're gonna do so anything that comes up in the video the cameras rolling so I I recently bought some gear and I bought some like little 35 sixties that are have no fans so therefore they're more quiet for the office and so forth and some wireless LAN controllers an IP Phone and such and I've had a lot of fun with them and that certainly is an option Oh Bing solid-state hopefully it'll be okay back in the day like a decade ago two decades that was the only option is that physical gear but now we have other options such as virtualized options so if you want to get a free copy of packet tracer or netacad comm just go to netacad comm cisco site sign up for a free account get it for free tons and tons of packet tracer labs in fact let me show you share screen with you real quick and they bring this up all right hi oh so one of the labs we did we connected a home lab that you could do by purchasing gear to the Internet so here's the Internet here's my cable / DSL router whatever we have from using my home router and my home network and then I recommend not putting all your gear directly on your home network as far as all connected that same network because you know I discovered is that there's a lot of people probably at your house that absolutely don't want interruptions to service so one idea is to go ahead and put the edge of your home network your home lab that connects to your home network and then have everything else isolated so you can have spanning tree just go berserk and all these other kinds of things and it won't harm your home network because it's considered to be a production network so we we have that video on that and if I bring up this real quick just want to remind myself what that video was here this yeah it was called connect your home Cisco lab to the Internet and you can find that on my youtube channel so Wow eight point four million views that's good and one hundred four thousand subscribers I love it when we can make a difference give you the best tips and tools for you know getting your CCNA so I appreciate you participating and watching if you find any value in this please give it a thumbs up and and so this is that video and then I had people say well I don't have all the gear and I want to practice I want to practice DHCP and NAT and VLANs and static routes and OSPF and so forth but how do I do it without a real home lab and the answer is I thought that uh this video right here packet tracer home lab to Internet simulation so you can watch this video and the links for the description there are in the description there's links that you can download this lab and walk through it so whether you're doing physical gear or whether using virtualized gear the big key is that you want to make sure that you're you're practicing hands-on when you're learning something practice practice practice alright and since they've got it right there we can also have a little fun like this make that mustache a little darker give myself a little more beard all right so what I want to do in this video is I like to share with you how we can do that same lab again but this time using Cisco modeling labs with the personal Edition which is it's a commercial product have to buy it it's like 200 bucks a year but it's fantastic so if you want to use that instead of packet tracer I just wanted to give you a demonstration of a tip of how to get a Cisco modeling lab network connected to your real network including the internet imagine having your lab and being able to from your Cisco modeling lab or packet tracer lab well can't do it package me sir but your Cisco modeling lab did it get full connectivity out to the Internet so only use the same topology as we had before and we bring that up is right here and let's just do this but this time we'll do it in CML Cisco modeling labs and if you want for tips on installing the basics of Cisco modeling up I got to give a huge shout out to David bumble he has a great video on how to from downloading installing and setting up Cisco modeling labs the personal Edition it's fantastic so I didn't tell David I was gonna give him a shout out but it's a great video you should go check it out subscribe to his channel and he's got a lot of great content I trust David bumble he is very thorough more meticulous I love it so um I've got Cisco momming labs already set up I would like to share with you a couple details that will help you if you are using Cisco mobbing labs and it would look like something like this I will do is will so here we have the home network that's physical and then we'll add our let me change my color there so we can see it let's add our one in Cisco modeling labs so everything from here over will the Cisco mobbing labs and we'll bring our one hour switch we'll connect them together and look through the configuration and then I'll walk you through how we can take this network this Cisco modeling lab and connected I wanna say physically hey connect it to the home home network and have the same functionality so this router and this switch and all the other devices here can get access to the Internet it is so fun I love it I also love this I love the fact that CCNA is a stepping stone and I love it when people jump in they focus on the technology they learn it they practice it because you can use those skills that we're learning in CCNA and you can apply those as you continue to grow your career and get into the world of IT even further so I've always I don't my whole life I feel like I've been an underdog I still do I still do I feel like wow people you know think faster than I do it's true especially as I'm a little older now so I have more wisdom but I don't think is fast and I remember saying keith's are talking pretty fast money so but reality is that I've always felt like a position of underdog and CCNA for you can be a great stepping stone to greater things that beyond so get the foundations down and no matter where you're coming from you've got internet access and you can get packet tracer for free you can watch my packet tracer labs so you can do the hands-on practice you can learn the technology you can master the technology and then go on to additional things cloud computing in CCP level topics security cyber security pen testing whatever else do you want to do but this is a really important stepping stone and from my heart I've always felt like I want to help you know millions of people come from a point where they don't know this technology where they do know it and then they can use that as a stepping stone as they go to bigger things I feel I feel really important about making that difference so thanks for watching this video let's take a look at Cisco modeling labs and how we can connect our home Cisco modeling lab network to the live internet and I'll walk you through the steps so let's start off with a couple important pieces and that would include this I'm currently using VMware workstation you can also do this with VMware Player and any way you want to do is find and what I did was like I just follow the instructions on installing Cisco modeling lab but one of the things that I want to do is I want to share with you behind the scenes what I'm doing for networking and here in VMware Workstation you click on edit and then click on virtual network editor up here on the top left and then you click on change settings right here and that lets you modify just give me a problem for authorization for that so it didn't bring up that window so I'm gonna go back oh maybe did it sit there we go it was just hidden so now that I can edit it here's one thing I would encourage you to do is VM NetZero by default is going to bridge meaning like a layer to switch there's a logical layer - connection between VMware Workstation and your actual physical network but but check this out if you have lots of networks like lots of network adapters in your computer but which one is it gonna choose hopefully it'll choose the right one I think to avoid problems you want a hard code that so I'm clicking VM NetZero which by default is bridged to your network card your Ethernet card or your wireless depending on which one you're using and instead of saying Auto like a lot of matically figure out which card to use I went I specified my actual interface I have a that model of network interface card but I said bridge to that physicist and that way there's no guessing game that VM net zero is absolutely tied to this card and that's gonna remove a whole bunch of frustration if you have multiple network interface cards all right so that's what I've done I'm going to go ahead and click I did not make any changes so I'll leave that alone and I also followed one other thing for the virtual machine I went to settings during the initial installation of it and for a network adapter I didn't say just bridge which is the default bridge to the physical network I said custom use VM NetZero because I like tight networking I like networking that doesn't have a bunch of variables in it so the network adapter for this virtual machine running Cisco modeling labs is linked to VM net zero which is hard-coded to my real Ethernet network card so everything is nice and clean all right it's like therapy getting it off my chest all right so I booted up it gave me this IP address 192 168 1 2 0 3 4 managing it and I'm going to bring up a browser and let's just open that up so I just went it right there 192 168 1 203 that's great that's the IP address if you go with HTTP it'll redirect you to HTTPS so you can go either way you want and that's where I'm at and let me bring this up full screen with I'm gonna use eleven all right so to create a new lab and what we're gonna just build that same lab we did in those previous two videos packet tracer and physical gear but we'll do it here in the Cisco modeling lab I'll give you step by step instructions we've got nothing on the screen no labs I'm gonna use will build the lab from scratch so let's go ahead and do it let me get my face my face is fine alright so I'm gonna click on add lab up here and here's the new lab I'm adding at so the time zone isn't my local time zone I can leave that we'll call this home lab to Internet right and then we'll click on it and that brings it up so I've got this fresh you know green field Network design that just are nothing here I can start playing with so let's go ahead and bring over a router over on the right I'm gonna grab a OSB that's just an iOS a virtualized eyelash router and also going to make it bigger open the top left I'm gonna click on zoom in a few times many times and also I'm gonna click on this little icon right here which is center view and that way I was just kind of centers it for us one of us actually I'm gonna drag it over and once I have a few devices on my topology I'll use that Center view again alright let's go ahead and I'm gonna double click on that and rename it and let's call this router one because that's what it is alright and for the details for like the step by step and you know how does iOS work and check out my other videos in this playlist or whatever using for your main course of study my goal here is to show you how to do Cisco modeling labs connect it to your physical network and verify it's working let's bring out a switch I'm gonna grab the Cisco IOS lvl2 this is a virtual layer to switch and I think in the previous videos we call that switch 1 and we may need to look back at the at the topology just to verify that that is what we called it and all the interfaces so there it is and let's connect them together the way you connect them together as you hover and then you this icon for a link just click and hold and then drag over to the other device and then it specifies ok what ports do you want and I'm going to use gig 0 / 1 0 / 1 because that's what we used inside the other two previous videos and you can verify that by clicking on MMC here where is that at it's not running yet I was hoping it's gonna show us the the connections all right so if I could click on one of these devices list while the labs not running and I click on connectivity it's gonna show me where we're connected from dese which ones perspective all right so we've got switch one router one and let's also while I'm here let's bring up the external connector this external connector is how we connect to the external network and I'm gonna go ahead and click on that a couple times and go to note info and I'm gonna call it home real Network which is the 192 168 1 that work in my case and I've got my little home default gateway at 192 168 1.1 great now before we leave that device I'm also going to add some connectivity so I'll go ahead and click on the link icon and drag over at r1 and to be consistent with our with our diagrams from earlier let's go to gigs 0 0 and we can click on that real home network and I want the connectivity hmm click on r1 all right I need to practice a little more once this is running huh oh I'm no longer I'm no longer selected on the router okay I'm not gonna spend too much time once it's running we can look at each these devices and it'll show us all the connectivity involved hmm all right little frustrating I'm okay with that it's totally me that's totally my fault so there's our one connectivity all right this is so I just going too fast so click on the device click on connectivity it'll show you the port's involved and I must have clicked away which is why it didn't show me that for these two the devices all right so we've got connectivity gig 0/1 on switch 1 2 R 1 and gig 0 0 going to my home network now before I actually start this up I'm clicking the home network this is important if you want this to work the way that I intend it to work which is bridging out to the physical network by clicking on the home real network there and going to edit config we want to configure it as an interface type of bridge before we power it on because if you power it on then it's gonna complain it's running you gotta bring it down wipe it and start over so the real home network I'm sitting up in bridge and you know while we're at it because we're here that's also bring out a server so there's an Alpine Linux box so I'll go ahead and change the name on that about Linux and let's connect him to a port so I'll click on the Linux box and click on a link and let's put him on so a lot of ports go ahead and use Ethernet zero on the Linux box and let's go to [Music] Giggsy road two on this switch great okay so our basic connectivity is in place let's power these things up there are some options for pre loading a whole bunch of configs I'm gonna take it from the ground up just from scratch so I'll click away I'm not selecting any of these specific devices go to simulate and I'm gonna click on start lab there's a little icon next to each one of them indicating that they are powering up but they may take a few moments for that to happen perfectly fine well that's coming up let me bring up my notepad document with a lot of my favorite commands so I will copy those these apply two switches they don't there's a few commands for routers that that there's a few switch related commands that won't apply to a router I'm just gonna leave man I'll take the errors for those things like VTP domain the router says I don't know that is or spanning-tree mode I don't know that is I'm just gonna paste these in on all the devices all right so I'm gonna right-click copy that and if we now that it's running if we click on the switch and go to console right here this little console icon and I will bring this up a little bit all right and on the console tab here I'll click open console and it's still initializing which is fine over here on the right and their columns are gonna click on auto and that'll give me more width fantastic that's booting up the Linux box let's go ahead and go to a console for that all right and I know login as admin no root and hopefully at Cisco okay we're in and I'm off the screen my taskbar tasks are settings and let's go ahead and tell it to automatically hide all right great that'll give us the so we can see the bottom there on the bottom left and let's do a I peek ifconfig right it has no ipv4 address because we didn't we don't have a DHCP server we haven't configured that yet no worries we'll come back to him in just a moment so on switch one let's bring out my notepad document here you won oh it's hidden great I said my tasks right like where's my taskbar all right we'll grab that and take it and we'll just go to switch one to the console and make sure we're in the right starting point all right go into privilege mode and just gonna right-click and paste and boom we're good to go so this which is I'll call it switch one real quick right fantastic go to our one and we'll go to the console I'll say no initial script and then was paste in that command as well pasting the config all right Wow it's this live iOS and great fantastic all right mister while you're cooking on that let's go ahead and bring out a pen let me talk about our plan so here's what I intend to do this is the 192 168 got one network and we're gonna do dot eleven here a default gateway going to dot one which is my home router and here we'll have this port will be VLAN 1 mmm yeah B then one and we'll make interface vlan1 and we'll give the IP address of one to be 2.16 dot one dot 200 and we'll give this guy the IP address of dot 11 on the 132 16 one network that way I'll be consistent with the previous two demos and we'll set up Oh s PF between these two will tell r1 there's a default route going to the real internet with dot one is the next hop and let's put this port right here which is going after the Linux boxes put in VLAN 10 and let's use the address of one semi 2.16 10.0 here that means we'll also create a virtual interface on the switch for VLAN 10 and let's give it dot 200 there how much time do we have let's also set up a DHCP server on this multi-layer switch so that it can hand out an IP address to this Linux box and we'll also need to do NAT here on r1 if we want this private network of 1 to 2 16 dot 10 or once to 2 16.1 as traffic goes out be translated to this local network so my home router knows how to get back to them so we'll set up NAT here as well and then my home router that goes up to the internet is also doing a little bit of path more details on all those nitty gritties in the previous two videos on connecting your home network to the internet and also connecting at the packet tracer lab to the pseudo Internet all right so that's our plan and back to the router we go bring up notepad again and I'm going to copy that in a privileged mode paste this in it'll bark at the commands reddit of switching that's fine with me and it's gonna be called r1 and we'll do a I'm gonna save it as we go all right let's point let's configure the interface this gig zero zero is here on the on the right so we'll do it already in configuration mode interface gig zero slash zero no shutdown IP address one ninety two dot one sixty eight dot one dot eleven with a three octet mask that looks fantastic let's do I do ping do one ninety two dot one sixty eight dot one dot one I just want to verify that I can ping my default gateway and the crowd goes mild at least I did great that is this router r1 pinging my default gateway on my home network fantastic let's also set up a static route a default route IP route and what is the syntax for a default route mmm what is that do you recall if you're thinking I had a whole bunch of zeros in it you'd be spot on it squad zeros followed by quad zeroes and then the next hop which is going to be one ninety two dot one sixty eight dot one that one and we'll do a do show IP route just to make sure we have that static route okay there it is right there fantastic so we should be able to our one should be able to ping the internet if we do a do ping I'm doing the do because the main configuration mode do ping of 8.8 today today almost too good to be true let's do a let's do it again and let's do a trace this time let's do a trace 2 8 8 8 8 and that is going out to that's going out to a Google DNS server through the internet so the first hop is my default gateway right there and then my default gateway is using a next hop through my service provider are there and I and so my little home router is doing Pat and we're doing network address translation again somewhere in the service provider network and then we're going out to the live internet with the IP address of 100 as another path router in the path great alright we are halfway home I'm gonna go ahead and click on the center option here I guess it's centered enough if you want to move them all around you just click somewhere in the free space and just drag and you can put anywhere you want all right so r1 has a default route let's configure OSPF you support the 1 sin 2 to 16 anything so to do that we'll do a router OSPF spelled correctly router OSPF one network 172 dot 16 got anything with a wildcard mask that says that and we'll put that in area zero it's always a good idea to verify as we go so I'll verify that our interface gig zero zero is participating also I want to source a default route will do a default information originated I'm gonna say always in case I lose my default route I can still advertise the default route and then also while we're here on our one we're going to need NAT so we're gonna need NAT because my little home router has no idea about how to reach the 172 network going this direction so I'm gonna make everything up here on our one this would be the outside this be the inside I'm a giving to this home router appears it's coming from this IP address let's do a I Pat port address translation with an overload on the outbound interface this is great practice whether you're doing it with physical gear whether you're doing a packet tracer whether you're doing it here with Cisco mobbing labs it's all great practice so let's go into interface gig 0/0 IP net outside Oh Oh this is like live gear look at that tres tres tres packs are not good not a good sign so let me go ahead and issue that command again IP now that outside I just abbreviated the out and interface gig Wow 0/1 IP net inside so the traceback yeah not good but it looks like said cpu hog something about so if it doesn't work we'll go back and revisit it live gear can sometimes do that too as well all right trace backs are a real thing and they're never good alright so let's do a do show IP not statistics and so I've got my interfaces confirming where I'm at let's create an access control list they'll specify who can be translated so we have a couple options we could do a named access list we could do a numbered access list either way it can be a standard access list that's going to be used not for filtering but for simply identifying as part of Matt who should we translate and who should we not translate so let's do IP access list standard we'll go ahead and call it for that how about that well permit anything that begins with one city to 16 so the wildcard bits would say we care about matching the first octet we care about matching the second octet and we don't care about these third or the fourth octet and there's our X let's do show access list it's always important to verify as you go because one little problem that you missed earlier on it's gonna mess up the results later so I like to verify as I go good tip regarding practicing getting things right to show excess list and when you're in the configuration mode and using the do command there's not a lot of context-sensitive help so it also helped confirm that you understand what the commands are even without contents that context-sensitive help okay there's our X's control is fantastic still - at IP nat inside source list we're called it for not and spell that exactly correct case sensitivity is important or net and then we'll say we're going to overload on the interface and it's going to be gig 0/0 that's the outside interface space overload so that's our net rule it's in place and we should be good to go we can test that here in just a moment so let's go back to switch one and let's configure switch one so I'll click on switch one and click on console the ticks is the console for switch one and the party begins show interface status not a bad place to start alright so all the four ports on the switch are in VLAN 1 by default they're not routed ports so that means the connectivity from r1 to the switch our ones connected to an access port that's in VLAN 1 as an access port I'm gonna hard code that though just so it there's just just for fun interface gig 0 / 1 switch port mode access because this gives you a practice for the CCNA commands once again and switch port access or VLAN 1 hard coded now as this access port and do show VLAN free survey says great they're all in VLAN 1 now let's configure an interface VLAN 1 and if you know the difference between VLAN 1 and interface VLAN 1 that's great if you're thinking I don't know what the difference is check out the videos on multi-layer switches in the master playlist and also switched virtual interfaces and how they work so switched virtual interface an interface VLAN is a layer 3 logical interface that lives in the corresponding VLAN so we'll do it interface VLAN 1 which I just did I guess I didn't interface vlan1 so now we're in interface configuration mode real n14 interface vlan1 an IP address is going to 170 2.16 dot o is it one dot 200 and what I would encourage you and almost gonna do a no shutdown I see there's a shutdown message there so I would encourage you to practice practice if you have a home lab using the video regarding home lab to the Internet if you don't have a home lab use packet tracer bright eye that lab is provided for you in the downloads go ahead and practice it or if you have Cisco modeling labs you can use this method here the key is practice and the commands and the logic is the same as far as configuring the devices let's do a ping to 170 2.16 dot-111 that's the IP address on our one or should be I'm glad we tested all right let's troubleshoot why can't we ping switch fun to our line I was probably as probably just me let's hear back on our one show IP interface brief oh yeah look at that so right here on this interface on router one although it's in my diagram it's not configured so somebody once said it's important to have the configuration on the gear if you want to behave the way you expect it to so let's fix that config T interface gig 0/1 no shutdown that's important too and then IP address is once a neat reconnect console IP address is 172 dot 16.1 11 oh my gosh my mouse got out of there so IP address 170 2.16 dot one dot 11 I'll say it with a happier face and the mask is a three octet mask and it is already up but I just forced to have it there and let's do a ping you 170 2.16 dot one dot 200 all right now spanning-tree if it was running and that port had just come up for the first time it could take a moment for that but we have connectivity on between switch 1 and r1 let's do a show IP ospf interface brief show IP ospf interface proof because I'm no longer in configuration mode oh come on now all right so it's it's considering life in a few moments there should be a neighbor ship we'll go back to switch one verify OSPF is enabled there as well oh it's not great so router OSPF one network I'm going to bring in all the networks here because we're behind we're in our internal lab networks and I'm gonna say bring everything in and put them into area zero and if this comes up right away so if if there was a dr already set up which are one finished its wait state and became the dr if it's already in place and a new router comes on it's the second device it'll form an adjacency right away if you're bringing two up at the same time and they have to think about who's the dr or BDR and how that election and go through the wait cycle it might take 30 to 40 seconds ish for them to actually bring up a neighbor ship but if you already have a dr present the other one comes up should be very very quick okay and that's the kind of experience you get with lobbing it up and practicing whether it's packet tracer whether it's live gear or whether it's here on CML alright so let's do a show IP ospf neighbor won't you please won't you be my neighbor show IP route this will verify the IP routing okay yeah it's still enabled and also we have a default route that we learned from our one so okay let's let's just check our work here the play-by-play goes something like this we've got a default static route going 2.1 we've gotten at here to the inside the outside we have an at rule it says anybody coming from a source of rest of 132 anything can be translated we have OSPF adjacency between switch 1 and r 1 it's a full adjacency in it two-way x start exchanged loading and foley did that whole process switch 1 has a default route pointing to r1 it's great and let's verify that switch 1 can actually make it to Google that'll verify all the pieces they're working and it's a great exercise so whether you do this with Cisco mobbing labs or physical gear or the free packet tracer lab I would encourage you to practice this all right let's let's get a shot ping 8888 traceroute a date a date sure enough look at that oh my gosh I still get a big kick out of when lab environments like if her practice environment and connect to physical and live gear and everything works it is amazing and in the real world yeah half our gear especially servers is virtualized you know virtual servers and a lot of our networking gear is virtualized up in the cloud but the concepts are the same all right let's go back okay so we're almost done we've got our connectivity to the unit let's bring up a client and make sure it can do it too now for this client to work what I suggest is let's make a DHCP pool on switch one and have it hand out the IP address I pin this up so we this is for my benefit so let's use for this port and I'll to verify where that's connected I think it's 0/3 but will verify that let's configure that to be in VLAN 10 so an access port in VLAN 10 let's also configure interface VLAN 10 and let's use 172 dot 1610 and let's give the interface VLAN 10 the IP address of 200 on that network and then we can in our DHCP that will configure will tell the DHCP pooled of the default gateway or if you then for that network is once a 216 10 dot 200 so the switch can receive those and make a routing decision and r1 on that send it to my home router it'll do not send through the service provider network and we can have this Linux box in CML get full access out to the Internet I say full access does the whole internet come with that I mean Internet connectivity you're going to have an old AOL commercial where the person said now if I buy a o.l does that come with the entire Internet the early days all right so let's go to switch one we're already here here's our console for it let's create let's carve out this first of all take a look at the interfaces and this says gig 0 / 2 I was off by one so gig 0 / 2 is connected to our Ethernet box so we'll put gig 0 / 2 inside VLAN 10 so back to the console config T and let's create VLAN 10 and interface gig 0 slash to switch port mode access which port access VLAN 10 I'm using a few shortcuts there but too many shortcuts there oh my gosh oh my gosh I got my cat calm it's a nightmare caps lock off okay switch port access VLAN 10 not so hard alright then we'll do a verify do show VLAN brief right so this shows us that gig 0 / 2 years in VLAN 10 could also to show interface status that would also show us that information which is great and let's create interface VLAN 10 is the logical layer 3 interface on the multi-layer switch IP address me 170 2.16 dot 10 dot 200 I'm using the last octet of 200 for all the switch 1 interfaces and they 3 octet on mask great and a no shut important if you want it to work it needs to be up I just saw the down message all right and let's make a DHCP pool too so IP dhcp pool our pool and we'll say network 172 dot 1610 Network all right 172 that's 16 dot there's some other command that starts with net so my bad so one save to 16 dot 10.0 and I'm asked of 24 bits one of the few times I can do it here on iOS and so we'll use it and let's do a default router of 180 2.16 dot 200 got carried away to dot and that 200 and we can also give them DNS if he wants how about a dee a server let's go 2 8 8 8 8 say hey use Google use a Google DNS server you can hopefully you can reach it if everything set up correctly you should be able to alright exciting times and let's check our work so we'll do a show run section DHCP there's our pool it's for the 10 Network the 10 subnet default router is the layer 3 address of the multi-layer switch DNS server is 888 that looks good to me all right so let's go to a linux box and we'll go to a command prompt there are the console and let's do a ifconfig for ethernet zero oh look all right so that seems almost too good to be true let's see if it it must have been trying in the background to get an IP address because that IP address it just got is in the range let's do a route IP route I don't see the default gateway though so that's a problem so it might have gotten the IP address before I put the default gateway in as far as the DHCP config because I don't see it so if it doesn't have a default gateway it's not going too far let's do this I F config' Ethernet zero down and I think the if' down is that work here oh yeah so I have down Ethernet 0 that also works alright and then I F you do it ifconfig Ethernet 0 up or down because I F up Ethernet 0 it also seems to work here are the yep and ok look at that it got an IP address let's do a route and now it has a default gateway I don't think that was there previously all right so it's important if we want this to work for it to have a default gateway let's do a full shot here let's do a a trace out too wcco.com so the magic of this let's take a moment the magic of this is that if this is going I don't know if it's gonna I hope it's gonna work if this well we looked at a lot of pieces I have pretty high confidence it's gonna work if this works is because the DNS worked first so the DNS resolution is being sent routed out to the internet reading responses coming back and then he figures out what the IP address is the Linux box and then he does the trace based on the IP address fed back by DNS and then I'll show us the hops in the path let's check it out all right final moment here oh my gosh I love it I love it and I love the fact that anybody can practice with things like this and get it working and there's three options that are important this is part of the you know the Keith Parker channels objective is give you the tools and tips today helping you get your CCNA and one of the tips is lab lab lab practice because you saw me come across several thing this isn't working why not and then troubleshooting and walking through it that type of experience is going to go a long long way in getting you to your skinning your skills up and up and up so I'd encourage you here's my call to action please take either a physical lab environment that you have a home or the packet tracer lab you can find that in my master playlist or my packet Rishi lab files or if you have Cisco modeling labs I'd like you to try this as well in practicing getting hands-on connectivity from a home lab out to the actual Internet which is super super fun then if you haven't already joined the channel please do so please click on subscribe don't miss a single thing get the latest tips and tools regarding learn earning and getting your CCNA it's fun to have you here we usually have right after a live premiere of a video like this we often jump into discord server so if if this is the live premiere day we'll do that as well so right after the premiere please jump on the discord server all the link in the description we have a voice chat secnav voice chat so you can just listen hangout chat it's all fun and also on Sundays at 11 a.m. Pacific Time so get out your world clock calendars to just that but 11:00 a.m. Sundays we're doing quiz questions and it's sort of like the marriage I'm a really fun game and flash cards based on CCNA getting together and that's what we do using Kahoot I can only support it it's funny now but I imagine at some point we'll meet meet capacity we can support up to 2,000 people in those games and my intention is for every who wants to participate have a lot of fun get some reinforcements of those concepts join us it is free it doesn't cost the time as do these videos here on YouTube on the keith barker channel and this is meant to be a resource that you can use as part of your CCNA studies again to give you the best tips and tools today regarding getting your CCNA so I'll see everybody in the next live event until then have a great great day and happy studies bye [Music] don't get out what you put in
