CCIE R&S v5 Lab Configuration Section

so you've sat through two hours or two and a half hours of troubleshooting you've sat through 30 minutes of diagnostic tickets where you've essentially read through a thousand pages of junk and figured out what the problem isn't and now you're at this point where you need to actually configure everything now what I want to do is I want to back up here for a quick second I want to make sure that you understand that the troubleshooting section is going to be where a Cisco essentially tries to really test your ability as a CCIE most of the candidates that I deal with most of the folks that I teach if they can make it to the config section without a problem most of them pass you need to have patience though because in the configuration section you are going to go through a lot of devices having to configure a lot of different technologies and you're really going to be tested you're going to have to have a lot of patience you're going to have to be able to work through frustration because you're going to be asked to do a lot of different things and you're going to have to do it a lot of different times you know you you're going to have to implement OSPF a dozen times yeah GRP a dozen times BGP twice as many times I mean you're going to have to do a lot you're going to be implementing the same things in succession and and it's going to be very repetitive okay so you need to have patience and you need to really be able to work through a very high frustration level the other thing that you're going to really need to do in order to get past this section is to be able to work under just sheer exhaustion I mean you've you didn't sleep the night before you woke up at 6 o'clock in the morning so you maybe you've had three or four hours of sleep you get to the testing center you've sat through to two and a half hours of troubleshooting tickets that are just up not just and stupid you've gotten past it then you had to read all this obnoxious amounts of information you were able to successfully pass it now you've gotten back from lunch and you're even more tired because you took lunch now don't don't misunderstand this here you have to take lunch the proctor is not going to allow you to sit in the lab center or bypass lunch everybody has to leave for a half-hour lunch period ok now Cisco is going to provide you lunch they try to make all dietary needs met so there is going to be salad there for vegetarians it's going to be like grilled chicken or some pasta there's going to be some cookies for those you guys that have a sweet tooth maybe some chips couple cans of soda and some water so they try to make sure that everybody has you know their dietary needs met you can bring your own lunch again and I explained that in the first video of this series that they will ask to see your lunch to make sure that you're not trying to smuggle anything in but you've gotten back from lunch and now you've eaten a meal and you're even more tired if you're those guys that are sugar high well you're going to be good for the first two hours of configuration and then you're going to crash right you know you're going to fall asleep right this is going to be the the I want to say the most physically challenging piece of your exam ok let's take a look at it again you see the diagram behind me it's not terribly different than what we saw in troubleshooting same size topology same amount of devices but a different topology over all the menus across the top are going to be very very similar with the exception of these two so for this discussion I'm only going to concentrate on essentially these two because Same Same Same Same okay they're all going to be generally the same if you cook in session you're done helping settings same thing manage devices same thing you can console you can reboot your devices etc important guidelines this is where it's going to tell you not to add any additional interfaces or add any you know you can't and when I say interfaces I mean loop backs obviously you're not allowed to configure any new IP addresses or anything like that essentially what you have is what you get unless you're specifically asked to violate one of those principles in other words they may ask you to create a loopback in which case you would create that one loopback but don't go creating them on your own you know I heard a story wants a very funny story to me anyway some guy took his lab exam and knew that he was going to fail knew that he was just done I mean he was in this config section I knew that he didn't have a prayer and so what he did was he spent hours configuring loopback addresses on all of the devices so that no matter what device you were on when you ping that address it would be successful because each device had loopback addresses to everybody else's IP addresses and so you had full reach ability if I thought that was kind of clever but essentially again here I'm just going to concentrate on these two buttons here the requirements in the initial uh the additional diagrams now in the lab this the config section is exactly like the de Paula the troubleshooting where if I click on any one of these devices it's going to pop my telnet client now you notice something different about this topology and I just circled them and that's these switches that are in the middle and you also notice that I have this switch here that's actually cabled into my devices it is important for you to understand that this is my layer 3 drawing okay it's actually a combination of layer 2 layer 3 what do I mean by that well physically here it looks like router 9 is cabled into switch 1 and it tells me Ethernet 0 0 here and it just tells me dot 14 there I don't know if you guys can read it that's why I'm expressing it to you tells me here that there is a VL 9 10 that VL is going to stand for VLAN so I have another one here another one here here here here and here and I have more throughout this topology so there's more VLANs that are associated even though router 9 looks to be directly cabled into switch 1 that doesn't mean that it necessarily is router 9 could be going into switch 2 and then connecting to switch 1 so this is not going to be my layer 2 diagram essentially showing me all the physical cabled connections that are done within my virtual rack at Cisco this is telling me my traffic pattern where should the packets flow within my network your job is to make this so now the problem that I find in most cases here is how do I go and create all these different VLANs here right how do I go through this and what I want to do is I want to bring in my my command prompt here and this is just my command prompt and what I want to do is I want to show you guys just how I did this so I see all these VLANs here right I see I see in my diagram I see that I have these VLANs listed here so I have a VLAN here I have a VLAN here I have all these right and it's telling me on each router what the interface is on each router that's connected that needs to be an access port essentially as a member of that VLAN now in case you're wondering these three switches here in my layer 3 diagram are telling me that these switches are involved at layer 2 but they are not involved at layer 3 meaning these guys are just my pass-through switches so what I would do here not forgive me this is only a command window right so the commands aren't going to work but what I would do here is say show CDP neighbor ok at that point what would happen when I do show CDP neighbor in this telnet window here ok so in here it's going to print out for me the list of all the devices on this switch that are plugged in at that point I can say alright I'm on switch 2 and I see that I'm connected to router 9 and I see that my local interface could be Ethernet zero zero and I see that my remote interface on router nine is Ethernet zero zero so what am I going to do now I know that I need to go on to my Ethernet zero zero and I need to say switch port mode access switch port access VLAN nine ten so that's how this is going to be laid out and what I always recommend to my students and a lot of them disagree at first but ninety-eight ninety-nine percent of them always come around is don't use the layer two diagram that Cisco gives you because you got to imagine you have twenty something routers you have eight to a dozen switches or eight to ten switches that's a big physical diagram to really look at and it's going to take you time to match the physical diagram to the to the logical diagram that you see behind me here and cisco has already given you the interfaces again right here they've already given you these interfaces that the devices are connected to so using CDP neighbor you can easily go into these devices here and see who's connected to who and put them in the right access VLAN okay and you see this example here again all right so so what I wanted just delete that all right so this is how I would approach and this is in fact how I did approach the configuration section in my lab all right I just simply brought up my my telnet session here for switch 1 or switch 2 shows CDP neighbor and I began to put all these interfaces into the right VLAN okay I did not use the layer 2 diagram at all in fact that wasn't even positive if they gave you a layer 2 diagram because I didn't use it I was done with the layer 2 portion of my config section within 30 minutes okay and it can absolutely be done and I've had a lot of students that go through and they try to match up the layer 2 diagram with the layer 3 diagram and it takes them an hour and a half to finish layer 2 then I have students that use my method and just do show CDP neighbor and they get proficient at that and they move up their time to about a half hour so it can be done I'm recommending it to you for a reason you don't have to use my method you could use another method as long as it helps you to save time as long as it helps you to get it done quickly all right so now this is again going to be your the background to your diagram so just like in troubleshooting this is this this topology here is going to be the background it cannot change no matter what you load this diagram always stays the same and all of these are going to be hotspots now when you click on requirements the requirements hang on one second here guys let me just get this perfect here so the requirements are going to just like in troubleshooting they're going to expand the list of requirements so you're going to have all these requirements here the thing to note about these requirements and what I want you to focus on is that they are in order based on the blueprint so the CCIE version 5 lab loop blueprint by the way and I'm having a thought here while I'm speaking that's why I just stopped in the middle dead sentence there is two different blueprints you realize that for routes which we have a written blueprint we have a lab blueprint they are very similar but they are also very different make sure you download the right blueprint make sure it says lab on it but these are going to be laid out in the section of the blueprint now that's a good thing and it's also a bad thing what do I mean by a bad thing well I'm going to scroll up here for a second back to my main diagram and I believe it's going to be over on this side so here you see here I don't know if you guys can see it but I have interface here and then I have three tunnel interfaces here now I don't know again if you guys can see it but I have AI GRP five five five running right here and I also have AI GRP five five five running down here so I have e IG RP I have an IG P that needs to extend over a dmvpn well in order for me to do this I have to have BGP running between these guys in order for me to have physical reach ability between the physical interfaces in order for me to actually have reach ability to the tunnel interfaces right I mean that's kind of the order of operations however let me scroll back down to my requirements list here and I want to show you something the requirements that I need to do are going to be in these following sections so the first half of section 3.0 is going to be IGP so the four I'll write it over here so we're going to have our I GPS first and then I GPS and then we're going to have our a GPS okay so EIGRP in here and BGP over here so what comes first the first thing that I'm going to read in my lab is going to be EIGRP over that diem VPN tunnel but I haven't gotten to the BGP section that tells me how I need to get reach ability between essentially this is P here that you see in the background and the rest of those routers the hub and spokes I haven't gotten to it yet because I'm still in the first half of section 2 0 which is my layer 3 technologies well so I need to do this first before I do this but I'm already in this section that means I need to skip this section make a note of it write it down on my piece of paper skip it and go down to the BGP section once I get BGP up and running can I go back to yeah GRP no I can't why because I need to get the dmvpn up and running before you know between the hub and spokes before I go to the EIG RP section that means I need now to leave a section to zero and I need to go to my dmvpn section which is in my VPN technologies and I need to get my dmvpn up and running once I get my DMV P up and running I can cycle back to that AIG ARP section now I know that sounds confusing but believe me if you do not do it in that in that order or something like that order okay you don't have to use the order of operations that I'm telling you okay I've had many students that say you know what I did it another way it was very similar but I did it my own way and it worked out perfectly regardless what method you use every single student that I've had that said I went down bullet point by bullet point by bullet point by bullet point have said I failed and they all said I was so confused I didn't you know I didn't even know what to do with myself you can't I go down bullet point by bullet point you will get yourself completely confused you will not know what's going on okay what you need to do is you need to think like an engineer that's what I tell my students think like an engineer if I walked into a company and they said hi JP how you doing today I would say hi how are you and they would say you know we need to get a dmvpn up and running between our centralized office or California headquarter office and these three remote offices that we have you know we just got our service provider up and running so can you help us I would say sure the first thing I would make sure is that I have service provider reach ability between all of these hub-and-spoke interfaces right I mean think like an engineer what would you do first you wouldn't go down the bullet points that the company gives you because you're and ie you know better okay you're not going to go down the bullet points that Cisco gives you because you're an ie Cisco has purposely put things in that order for a reason to confuse you you have to think through that and think like an engineer so what would I do first the first thing I would do is I would say hey I want to get reach ability first between my hub and spokes I need to make sure that the public interface or my serial interface here here here and here I need to make sure they can physically reach one another because that physical interface is going to be what I'm using as the source interface for my dmvpn once I do that in order for me to get eigrp up between these two locations sorry about that I accidentally erased my line in order for me to get AI GRP up and running between these two locations assuming I have this service provider reach ability is what I need to next build my tunnel so that's going to be my step - right so this is step one here here one here step one here and my step two is my tunnel then I'm going to build my tunnel interface so I build my tunnel essentially between these guys here sorry for the mess I'm not Bob Ross I'm not a painter I'm a CCIE so so now I've essentially completed my dmvpn tunnel now I can light up a IG RP between these two or four or five or however many locations you're going to have in your lab so you need to tackle your config section as an engineer you need to think like an engineer you cannot go and say well I'm going to do all these things by bullet point because what's going to happen is when you get to that golden moment what is the golden moment every single CCIE lab has what we call a golden moment it's the moment where they ask you to verify that something works and every lab every track has it I don't know what they are in other tracks is I'm around switch guy when you get to that golden moment in your lab they're going to say perform this task and this is what you should get and you're going to perform that task and it's not going to work and because you've gone down all these bullet points in exact order you are literally going to have absolutely no clue on what's not working and why you have to think like an engineer and actually deviate from the bullet points that they're giving you and go at it from a logical perspective not the way that they give it to you all right I really hope that that's clear so when you click on that particular section so here I've gone ahead and said I want to load section 1.0 which is going to be the first one you have to hit for everybody because reach ability first right thinking like an engineer reach ability first you're going to load that you're going to click on requirements you're going to click on section 1 it's going to load a second page it's going to be a pop up page just like we saw on troubleshooting it's going to give you the total amount of points it's going to say this is your section your layer 2 section then what it's going to do is it's going to lay out the requirements for different sections and it's going to give you the points now these could be depending on the version of lab you get these can be based on autonomous system it could be based on an office there there's different revisions of this exam and so you're going to have to read ok where am i performing this configuration task and what do I need to do in order just like we saw diag in order for you to get these two points and and they're very low points it's not like one or two points in order for you I'm sorry it's not like four or five points in order for you to get these two points you have to accomplish every one of these bullet points there is no half credit if I do not get this bullet point I do not get the two points period you have to accomplish all bullet points under that section in order for you to accomplish and get those points now Cisco is going to give you some one-off features here and there in your bullet points and your requirements that you may not know the way that cisco has laid this out is that it's not like you can skip the whole section for example if I skipped this whole section behind me that I've kind of scribbled on I wouldn't have any reach ability between my devices so can I skip it no I have to perform all of those tasks however the one task that I may not know or the one I might be confused on is going to be one that is not essential for the lab to work so if I don't know it I'm going to have to skip it I'm going to have to make that conscious choice to leave those two points behind and continue on in my lab but my lab is still going to work if I just skip this entire section nothing's going to work because I haven't created my VLANs I haven't done any of that you know they may give you a one-off featuring rip for example and you may say well I don't know how to do that in rip but you're still gonna have to perform the other three or four tasks and rip in order for your routing to actually work that one-off task is not going to prevent rip from actually working and actually routing and actually doing what it's supposed to do it's going to be some type of administrative feature that they're going to want you to add or change alright so be aware of that you can't just there's not going to be partial credit that's what some folks that I talk to are confused on they think that well you know each bullet point is going to be just just a small percentage of those points no it's all or nothing all the bullet points for the section for the two points or you miss one you don't get any so we're going to go down here we're going to we're going to accomplish all of these tasks when you're done with layer two that will tackle all of your layer two requirements when you're done with section 2.0 for layer three that's going to tackle all of your routing requirements each and every single one of these are going to be based again on what you see in the blue okay so you're not going to have any dmvpn requirements here you're going to have the routing requirements over the dmvpn here but you're dmvpn requirements are going to be here in VPN same thing with your layer 3 VPN your MPLS requirements etc they're all going to be in your VPN requirements you're not going to find any of those in your layer 3 because they're not in the layer 3 section ok now that being said when you click on any one of these sections it is going to open up a separate page that gives you all those requirements you can then minimize this you can close you can keep it up on another screen I'm going to scroll up and tell you quickly what I did I opened up just like I said before I think in the troubleshooting section I opened up every single device in numerical order so I started with my switches switch 1 2 3 4 5 6 7 8 then I started with my routers router 1 2 3 4 all the way up to 27 or whatever the max I had and then in this case I would start I would end with meeting my ISPs so I would say is P 1 2 1 2 3 & 4 ok so that's how I would open up all these devices the drawback again remember in my first video that these machines aren't incredibly fast they are pretty slow and if you open up the more windows you have open the more resources that you're going to use and so for me I sacrificed leaving the requirements open all the time for leaving all my putty windows open all the time it was less confusing for me so I would go and I would click on my requirements I would read through the requirements of that particular section I would close them I would go to that section I would configure it the way that I wanted to I would go up to requirements sorry let me scroll back up over here I would click on requirements I would then you know click the section read through this section again make sure and verify that I did it properly then I would scroll down and read the next set of instructions I would close this out and that's how I managed my system resources you don't have to take my recommendation you guys need to come up with your own but do something you have to do something in a way that's going to help you to manage manage the lab and manage the requirements ok now additional diagrams this is going to be one of the most important things that you could not forget so in the additional diagrams again this this section of your lab never changes the background of your lab here all these devices they never change they're always there every additional window that you open up is always going to be a pop-up window however this is one of your golden tools that Cisco's given you this is actually going to show you packet paths in your different technologies so for example here what I'm highlighting in red is actually a vrf that we have in our particular network diagram so here under the VPN diagram under the VPN requirement I'm actually showing you this is how this vrf is supposed to traverse the network looking at the main diagram if I scroll back up looking at the main diagram I honestly have no idea how the vrf is supposed to route who it's supposed to go to I don't really have a clue it's it's on there on the diagram okay so it so it is here it is listed here so I do have some idea that we are going to have this vrf in some way shape or form but I don't know how it's going to route I don't know what the requirements are around the the vrf in it by itself however under the additional diagrams section in my pointer back under the additional diagrams I can now see that this vrf is supposed to route to these spokes here okay this is a PE router it outlines that here this is a peer outer PE router and so it tells me these are all PE routers so now I know how to configure them okay so you're going to have additional diagrams you're going to have additional resources for example your layer two diagram you're going to have an extra maybe a bgp diagram maybe one for ipv6 i mean it depends on the version of lab that you get but you're going to have additional diagrams to look at that's going to give you more information based on that technology that you're looking at so if you're in the BGP section and you're just confused out of your mind on how BGP is supposed to work if you see that I'm supposed to peer with this is P and you really just have no idea on how you're supposed to do that may be a good idea for you to go in and look at your additional BGP diagram or maybe your VPN diagram which is the one that I have up right now so that you can see exactly how your layer 3 VPN is going to be configured and how it's going to work and that is what's going to give you the right the right basis in order for you to the right basis in order for you to configure BGP properly so you're going to have to leverage all these different resources together to come up with these requirements all right so the config section is not going to be really hard it's going to be more time-consuming than anything you're going to have to really be fast you're going to have to really just understand how protocols work how they work you're going to have to understand that technology and you're going to you're going to have to go through all of these requirements in an order that makes sense that is probably the biggest tip the biggest thing that I could give you is do not follow these by bullet point meaning do not follow them by section so I don't expect you one two three four and then maybe here you ran out of time no you're going to have to do maybe something like this maybe you tackle this one first you tackle this let's say two let's say one in the air 2.5 2 and a half right and then you go here but you do that three and a half and then you come back here for four and then you come back here for five and then this is six and seven right so you're going to have to go back and forth between these sections you absolutely have to think like an engineer if you don't think like an engineer you're going to have a lot of problems getting through the config section if you go bullet point by bullet point so again reach out to me with any questions I tried to give you guys as much information as I really can I'm always available for questions it may take me longer to respond but you know that's part of my job so I will respond just have patience with me I will do my best to get back to with regards to any of your questions but I hope this video has kind of shed some light on the on the exam sections that you're going to go through and keep on studying and get those numbers you
