WEBVTT 0:00:08.620000 --> 0:00:12.900000 Okay, so here in part two, we're going to be talking about, so you've 0:00:12.900000 --> 0:00:19.080000 made the decision now that you want to utilize someone else's remote equipment. 0:00:19.080000 --> 0:00:22.320000 And you're going to rent time on that. 0:00:22.320000 --> 0:00:23.820000 How do you effectively do that? 0:00:23.820000 --> 0:00:28.720000 How do you choose a provider of what's the best provider to choose for 0:00:28.720000 --> 0:00:32.280000 this? Some things to look for, some tips and tricks. 0:00:32.280000 --> 0:00:37.940000 And how do you design labs that can be used on their equipment? 0:00:37.940000 --> 0:00:42.500000 If you've got two choices, if you're going to follow a pre-designed lab, 0:00:42.500000 --> 0:00:46.880000 like a workbook or something, what are the best ways of using that workbook 0:00:46.880000 --> 0:00:51.300000 so that you are not spending money frivolously? 0:00:51.300000 --> 0:00:56.340000 Or secondarily, if you decide to design your own labs, what's the best 0:00:56.340000 --> 0:01:01.040000 way to do that and also not spend money frivolously on the rented rack 0:01:01.040000 --> 0:01:04.520000 time? So we're going to talk about those topics. 0:01:04.520000 --> 0:01:07.400000 So let's get into it. 0:01:07.400000 --> 0:01:14.180000 So, like I mentioned, before you spend a single penny on somebody else's 0:01:14.180000 --> 0:01:18.040000 remote racks, you have to ask yourself, do a little bit of self-assessment 0:01:18.040000 --> 0:01:22.820000 here, do a little bit of internal thinking about yourself and ask yourself, 0:01:22.820000 --> 0:01:27.720000 what is the best way that you learn stuff? 0:01:27.720000 --> 0:01:33.400000 Is it following a pre-designed lab guide or is it designing your own lab 0:01:33.400000 --> 0:01:38.000000 tasks? Different people have different learning styles and need to answer 0:01:38.000000 --> 0:01:42.580000 this because the techniques for efficient use of labs differ depending 0:01:42.580000 --> 0:01:46.480000 on which one of these you're going to pursue. 0:01:46.480000 --> 0:01:56.220000 So let's start with the first one. 0:01:56.220000 --> 0:01:59.780000 So, there are pros and cons to both of these. 0:01:59.780000 --> 0:02:03.520000 If you're using a workbook or you decide to design and create your own 0:02:03.520000 --> 0:02:05.640000 labs, pros and cons to both. 0:02:05.640000 --> 0:02:08.140000 So let's talk a little bit about that real quickly. 0:02:08.140000 --> 0:02:09.480000 So where are some of the benefits? 0:02:09.480000 --> 0:02:14.020000 Where are some of the positives of using a pre-designed lab guide or lab 0:02:14.020000 --> 0:02:23.640000 workbook? Well, typically if it's a well -designed workbook, in other words, 0:02:23.640000 --> 0:02:27.080000 each task will build upon itself. 0:02:27.080000 --> 0:02:29.540000 So when you start the workbook, it'll start out with something rather 0:02:29.540000 --> 0:02:33.600000 simple, and by the time you get done with it, the tasks have gotten harder 0:02:33.600000 --> 0:02:36.160000 and harder and more and more complex. 0:02:36.160000 --> 0:02:37.300000 They've built on each other. 0:02:37.300000 --> 0:02:41.100000 They're not just scattered all over the place with no correlation to each 0:02:41.100000 --> 0:02:47.380000 other. A good workbook, if it's a workbook that's built around a particular 0:02:47.380000 --> 0:02:52.280000 certification, it will have features and protocols that match that Cisco 0:02:52.280000 --> 0:02:58.680000 certification. For example, maybe you're studying for your CCNP, let's 0:02:58.680000 --> 0:03:04.900000 just say. And right now you're thinking about doing the CCNP route exam. 0:03:04.900000 --> 0:03:12.500000 And you say to yourself, well, if I was to just do my own labs on BGP, 0:03:12.500000 --> 0:03:14.780000 how do I know when to stop? 0:03:14.780000 --> 0:03:21.520000 In other words, do I need to know about route reflectors and confederations 0:03:21.520000 --> 0:03:26.200000 for BGP? Do I need to know what each and every one of these little things 0:03:26.200000 --> 0:03:31.100000 in this show output I'm looking at, do I need to know what they mean for 0:03:31.100000 --> 0:03:33.920000 BGP to pass the route exam? 0:03:33.920000 --> 0:03:38.840000 Well, kind of hard to answer those questions you can, but if you're following 0:03:38.840000 --> 0:03:44.200000 a pre-built lab workbook, hopefully the designer of that workbook built 0:03:44.200000 --> 0:03:49.580000 it so that it's not too difficult and not too easy, right? 0:03:49.580000 --> 0:03:54.880000 A CCNP route workbook should not have you doing tasks where you're configuring 0:03:54.880000 --> 0:03:58.400000 and troubleshooting DMVPN, because that's not something you need to know 0:03:58.400000 --> 0:04:00.580000 for the route exam. 0:04:00.580000 --> 0:04:02.780000 So that's an example. 0:04:02.780000 --> 0:04:07.380000 Workbooks, if they're designed well, should have lots of screenshots to 0:04:07.380000 --> 0:04:09.440000 help you with self-assessment. 0:04:09.440000 --> 0:04:10.960000 How do you know if you're doing it right? 0:04:10.960000 --> 0:04:14.060000 How do you know if you're doing it the way the developer of this workbook 0:04:14.060000 --> 0:04:15.140000 wanted you to do it? 0:04:15.140000 --> 0:04:17.520000 Well, there should be screenshots in there to guide you along to make 0:04:17.520000 --> 0:04:18.680000 sure that, okay, good. 0:04:18.680000 --> 0:04:22.940000 What I'm seeing here matches this picture so I'm clearly on the right 0:04:22.940000 --> 0:04:30.200000 path. It should have pre-built topology diagrams in it as well. 0:04:30.200000 --> 0:04:34.820000 So what I mean by this is, well, I think that's pretty clear pre-built 0:04:34.820000 --> 0:04:37.780000 topology diagrams. 0:04:37.780000 --> 0:04:42.560000 And not every workbook has this, but some workbooks have questions and 0:04:42.560000 --> 0:04:44.240000 assessments to answer. 0:04:44.240000 --> 0:04:48.840000 You know, you might have a task and part of the task might be, okay, before 0:04:48.840000 --> 0:04:54.420000 you configure this command, what's the quantity of router LSA's you think 0:04:54.420000 --> 0:04:56.540000 router one will see? 0:04:56.540000 --> 0:05:01.600000 What do you think the advertising router field will be of the type three 0:05:01.600000 --> 0:05:04.600000 summary LSA that router two is seeing? 0:05:04.600000 --> 0:05:07.560000 So it might ask you a question that forces you to stop for a minute and 0:05:07.560000 --> 0:05:09.820000 think about what you're doing. 0:05:09.820000 --> 0:05:13.200000 You just have blindly sort of in a trance typing in tasks and typing in 0:05:13.200000 --> 0:05:16.240000 tasks and is going through it like that. 0:05:16.240000 --> 0:05:20.160000 And it might have some pre-configured initial configurations as well. 0:05:20.160000 --> 0:05:24.980000 Certainly if a workbook was designed around the assumption that you're 0:05:24.980000 --> 0:05:28.620000 going to be using the exact same equipment that the designer used when 0:05:28.620000 --> 0:05:32.280000 creating the workbook, it might come with some initial configuration so 0:05:32.280000 --> 0:05:34.940000 you can just copy and paste it onto the equipment. 0:05:34.940000 --> 0:05:39.780000 Now what are some of the cons, some of the downsides of using a pre-designed 0:05:39.780000 --> 0:05:44.900000 lab guide? Well, it's not really designed to encourage creative exploration. 0:05:44.900000 --> 0:05:49.260000 It's really designed that you follow each task through, and if you deviate 0:05:49.260000 --> 0:05:52.580000 from the task, you might be messing yourself up. 0:05:52.580000 --> 0:05:56.000000 If you deviate from the task, you might not be able to do the next task, 0:05:56.000000 --> 0:06:00.300000 so it's not really designed that way for that. 0:06:00.300000 --> 0:06:02.180000 Could be poorly written. 0:06:02.180000 --> 0:06:04.860000 And this is something you have to check out. 0:06:04.860000 --> 0:06:07.320000 You know, is the person who wrote that? 0:06:07.320000 --> 0:06:10.040000 Is there a lot of bad syntax in their bad grammar? 0:06:10.040000 --> 0:06:14.620000 And this might seem trivial, but bad syntax and bad grammar in a workbook 0:06:14.620000 --> 0:06:17.500000 could mean that you don't really understand what they're asking of you. 0:06:17.500000 --> 0:06:23.480000 You don't really know what to do or what the objective is. 0:06:23.480000 --> 0:06:27.800000 Failure to complete one section might result in the inability to continue 0:06:27.800000 --> 0:06:31.720000 to remaining sections, so that's also something to consider. 0:06:31.720000 --> 0:06:38.360000 And how that ties back to this previous one is, you know, what if you're 0:06:38.360000 --> 0:06:41.020000 going through lab task number four? 0:06:41.020000 --> 0:06:45.480000 Let's say a lab workbook has 15 tasks on a particular protocol, 15 tasks 0:06:45.480000 --> 0:06:49.240000 on OSPF, and you're on lab task number four. 0:06:49.240000 --> 0:06:52.360000 And when you get to lab task number four, all of a sudden, to your shock 0:06:52.360000 --> 0:06:57.760000 and amazement, that looks like there should be another paragraph or sentence 0:06:57.760000 --> 0:07:03.340000 in there. The thing says, and on R4, configure the command, and there's 0:07:03.340000 --> 0:07:07.860000 nothing. Well, now you can't complete lab task number four, and if you 0:07:07.860000 --> 0:07:11.620000 can't complete that, can you move on to the other tasks? 0:07:11.620000 --> 0:07:15.460000 That might be a downside to a workbook, if the editors didn't catch that 0:07:15.460000 --> 0:07:17.920000 when they put it out there. 0:07:17.920000 --> 0:07:21.400000 And it may not include tasks on protocols or features that you personally 0:07:21.400000 --> 0:07:23.000000 wish to explore. 0:07:23.000000 --> 0:07:26.060000 You know, it might not have everything that you want to do. 0:07:26.060000 --> 0:07:32.140000 So one of the things you have to ask yourself is, under what circumstances 0:07:32.140000 --> 0:07:36.000000 do you retain Cisco iOS commands the best? 0:07:36.000000 --> 0:07:38.640000 Because, you know, the whole reason you're doing this, the whole reason 0:07:38.640000 --> 0:07:42.500000 you're getting on the equipment is to get exposure to the commands. 0:07:42.500000 --> 0:07:46.120000 Not only exposure, yeah, you want to see what the output of the show command 0:07:46.120000 --> 0:07:50.060000 looks like. You want to see what the output of the debug looks like. 0:07:50.060000 --> 0:07:53.080000 You want to become familiar with what this column means and what this 0:07:53.080000 --> 0:07:56.080000 keyword means. But that's not enough. 0:07:56.080000 --> 0:07:59.680000 In order to pass the exam, you have to memorize the commands. 0:07:59.680000 --> 0:08:02.020000 You have to know what the command is I would type. 0:08:02.020000 --> 0:08:05.480000 What show command would I type to see if I'm actually in the established 0:08:05.480000 --> 0:08:08.080000 state or not with my BGP neighbor? 0:08:08.080000 --> 0:08:12.020000 What show command would I type to see if I've got a promiscuous port for 0:08:12.020000 --> 0:08:13.120000 my private VLAN? 0:08:13.120000 --> 0:08:14.660000 You need to know this. 0:08:14.660000 --> 0:08:16.560000 And so you have to ask yourself the question. 0:08:16.560000 --> 0:08:23.580000 For me personally, what is the best way I can memorize iOS commands? 0:08:23.580000 --> 0:08:28.460000 Is it following a pre-designed lab guide where they say, type this command, 0:08:28.460000 --> 0:08:30.940000 see this output, type this command, see this output. 0:08:30.940000 --> 0:08:32.060000 Maybe that works for you. 0:08:32.060000 --> 0:08:34.660000 Maybe when you see that, it sticks with your head. 0:08:34.660000 --> 0:08:39.960000 For me personally, I memorize commands better by experimentation and using 0:08:39.960000 --> 0:08:43.120000 the question mark very liberally and frequently and trying to see what 0:08:43.120000 --> 0:08:46.340000 all the commands are and see what's available to me and trying out various 0:08:46.340000 --> 0:08:49.940000 keywords. That helps the command stick in my brain a little bit better 0:08:49.940000 --> 0:08:53.660000 than reading through somebody else's document that says, use this command, 0:08:53.660000 --> 0:08:54.840000 use this command. 0:08:54.840000 --> 0:08:56.080000 But it's your own personal style. 0:08:56.080000 --> 0:09:00.020000 You have to know that. 0:09:00.020000 --> 0:09:03.820000 Okay, so let's say that you decide that you do want to use a lab guide. 0:09:03.820000 --> 0:09:09.520000 So as we can see here, lab guides are written based on one of two assumptions. 0:09:09.520000 --> 0:09:14.040000 The first assumption will be that you as the customer have access to the 0:09:14.040000 --> 0:09:16.340000 same equipment as the lab developer. 0:09:16.340000 --> 0:09:19.640000 Other lab guides will not make that assumption. 0:09:19.640000 --> 0:09:23.640000 They will say, hey, look, here's a lab I developed in GNS3 or here's a 0:09:23.640000 --> 0:09:25.620000 lab I developed on my home rack. 0:09:25.620000 --> 0:09:30.040000 But it will be up to you to recreate that somewhere else. 0:09:30.040000 --> 0:09:33.480000 You will need to find or build your own topology to match that of the 0:09:33.480000 --> 0:09:40.660000 lab guide. So my personal advice is not just because I work for INE, you 0:09:40.660000 --> 0:09:43.540000 know, I am a little influenced that way, but my personal advice is that 0:09:43.540000 --> 0:09:46.960000 if you decide to use a pre-design lab guide, select one that allows you 0:09:46.960000 --> 0:09:50.800000 access to the same equipment as that used by the lab designer. 0:09:50.800000 --> 0:09:54.960000 Why? Well, there's a lot of reasons for that. 0:09:54.960000 --> 0:10:00.680000 If you're using a lab guide that was built by someone and you don't have 0:10:00.680000 --> 0:10:04.980000 access to the exact same hardware as they do, for example, let's say they 0:10:04.980000 --> 0:10:08.440000 built something in GNS3, okay? 0:10:08.440000 --> 0:10:14.240000 Well, you might not have access to the exact same iOS images that they 0:10:14.240000 --> 0:10:17.280000 used in their GNS setup. 0:10:17.280000 --> 0:10:20.660000 Or let's say they built something on their own home rack. 0:10:20.660000 --> 0:10:22.440000 You don't have access to their home rack. 0:10:22.440000 --> 0:10:23.440000 So what's that going to mean? 0:10:23.440000 --> 0:10:27.540000 Well, that might translate to you might not have access to the same quantity 0:10:27.540000 --> 0:10:29.880000 of interfaces as they do. 0:10:29.880000 --> 0:10:33.960000 Maybe in the lab they designed they have got seven serial interfaces and 0:10:33.960000 --> 0:10:36.520000 the best you could come up with is five. 0:10:36.520000 --> 0:10:38.800000 That's going to be a problem. 0:10:38.800000 --> 0:10:43.260000 You might not have access to the same types of interfaces as they do. 0:10:43.260000 --> 0:10:46.160000 Let's take serial interfaces once again as an example. 0:10:46.160000 --> 0:10:48.620000 Some serial interfaces are slow speed. 0:10:48.620000 --> 0:10:51.680000 Some serial interfaces are high speed interfaces. 0:10:51.680000 --> 0:10:57.160000 If they built their lab using high speed serial, but all you've got access 0:10:57.160000 --> 0:11:00.260000 to is low speed serial, that's going to be a problem because now your 0:11:00.260000 --> 0:11:05.100000 OSP of cost, your EIGRP bandwidth is going to be different than what they 0:11:05.100000 --> 0:11:08.640000 came up with when they develop the lab. 0:11:08.640000 --> 0:11:13.840000 If they supply any precon As we can see here, 215 00:09:06,683 --> 00:09:08,210 lab guides are written based on one of 216 00:09:08,210 --> 00:09:10,177 two assumptions. 217 00:09:10,177 --> 00:09:13,060 The first assumption will be that you, as the customer, 218 00:09:13,060 --> 00:09:17,318 have access to the same equipment as the lab developer. 219 00:09:17,318 --> 00:09:19,471 Other lab guides will not make that assumption. 220 00:09:19,471 --> 00:09:23,114 They will say, hey look, here's a lab I developed in GNS3, 221 00:09:23,114 --> 00:09:25,947 or here's a lab I developed on my home rack, 222 00:09:25,947 --> 00:09:30,074 but it will be up to you to recreate that somewhere else. 223 00:09:30,074 --> 00:09:31,542 You will need to find or build your 224 00:09:31,542 --> 00:09:33,485 own topology to match that of the 225 00:09:33,485 --> 00:09:39,909 lab guide. My personal advice - and it's not just because I work 226 00:09:39,909 --> 00:09:41,844 for INE, I am a little influenced 227 00:09:41,844 --> 00:09:43,371 that way - but my personal advice 228 00:09:43,371 --> 00:09:45,827 is that if you decide to use a pre-designed lab guide, 229 00:09:45,827 --> 00:09:47,507 select one that allows you access 230 00:09:47,507 --> 00:09:49,355 to the same equipment as that used 231 00:09:49,355 --> 00:09:50,762 by the lab designer. 232 00:09:50,762 --> 00:09:55,383 Why? Well, there's a lot of reasons for that. 233 00:09:55,383 --> 00:09:57,840 If you're using a lab guide that 234 00:09:57,840 --> 00:10:00,509 was built by someone and you don't 235 00:10:00,509 --> 00:10:04,102 have access to the exact same hardware as they do, 236 00:10:04,102 --> 00:10:08,331 for example, say they built something in GNS3. 237 00:10:08,331 --> 00:10:11,645 You might not have access 238 00:10:11,645 --> 00:10:13,918 to the exact same IOS images 239 00:10:13,918 --> 00:10:16,787 that they used in their GNS setup. 240 00:10:16,787 --> 00:10:18,910 Or let's say they built something 241 00:10:18,910 --> 00:10:20,740 on their own home rack. 242 00:10:20,740 --> 00:10:22,534 You don't have access to their home rack, 243 00:10:22,534 --> 00:10:23,423 so what's that going to mean? 244 00:10:23,423 --> 00:10:25,604 Well, that might translate to you 245 00:10:25,604 --> 00:10:27,204 might not have access to the same 246 00:10:27,204 --> 00:10:29,863 quantity of interfaces as they do. 247 00:10:29,863 --> 00:10:31,269 Maybe in the lab they designed, 248 00:10:31,269 --> 00:10:33,688 they have got seven serial interfaces 249 00:10:33,688 --> 00:10:36,632 and the best you could come up with is five. 250 00:10:36,632 --> 00:10:39,113 That's going to be a problem. 251 00:10:39,113 --> 00:10:41,000 You might not have access to the 252 00:10:41,012 --> 00:10:43,266 same types of interfaces as they do. 253 00:10:43,266 --> 00:10:46,183 We'll take serial interfaces, once again, as an example. 254 00:10:46,183 --> 00:10:48,791 Some serial interfaces are slow speed. 255 00:10:48,791 --> 00:10:51,708 Some serial interfaces are high speed interfaces. 256 00:10:51,708 --> 00:10:54,631 They built their lab using high 257 00:10:54,631 --> 00:10:56,928 speed serial but all you've got 258 00:10:56,928 --> 00:10:59,636 access to is low speed serial.
