This Cisco ARCH video training course with Jeremy Cioara covers the professional-level content you need to design an enterprise-grade network from the ground up, as well as prepare for the Cisco CCDP Cisco certification. The breadth of knowledge covered in Cisco ARCH is tremendous, so be sure you go through CBT Nuggets' Cisco ROUTE and SWITCH courses before diving into ARCH!

Often, Cisco engineers feel they are simply kept on staff to “fix something if it breaks.” Nothing could be further from the truth in a well designed network. Cisco engineers should be in a constant and perpetual state of Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO). In this course, we cover a tremendous breadth of information dealing with implementing network systems the right way, from the beginning. You also learn to bring a system that is slightly off kilter (or perhaps very off kilter) back into a good design. This training also can prepare you for CCDP Cisco certification. The course focuses primarily on three topic areas:
  • Enterprise campus infrastructure network fabric (layer 1/2) design
  • Enterprise campus infrastructure IP address and routing (layer 3) design
  • Enterprise data center design

Welcome to ARCH

00:00:00

Hello, and welcome to the Cisco ARCH series. My name is Jeremy Cioara, and I cannot convey to you the amount of excitement that I am restraining right now. See, here's the deal. This Nugget is the last Nugget that I record of the series. And this is the longest series that I've created in a long time, 50 Nuggets of design, love, coming together to give you the most amazing package that you will ever have on how to design a Cisco network.

00:00:31

Oh, there's so much I can say right now. But this is supposed to be the welcome slide, so welcome to the course. The thing that is so awesome-- obviously, I'm right back into it, right? The thing that is so awesome about this ARCH series is, first off, from a certification perspective, it's one exam.

00:00:50

If you've already gotten the CCNP, which most people do by the time they get here. You've already taken the route and switch exam. And by the way, prerequisite information, I would highly suggest going through those two series or taking those two exams before you get here.

00:01:02

Now when I put these 50 design Nuggets together, I tried to put a brief description of what it was I was talking about with every single topic before I talked about the design principles. So if you haven't taken those, you're not going to be completely out in the wind.

00:01:17

But you're just going to have a much richer experience when you do that. But, anyway, you probably already have those two exams, so just getting ARCH adds a full 'nother professional level of certification, CCDP, which people look for. People have started realizing there's a whole lot of difference between somebody who can implement a protocol, right, CCNP type person, and somebody who can design the right way to implement that protocol, right?

00:01:45

There really is. I mean, there's a divide. I got smoked when I first got getting into network consulting because I was an implementer. I had my CCIE. I knew what I was doing from an implementation perspective. But when someone came to me and they're like, dude, I want you to design this network from scratch.

00:02:02

I'm like, what do you mean? It was almost foreign to me because I was like, I can fix something if it's broken, but I don't know. Do you want three routers or four? It became one of those kind of things. So there's a big difference between implementing and designing a network.

00:02:21

Now, this exam, or I should say the series, is based around the 642-874 exam-- which I just found out, as I was 10 Nuggets away from finishing-- Cisco decided to revise it. And I can't tell you how great of a day that was for me. Because I was like, oh, no, what, seriously?

00:02:41

So at the end of 2015 this exam goes away and is replaced by this exam, but that's OK. I've put right on the screen, Cisco's already published. It's not a major upgrade because it's just more of a refresh of some of the technology that's out there. These are the things that go away.

00:03:00

These are the things that are going to be added to the new exam coming up. So what I'm planning to do is once that exam is out there, probably around the beginning of 2016, I'll release an update pack for this series, which will prepare you for the new topics that exist on 300-320.

00:03:15

Well, before I launch you into this series, I've got one more slide, which may very well be the most valuable slide of the series right here in the first Nugget. I'm obviously not too good at marketing. I'm like, this is as good as it gets, guys. The reason I say that-- the whole series is awesome.

00:03:30

But this slide represents something a little bit different. It really represents what I can teach and what you will have to learn. Let me explain. There are three things from this list that you will be able to learn throughout this series, first redundancy.

00:03:47

You'll learn principles and design practices to make a network environment redundant. It's simple, right? Two is one. One is nine. If you want the device to be redundant you have to buy two of them. You have to weigh the cost, versus the benefit to the organization to implement that redundancy.

00:04:03

And then you've got to have the technology to tie it all together, whether it be a well-designed routing protocol, a first-hop redundancy protocol to make two devices act as one, Nonstop Forwarding, Stateful Switchover to make supervisor engines in a 6500 series switch to lightning fast failover if one of those things freeze.

00:04:21

I mean, these are all things that can easily be taught. And that's going to be a lot of what you learn, along with the tools that you'll use to manage and design the whole network so that you can be proactive, right? So that you can know when a problem is happening before the rest of the users do, and take action before it becomes a major issue in all the documentation that you're going to need to tie it all together.

00:04:44

These are principles that can be taught. But compared to the other two, one might even say that those principles, those three that I've highlighted so far, are actually the easy ones. I know, I'm just not good at marketing at all. You're like, well, all you're going to teach me is the easy stuff.

00:05:04

No, no, no. I mean, you've got to know how the technology works. You got to know the proper way to design it, right? But I think the best way to explain it is to give you my life lesson. This is my 20th year of training. Oh my goodness, it freaks me out to say that.

00:05:19

I started back in Novell. I was there, and then I went to Microsoft, and then Cisco, and then Amazon Web Services. I have seen a ton of technology over the 20 years of training. But five years ago I did something a little crazy. That's what my wife says, so I think so too.

00:05:36

I started a company. I went part time training. And I said, I'm going to start a company that actually does what I taught over the last 20 years. And it's been probably the most painful years of my life. I say painful in a good way. I'm like, how do I say this?

00:05:52

Because I've learned, oh my goodness, I always thought that wasn't that big a deal. And, wow, that just cost me a full weekend's worth of sleep. Oh, I didn't even think that was important. And I've learned-- obviously, I'm running an organization now of 20 people, network engineers.

00:06:10

I've learned that the kind of people that I bring in really can make or break the organization. And let me tell you, I've learned that it's not just the people excited about the technology. It's the people that have these attributes that will really bring you to success.

00:06:29

And there are the red ones. They're very hard to find. I can actually find a lot of people, and I can even grow people that are excited about technology because I'm super excited about technology. I'm like, this is awesome. And these are the people that get in and they're like, oh, and then, bam-- and then bam.

00:06:43

And then ta-da, check it out. And everybody's like, woo-hoo, network's running. But then sometimes those people are the ones that are like, OK, [EXHALING], that was good. Look at the clock. It's 11 o'clock at night. They're like, well, inner monologue mode right here.

00:06:58

I should document what I've done. I should create a change. I should email the team. Let them know this is done. I should email the customer and let them know implementation was successful, or I had to roll back. But I'll do that when I get home. And they get home, and they're like, oh, I'm tired, enough.

00:07:15

Adrenaline rush is gone now. I'm going to bed. That doesn't happen. And, essentially, what's created is a hole in the system. That six months, nine months, a year later suddenly implodes, and the whole system goes down. And everyone's like, whoa, I never even saw that coming, right?

00:07:32

Those are the kind of things that I look for in people now when I'm hiring. And I've got a whole bunch of people that I interview. A lot of them are excited to jump on board. A lot of them are excited about technology. But when I really start asking the question, I'm like OK, are you a detail oriented person?

00:07:47

It's not the kind of questions that you might think. It's not, well, can you tell me how do you configure OSPF in a multi-area system? You know the kind of questions I ask? I don't want to give away my interview. But I'll be talking to somebody. I'm like, hey, you mind if we go to your car?

00:08:03

Open your trunk. I'm serious. I've done it-- I've done it. I've been in the parking lot, and I'm interviewing a guy, and I'm like, you're pretty good. Let me see your trunk. And he opens it up, and I'm like, [GASP]. There's In-N-Out Burger wrappers in there.

00:08:16

There's stuffed shells. There's a couple folders that are crinkled up in the back. And he's, like, what? And I'm like, no, just looking, just curious. And I'm like, we'll give you a call. Not going to bring that guy on-board. What do you mean-- what do you mean?

00:08:28

He knew what he was doing with OSPF. He knew what he was doing. He's been in the field for 10 years. He knows his stuff. Yeah, but you know what? His trunk wasn't clean. I know what you're thinking right now. You're like, I'm cleaning my trunk. No, what I'm talking about is there's a kind of person that will make or break a network design and a network implementation.

00:08:51

And it's the kind of person-- I'm just giving you one element. I'm not going to give away the rest of my interview techniques. But these are the questions that I ask to hone in, to find these kind of people. The people that will say, you know what, I could just go implement, or I could take an extra day-- yeah, day, week-- to implement a lab environment, and actually test what I'm doing before I schedule the outage [INAUDIBLE] go out there and type in the commands and figure it's all working and all well.

00:09:17

And then I found out a week later that it's actually causing major loss on a lot of the file transfers, and nobody's really been freaking out. But the speed of our entire network has gone down by 30% over the last-- ugh. Those are the kind of things that you run into.

00:09:31

So, people, that's my first element. Processes-- this is heavy stuff. Oh my goodness, this is heavy for the first Nugget of the series. But I've got to convey it now because I'm telling you, through this rest of the series, you're going to get so excited about this technology.

00:09:44

You're going to be, like, I can design a network. And I've got to convey it now, or I never will. On processes-- people and processes-- you've got to start creating processes that are repeatable, meaning, yeah, you implemented OSPF. And you type the commands as you go, but could you do it again, the same way, every single time?

00:10:00

You know that it's going to take you an hour to implement that. How do you know that? Because you created a process. You know these are the lists of commands. Here's the verification commands. Here's the things that I'm going to implement to make sure that this system is working well.

00:10:17

Am I disciplined enough to follow my change control process? Oh, I just thought of it. There is a book out there. Hopefully, I can pull it up. It's called The Phoenix Project. Read that book, please. The Phoenix Project-- it is right there. It looks kind of fun, right?

00:10:37

What it is, is it's a fiction story on implementing the principles of ITIL. I don't know if you've ever heard of the IT Infrastructure Library. Chris Ward, here at CBT Nuggets, does an awesome series on it. Essentially, ITIL is the right way to design and operate-- I'll say a network-- but I'll just say IT systems as a whole.

00:10:56

But the problem is it's so big, everybody's confused of where do I even start with it. Read that book, please. Do me a favor. Before you get into a career of network design, just read that book. It's a fiction novel of a guy who gets hired into a business that essentially gets promoted to CIO, or something to that effect.

00:11:17

And you just watch his world crumble around him because of lack of process, lack of people that are following a process. Change control is the number one element that will make or break a system, meaning change control-- let me just make sure I define it well.

00:11:32

Change control is-- how do I even describe it? Change control is, how do I ensure the changes that I'm going to make aren't going to affect the system? Can I through out a statistic? 80% of outages are caused, not by the system, but by IT people. So right now I'm feeling like, how did this Nugget get this way?

00:12:00

I've got to keep this in here because it's so real. IT people can be a major issue, 80% of them, to be exact. Of the issues that occur in a system, change control is your number one way of preventing that. So those are the two. I spend so much time on them on this opening Nugget-- the people and the procecces-- because that's it.

00:12:21

That's all I have to say on those two elements. But I can tell you, of the five elements on the screen, those are probably the most valuable and the toughest to find in the world of IT. Well, I sure am hoping it wasn't too heavy. But I knew if I didn't say it now I'm never going to say it in this whole series, because I've already recorded the rest of the series.

00:12:42

You are going to love this. You're going to love all of these elements coming together to give you the best principles of network design that you've ever seen. Well, good luck. Enjoy the series. I hope this has been informative for you, and I'd like to thank you for viewing.
