Cisco CCNA certification proves your professional worth. It tells prospective employers that you can handle the day-to-day work of running a mid- to large-sized Cisco network.

The two-exam CCNA process covers lots of innovative features, which better reflect the skills and knowledge you'll need on the job. Passing both exams is your first step towards higher-level Cisco certification, and trainer Jeremy Cioara has mapped these CCNA training videos to the 640-816 test. This CCNA training is not to be missed.

Here's how one user described Jeremy's training: "By the way, Jeremy Cioara has to be by far one of the BEST Cisco trainers I have ever had the privilege to learn from overall. He not only keeps your attention but his energy is contagious and he provides the information at a level where you grasp it rather easily."

The last day to take the 640-816 exam is Sept. 30, 2013. After that date, the only ICND2 exam available will be 200-101. CBT Nuggets has a training course for the 200-101 exam here.

Review: Rebuilding the Small Office Network, Part 2

00:00:00

With the LAN equipment completed we can now move into our routed connections. As we start rebuilding the small office network part two. Now what I plan on doing here is the same thing that we did in the previous video, which is walking through the concepts as we do the configurations. And we are going to

00:00:17

be focusing on routers. There is a bit more to the router world than the switch world so what I plan on doing is breaking this into two separate videos, and that way we can take our time and walk through these router configurations without feeling rushed. So

00:00:31

let's move back to the topology. I've added a little bit more information. What I've done here is labeled each one of the router interfaces that are going to be connecting our network together. So that way at least we know what we're configuring. You can see that

00:00:43

we have three routers. They're in our halos here. Router one, two, and three. One being our internet connection. Now in this video and these, setting up the small office network, I'm going to leave the internet connection a mystery for now. The reason why is

00:00:57

if you went through the CCENT series, we set up NAT using the SDM, the graphic interface. Well in this series we're going to be setting up NAT using the command line interface. It's much more fun. But I'm going leave that to when we get to the official NAT

00:01:13

section. So for now the internet connection will be mysterious. Over here we've got router one connected to the LAN and this all of this area over here, represents the 192.168.1 subnet. So all of that information will start with 192.168.1.x. You can see that I've got our switch IP address already added in. And while

00:01:35

we haven't configured them I decided to put the IP addresses on the diagram so we knew what we'd be getting into as we walked through the configuration. We have a WAN link that's going to be connecting router two and router three and router three will have a LAN connection over here that will allow us to do some tests from our headquarters which is this zone. Over to our branch office on the other

00:01:55

side. So in the beginning let's start off by wiping out our configurations on each one of these routers. Now I want to make sure that you guys know how I'm set up here. I have an access server and what that is and I'll explain a little bit more about this later on in the series, but it is a box that has cables run to the console port of every single one of these devices. That way I don't have to run to the other room and

00:02:21

move my console cable every single time I want to move around It's a pretty awesome device that allows me to telnet into one box and then it's known as a reverse telnet. I reversed telnet into the console connection of all the other routers. So when you

00:02:34

see me go into the management console I don't want you to be confused. All I have going on here is just a access or reversed telnet connection to each one of the routers. So let's start off by wiping out the configs. I'm going to go to router one. Do not answer, you'll certainly perish. I actually don't even remember setting

00:02:54

that up. So I'm going to do a write erase. Erasing the nvram file system. Looks like we got a little duplex mismatch action there to that. We'll have to fix when we reload it so I'll type in reload. Enter, enter. So we'll get that router rebooting. I'm going to do a control

00:03:14

shift six x, which you might remember suspends telnet sessions. It's the same thing on this access server and then I'm going to go over to router two. I have little aliases set up that if I just type the number, it pops me over to the router. So that way you understand how I'm hopping between all these

00:03:28

devices. Get into privileged mode. All the passwords are CISCO so I'll type in erase startup config. Same thing as write erase. While that's doing it and you'll see how I increase my speed here. Get in erase, let's just do a write erase on that guy. Pause, go back to router two. See the speed reload,

00:03:49

router three. Oh, we're still hanging there. Waiting for the prompt to come back. There we go. Reload. Alright so, with that we now have wiped out the configs on all three of those routers in the same way that we wiped out the configuration on the switch. Now all three of those are rebooting and that's the

00:04:07

benefit of using that access server; is if you want to, you can actually watch them reboot unlike a telnet session because I'm plugged in from my access server; from this router right here to the console port. So we can watch reloads and things like that. Now I

00:04:21

don't plan on watching all these routers reload. We'll scroll back and see in the history at least one of them so we can review that. But once, I'm going to pause the video, once we come back we'll walk through the security on each one of these routers, and I'll show you how to increase your speed in configuring multiple routers there as well.

00:04:38

Alright, I've been watching the routers and it looks like router two is officially rebooted so let's go ahead and check off our wiping out the configurations. And we'll start off with router two, the other two are still booting right now. And get the passwords

00:04:51

and banner message set up. So pop up our configuration, hop over to router two. It's asking us if we would like to enter the initial config dialog since it has no configurations and we'll say no. Press return to get started. We'll wait for a second as it

00:05:05

spews a bunch of console messages onto our screen just saying everything is now ready. You don't have to worry any time you see a bunch of stuff like that, just hit the enter key. So I'm now sitting on the router. Just like the switch, move in to privileged mode.

00:05:18

First thing I'll do is block the privileged mode. I should say secure it. So I'll type in enable, secret, and the password will be CISCO. Just like the switch, line vty 0 4 require logins and the password is CISCO. Now, just so you know, this command while

00:05:36

I'm in the habit of typing it, it's on vty lines by default. So when you pull a router out of the box it requires logins and that's great because if you didn't know that and you set up an IP address on your router somebody could secretly telnet in before you had a chance to get in there and set passwords and so on. So

00:05:54

logins are required on telnet ports by default. But they're not required on the console port and the aux port. So I'll type in login there, password CISCO. Not cisci; CISCO. And the aux port which a switch does not have is used to connect to modem but you have to be careful because if you connect to the console port with the console cable and find out they have a password; you can actually move your cable right over to the aux port and it works identically to the console port. So you'll be able to hop right

00:06:29

in on the auxiliary port there as well. So what was I doing? Password on the auxport of CISCO. Good. So we've got the passwords configured now let's set up our logon banner. So I'll do banner motd and we'll go ahead and use the pound symbol on this guy. I like the asterix. Please don't log in. We'll be courteous

00:06:56

this time. Throw some asterix on there and end with that pound symbol. That ends our longon banner. Now that's secured. So we've got all the passwords set, I'm just running through my mind. Enable secret, enable password or well, we're just using the enable secret here. The console port the vty

00:07:15

port, the auxiliary port; we're all locked down. Now one thing we didn't do on the switch that I would like to do on my router is encript everything. Because by default, when you set up your router only the enable secret is encrypted. I'm doing a show running config and I can see

00:07:30

I've got gibberish for that but if I scroll down to the bottom here I can see that my console port, auxiliary port, and the vty lines all have CISCO in clear text. So I'm going to go into global config mode and type in service password encryption. Now what that will do is encrypt any clear text

00:07:51

password that's on my router now and in the future. So that service password encryption is saved in the running config and if later on I add different passwords it will encrypt them as well. Now, do keep in mind that the service password encryption is never as secure as the enable secret. There are actually websites

00:08:09

out there that you can go to and paste this in there if you can get that and it will unencrypt it for you. That's pretty dangerous. So the point of that kind of encryption is just to keep the clear site. You know if somebody was looking over your shoulder

00:08:24

it's a lot tougher to remember that than it is the password CISCO. So we're good to go on this router, and what I want to do is give myself a shortcut for the other routers. Let me just make sure that, oh, I still got a few more things. I'm going to do the

00:08:39

name and work environment. Get my work environment set up just like I did on the switch. Now this is router two, so we'll get in and do the host name R2. Name is done. We'll go under line console zero. Logging synchronous. And line vty zero four also logging syncronous. Just hitting the up arrow on my keyword to

00:08:59

recall those commands. That again that allows the messages to come through the console port without interrupting what I'm typing. I'll do a no IP domain look up from global configuration mode, which means if I'm in priveliged mode and type something invalid it won't hang there for sixty seconds or thirty seconds. One thing I forgot under the console

00:09:20

port is for this series in this lab environment I'm going to turn off the exact time out which allows this console port not to kick me off after such and such amount of idle time. So I'll save my configuration. We've got the name and work environment configured on this router. Now I'm ready to save myself

00:09:43

some time on these other routers. The way I'm going to do that is I'm going to back up my configuration by using the the same method I used when I was backing up the switch, just doing a show run, come back here to where I first typed that. Go from the exclamation

00:09:58

point and go "shoomp" all the way down. It's alt C see in tera terms. Backwards from the control C that we're used to. I'll open up notepad bring it in here and paste. Now, what I'm going to do is go through this running configuration and remove things that I know the other routers don't have. For instance, versions 12.4. I don't know that the other routers have that version of IOS.

00:10:25

A host name; I'll just kind of wipe that out because I'm going to type that in for each router. Enable secret that's going to be the same. Same, same, same, you know, oh, voice card. I know the other routers don't have voice cards because they're not voice routers.

00:10:38

All of the interfaces I'm going to remove because I have different interfaces on all my routers. Now that one would be up to you if you were configuring a bunch of routers in your environment that had all the same interfaces then keep the interfaces in there. Other routers don't have voice ports probably

00:10:54

don't even have a control plane. Log on banner, that's good. Got that. Console port. They've all got that. Auxport, they don't all have this line 130. That's specific to the router than I'm working on. You can see my vty lines, webvpn all that kind of thing, other routers don't have. So what I'm doing

00:11:14

is I'm just going through all of this configuration and kind of cleaning it up. See what I mean, to where it's just a base configuration. And now what I can do is modify it to work for these other routers. I'm going to, I've got router two done so let's do R1. And remember our objectives? They were to what about the configs, done. Password and banner, name and work environment. Well

00:11:36

now I have a great configuration that can do that for both routers. So I'll start with router one. I'll do a select all. Copy. Pop-up here. Control shift six X back to my access server and down to router one. Now router one's asking me, do I want to enter initial

00:11:54

config, and while I'm doing that I'm going to hop over to router three because it hangs there for a little while, and answer no on that guy as well. See how you can start moving pretty quick. And that way I can get both of them kind of working on that processing while it's waiting for that press return to get started. So we'll hit enter.

00:12:12

Let our messages slide through. There we are, user mode. Now check this out. I'm going to go in to global config, don't paste it into privileged mode because these are all global config commands. I've already copied it to my clip board so in tera term all I need to do to paste is click my right mouse button, click click.

00:12:30

Isn't that great? Look at that, done. What I've done is now configured router one with all the same settings that I used for route all I missed one of them. This one doesn't have the resource policy command. Different versions of the IOS will do different things but that's okay it just gives you an invalid thing. So with that

00:12:48

I can now save my config on router one; hop over to router three which is happily sitting on its users mode prompt. Come back here. There's only one thing I'm going to change and that is my host name. Control A, control C, copy that to my clip board. Go into global config and right click, paste. So I put that in there

00:13:11

wham, just like that we now have steps one through three done on all three routers by using that shortcut and I'll save my configuration. Now we can move into the interfaces themselves. We need to assign the IP addresses. Get the speed duplex and descriptions assigned so that we can have a good idea of what these things connect to.

00:13:31

I'd like to go in order on these ones since they're all booted and everything is configured. So let's start off on router one right over here. So I've got router one. My favorite all time CISCO command is show IP interface brief where I can see what interfaces I have. I noticed this has ethernet zero zero, zero

00:13:48

one and serial zero slash zero. Now I'm looking at the network diagram and it looks like ethernet zero zero is plugged into fast ethernet zero slash one. So let's configure that one. Go into global config mode and I'm going to show you a short cut that I, this is by the way bonus information but I do this on every CISCO router that I work on. I love show

00:14:11

IP interface brief so much. I type in alias exec s show I interface brief. On every router I work on. So that way I can just hit S and get a quick status report on all the interfaces on my router. Alias exec is how you make an alias for the exec mode, meaning the privileged mode. So I'm into

00:14:31

global config, let's get under ethernet zero slash zero. I'm first going to do a no shut down and then I'll do IP address 192.168.1.1. There we go. So we've got that IP address configured now on the interface and we configured the switch in the last section so let's make sure that we're able to ping from ooh; let's stop right there. I'm going to ping from the router to the switch but before

00:14:58

I do I want to hit this duplex mismatch. Now if you haven't worked on CISCO routers very long this is one of those guaranteed messages you're going to get at some point in your CISCO career. This is something that's detected by CDP, CDP discovers it, and says there's a duplex mismatch between your interface, ethernet zero slash zero which is not full duplex with CBT switch two fast ethernet zero one which is full duplex. That's the way to read these because

00:15:25

if you don't read them that way they sound confusing. It says discovered on that not full duplex with this is full duplex. So in essence we know, because we did it in the last video that we hard coded CBT switch two to be full duplex on fast ethernet zero one. So

00:15:40

while we're under this interface I'm going to type in duplex full, enter. Now we are hard coded here as well. Now since this is an ethernet zero slash zero there is no speed command you can see nothing that starts with SP because there's only ten megs per second on ethernet zero zero interfaces. Alright, now let's

00:16:00

exit back out. We've got our duplex hard coded. You know what before I do that. Let's type in description link to CBT SWITCH2. There we go. Now we've got the descriptions speed, duplex IP address done. Let's make sure we can ping 192.168.1.10, which is our switch. And no. Oh wait, I just remembered. I did something.

00:16:34

I didn't tell you guys but I did something. I guess now is a good time to tell you. No it's a horrible time to tell you but I'm going to tell you now anyway. What I did was, remember when we were doing the previous video and I set up CBT Switch 2? Remember how I set up the VLAN 1 interface with the IP address? Let me do a show IP interface brief over here on the switch because I have to expose well, confess here what I've done. I am going to be using VLAN

00:17:02

50 for everything. Now I know we haven't talked about VLANs that's why I said it's a horrible time to explain this, but what I've done is I've assigned this VLAN 50 which is a VLAN that shoots through all of the rooms in this building that I'm talking to in right now. The reason I did that is because if I left it

00:17:21

on VLAN 1 I would have to run into the other room anytime I wanted to move things around, move a cable, things like that. But by assigning everything to VLAN 50 which is reachable from any room in this building, that means that I don't have to run into the other rooms. Now come back to the problem. That's

00:17:39

again my five second view of VLANs before we fully describe them. The reason this is not working correctly is I forgot, it just hit me; to assign all of the interfaces to that VLAN including the one that I'm working on now. So I'm going to give you a sneak preview of a command you'll do many times when we get into the VLAN section. Type in interface range fast ethernet zero slash

00:18:05

one through twenty four. Well, let's do one through one through twenty. I think those last four are used for something. I'm going to type switch port access VLAN 50, enter. What that does, and again, the ten thousand foot view is put all twenty of those interfaces into this VLAN. So now you

00:18:28

can see that I have the IP address assigned to the switch on VLAN 50. All the interfaces are in VLAN 50 which means that fast ethernet zero slash one right here is now on VLAN 50. Let me see if I can give you a better description here. This is in VLAN 50, this IP address is on VLAN 50. So now this router should be able to go through that interface to reach this IP address. If that doesn't make sense forgive me but

00:18:53

we will fully describe that when we get into VLANs later on. So now that I've done that magic let me jump back over to my router 1 that I was working on and try that ping command again. If I could tell you that, okay, good. I was going to say if I could tell you the pain

00:19:12

I feel in my heart right now. It's good. The reason sometimes it takes a moment for the pings to go through is because we have the ARP request. We also had the VLAN switcharoo that I just did, it takes some time to process that. So now when I'm doing it I'm getting five successful pings

00:19:28

each and every time. So we have connectivity now between router 1 and our CBT switch. I need to put a good name on that guy. So let's hop over to router 2. Here we are. Show IP interface brief. And meanwhile let's go into global config mode. Alias exec s and copy paste.

00:19:51

So I am now going to go into my fast ethernet zero slash zero port. And configure it with the IP address 192.168 one dot one; I believe it was two, let me just verify that. 1.2 right there. Good to go. 255.255.255.0. Enter no shut down. You don't want to forget that one.

00:20:17

So we now have fast ethernet zero zero up. I'll just do a parallel jump. CISCO allows you to jump modes without exiting back to global config so I'll just go straight into serial zero slash one slash zero. Which reminds me, I need to change that label right there.

00:20:38

Router 2 is the newest router that I have it's a 2811. And let me just see if I can find that label real quick, there we go, serial zero slash one slash zero. It uses the newer syntax for the ports and if you haven't seen these before this is module zero on the switch port or, sorry, I should say Vic card zero and then port zero.

00:21:03

The way this this router looks I should say Wic card. Is we have this router right here, it's got two built in ethernet interfaces a console port and so on. And it's got this big module over here like this. And that module allows me to slide in this big blade if I could zoom out on that it would be this big blade right here that allows you to have up to two little Wic cards that you can put inside of there which can support up to two ports per Wic card. So when I'm

00:21:34

doing serial zero slash one slash zero I'm saying module zero Wic card one. This is Wic card zero and then port zero on the Wic card. Because all the numbering in CISCO begins from zero. So that's what I'm looking at when I'm typing in that syntax right there. And now we get it

00:21:54

correct it on our network diagram. So let's jump back there. I'm going to type in IP address and this one was 192.168.2.1. I'm going to double check that in a moment and I'll do a no shut down. Good. So what we've got, if I jump back and hit S now that I've got my shortcuts

00:22:12

and plays is I have this fast ethernet zero zero interface which is currently up, line protocol up, so we're communicating there and let's just make sure we can ping to our LAN that's our switch IP address. Come on switch, where are you at? There you go. And let's ping the

00:22:29

other router, 192.168.1.1. There we go. So we have successful pings going to the switch, to the router, our LAN connection is working well. Now if you look at our WAN connection, let me hit the S key again, you notice that serial zero slash one slash zero is down and the line protocol is down.

00:22:50

Now, remember this is the physical and this is the data link. So something right now is physically wrong with that line and I think I know what it is. In this lab environment we have a crossover serial connection. You always use crossover serials because you don't want to pay for a full T1 line to connect two routers in the same room with you. So you do, it's just a cross between

00:23:11

them. But remember on every serial connection there is one side of the cable that is considered a DCE and the other side is considered a DTE end of the connection. Now in the typical quote unquote real world the DCE always connects to the service provider. So that'll be are link to our CSU DSU

00:23:33

or whatever we're connecting to the service provider with because this side sets the clocking or the speed of our connection. The DTE data terminal equipment always connects to us, our end of the router. But in a lab environment we are the service provider and we are the DTE so whatever end of this cable is plugged in, that's the DCE; will have to set the clocking for the line.

00:23:59

Now without physically looking at the cable there is a command that you can type in. It is show controllers serial and I'll look at zero slash one slash zero. Enter. And I can see that this side, great. This side has the DCE end of the cable and it has a clock rate that is already set on that. Now this is in bits

00:24:24

per second so that is I believe, if I got all my zeros in order there, that's two mega bits per second that it's setting the clock to. So this side is the DCE in the clockings so why is it down? Well the reason why is because the other side is shut down. So since

00:24:40

the other side is completely terminated it's not getting any electrical signal on this interface at all. So we need to go configure router 3 before we can power this one on. So, let's save our config there. And did I do that on one? I'll do it now, just in

00:24:56

case. And then let's hop over to router 3. So I'm on router 3, show IP interface brief, global config mode, alias exec. This is probably something I could have done in my little script. That's for all of you Canadians out there. So we've got show IP interface brief that's now abbreviated and I'm going to get under serial zero slash zero since that one is on my mind let's get that one first.

00:25:19

And I'll do an IP address. This one is 192.168.2 dot.... I believe it's two so we'll check; yep. Router 3, 2.2 and just while we've got it up here this is ethernet zero zero and that is 3.1. So I'm going to do 2.2 no shutdown. So let's watch some of those status messages just to

00:25:43

see what happens there. I'll do, yep, you can see right there interface changed to up and line protocol changed to up. So that immediately tells me, physical layer is good and the data link layer is good. Let's take a momentary pause and hop back over to router 2 real quick. Let's just do that show IP interface brief there. You see why I love this command so much? It's awesome! If I could have my one command that's all I could type, this would be it. And I can see up and up, it's now gone up on router 2 as well because it now sees router 3 as online. So while we're back on router 3 I'll get back under ethernet zero slash zero, IP address 192.168.3.1... 255.255.255.0. And I will type in a bonus command. This is a hint for any of you that

00:26:34

would like to create a lab environment. This interface as of right now is not connected to anything. This, I'm going to actually simulate this PC by using a loop back address. I'll show you how we're going to do that later on, but if you set up a lab environment it's a complete waste to attach a computer to the other end and use up a switch and all that just to have it sitting there to ping it. So what a lot of people will do is simulate

00:27:01

a LAN connection by turning off what's known as the keep alives on an ethernet interface. I'm going to type in no keep alive and then do a no shut down. What that does is tell the ethernet interface don't look at yourself. I'm trying to think of a good way to say that

00:27:20

Don't even think about checking to see if you're really there. Don't send out any keep alive messages to see if something is alive on the other end so that way even though it doesn't have a cable plugged in, it's always going to show up and up which gives us great virtual connection that we can test for pinging and we can, you know, always show that as up. Now if you

00:27:42

have bonus equipment and you want to connect a switch and another PC over there, great, feel free to do it. But this is a great way to simulate as if stuff was actually there. So we've got the, identity we've identified all the interface, show IP interface brief, the IP address, speed and duplex. I've got to admit I kinda

00:28:03

skimped on the descriptions but we're okay with that. We've got an accurate network diagram and as long as you have an accurate network diagram sitting in front of you that's just great. You don't need descriptions because you can just look at the picture.

00:28:18

Now, I'd like to stop this video right there because that gives us the core of the router set up and I'd like to have some extra time as we get into routing, talking about the default internet route. We'll get that internet interface up and Rip routing because

00:28:30

we are going to talk a lot about routing protocols and how Rip is the worst routing protocol in the world but that's later on in the series. At least Rip will lay the foundation of all the concepts. So for now I hope this has been informative for you and I'd like to thank you for viewing.
