Hello and welcome back to I, C and D one interconnecting Cisco Networking devices, Part one This episode 514 Configuring connected routes and villains
00:10
on trend here and I'll be your instructor for this course. Last video went over the hell the router determines where to send a packet. We went through a routing process, step by step,
00:18
the seven Children recovering what the connected routes are and how it's set up. Villain routing the rotors
00:25
so their objectives were going to get some routing commands. We're gonna look at the AARP table hunter router, really get connected routes, and then we're gonna set up a router on a stick. So that's where
00:35
remember, we have a couple of the lands on a switch connected through a trunk port
00:40
to that runner.
00:43
So jump into the pre assessment here. Which source I p will be in the packet from pc to PC one when the packet has reached router to
00:54
so a deposit re read that question sea if you figure it out.
01:00
All right. Remember, it will be PC to the source. I p will be PC to in the destination. I p will be P C one.
01:07
But when it has reached
01:11
router to the source, Mac address will be of that of switch to
01:15
and the destination Mac will be over after two.
01:21
Is that link,
01:23
So we'll have diagram. If you want to take a screenshot of it, throw it off the side. We're gonna reference it. Ah, multiple times here. Just know I have my Kelly vm up the top in 10 110 slash 24
01:36
and the moon to laptop donut 10 12 then off to the right. I have two different v lance off of switch three
01:45
with the surface. And I have a raspberry pi hooked up on set of veal and 50.
01:51
Remember, you have to change on the switch ports. You have to stop them into the right. Right B line. Don't forget that,
01:57
um and then configure the whatever port you have connected to the router it configured out of the trunk port.
02:04
Then we will actually go in,
02:06
and we're gonna configure the eyepiece for the different interfaces on Router three.
02:10
The rest of them are already set for outer one and router to, and I've thrown on the I P addresses for all the different client machines in here as well.
02:19
Remember that the default gateway you're gonna set for these client machines is that of the router interface. Meaning if we take the Cali VM up at the top being 10 11 50 the default gateway would be 10 11.1 being slashed 24. And we're gonna put the 240.1
02:38
as the router. One land connected interface. Not sure what that means here in a minute. If you don't get it,
02:45
we'll jump right in with some of the commands.
02:47
So this is kind of the fundamental commands you're gonna you know? You know, you need to know on the router. Um,
02:53
the show I peer out, that's that's huge as going to show you all of the routes for the different sub nets. So if you know that you're trying to get to a certain network and your outer doesn't know about it and the default or the gateway of last resort isn't so,
03:09
this could be why your pack is not running because there's no route. That router doesn't know how to get there, so it's gonna drop that packet
03:15
show I p AARP What's that's gonna do is
03:20
show you the little table
03:23
of the I P address, the hardware address and where that interface was that it came in on.
03:29
Then you guys should know the show interfaces, interface status, that kind of thing. Then you should know as well how to configure a i p address on interface that will go through that will sign a few of them on the router. Three.
03:43
So what is it round?
03:45
So connected route is gonna be a sub nets that is connected through the interface. So if you look on the picture on the bottom right, you'll see a C and l that is connected and local.
03:57
So do you take 10 that one down 3 to 0 slash 24. That's a connected route that
04:02
will be a metric of zero.
04:06
Static was one will go through in the next episode.
04:11
So a static grout is actually an administrator. Configure out. So let's say you have a faraway sub net that you you know how to get there and you know that. Let's say you need to go out 0010 s so you can statically configure that to say, OK for this subject. Go out This interface
04:30
low local row is gonna be that loop back around for the interface. I P address and routing protocols is the way that they dynamically learned routes. So that way, you're not admit your net engineer doesn't have to go in and configure every single route.
04:44
Ah, you could dynamically learn them in that way, if a link goes down on the routes, that's gonna automatically adjust and send it through a different route.
04:51
Um, it's gonna figure out, you know, you could do load bouncing. So are like I said, there's a table, um, list that I peed a Mac to interface mapping,
05:00
right? So how we could clear that everything do a clear I p AARP and undo the Appy address
05:06
cleared out. Let's say that for some reason, they're having some kind of I p conflicts where maybe your d a. C P. Server got Mr Made its two of mine. They're they're both the signing I, p's and,
05:17
um so you can clear that out. You can use out of the troubleshooting step to see if that I p k keeps coming out of there. You know, if you if it's
05:26
you're seeing that a peace somewhere else in the network. They've seen it there and clear amount. See what's going on.
05:31
Ah, the default is a four hour timeout or 14,400 seconds, since that's how it's labeled in the command.
05:39
So you want to change that? You could do a I p space our space Time out. Space
05:45
200 for 202nd. So is in seconds.
05:48
Um,
05:49
we'll jump right into getting our row as her a road on a stick. So here's what we're gonna route between v. Lance, Right?
05:58
So remember than the we talked about it before were you could use one link for each of the land. Um, you could, you know, a sign and I pee in each V land for that.
06:06
But it's not.
06:09
It's not smart to d'oh. It's, um, no, consume all your reports on your router.
06:14
Take, for example, my 18 40 ones there.
06:17
They only have to fast Ethernet ports.
06:20
Um, without any issue with cards, said I would have, you know, one or two B lands, depending upon when I help links.
06:30
So what we can do is to utilize the v Lance from a kind of switch between the router.
06:33
Um, and that's what we called around on a stick or rose. So as one length for all the lance so we have to do is well, actually create sub interfaces for each re land under the physical interface that is connected. Thio.
06:46
So let's say the on the router fast. Internet 00 is connected to the trunk link on the switch so we can do,
06:55
you know, interface fat season at zero slash 0.10.
07:00
Ah, for all save you intend the 0.10 doesn't actually have to correspond to the villain, but it's just best practice to do that. And then what? You actually get into that sub interface command mode? Do encapsulation debt one q than your villain I d.
07:15
So that that's where you actually assigned villain 10.
07:18
And then you will assign the API address for that villain. I d as well for that interface.
07:26
Ah, for the native villian, you can configure it on the you actually confirmed that on the physical interface.
07:31
Um, or you can configure it in a sub interface with the native command under the, uh, encapsulation command she had the native at the end.
07:42
But we're not gonna worry about the native right now. Extends. We only deal with Dillon. 30 interview and 50 in the native is just defaulted to the line one. So I have gone ahead and set up the switch. Uh, I have gone and
07:56
set up on the Kelly B. M at the top and then the Abou t 11 a bottom. They can both ping their default gateways, but there is no route set up on the routers, So that's all they're routing to.
08:07
So I bring up the party session
08:09
and let's do a
08:13
show. I p
08:15
their face brief. Let's see what we have. So all of them are down.
08:18
So he's going to hear
08:20
Let's go to serial 00 We'll get the I P. Address. Except for all these first here.
08:28
Ah, so seals. They're zero.
08:31
That is gonna be turned up. Wonder Ford a six,
08:35
255 to 5 to five. And what does a slash 30 to come out to
08:41
2 52
08:43
And where we had to do it? No, shut on. Exes wth e rodders come like that
08:48
and we're going to interface known us.
08:52
You're one
08:54
Do I P address
08:58
and one for two,
09:01
2552 for fire 2 to 5 to 52.
09:07
Runa No shot on that.
09:09
And here is where we will start getting into the sub interfaces. So I'm going to festive tonight. We'll do veal in 31st. So serious Less 30.
09:20
About 30 like that and we'll do I p address.
09:26
Okay,
09:28
10 13
09:31
That one. And this is a slash 24.
09:35
So do that.
09:39
If you're if you're running layers. Oh,
09:43
maggot!
09:43
Cancellation that one Q. And then the veal and I d
09:48
Let's go back up now that should work
09:52
knows to an interface phaser 0.50
09:56
missile before veal and 50 doing encapsulation 500.1 q
10:03
50 i p address.
10:07
Tend at one that five. That one slash 24
10:13
run a no shirts.
10:18
Is your zoo that 30?
10:20
No shirt
10:26
you can't
10:28
And remember, If the FAA 00 isn't a shutdown states, it will not work. So we must use because it's a sub interface of F A 00
10:37
So we will run a no shut if it's zero.
10:41
A show i p interface brief
10:46
and we're up it up. So see what we have in the art cash here.
10:52
All right, So I'm gonna go ahead and shoot a ping from my surface laptop here
10:58
just so we can see if we can build on that art. Cash should come in as a 10 15.50. We'll see here.
11:07
All right.
11:09
Right.
11:09
No, 10. 13 50. So there we go.
11:13
And if we pick it back here,
11:16
we should get a positive response.
11:20
Oh, all right.
11:24
So that's how you create a runaround stick. So if I were to, I'm gonna go ahead and
11:30
I will shoot a pink from the surface to the
11:33
resurrect pie. That's from view. And for 32 Reliant 50
11:37
it'll go through, eh? So what it does is it goes up through the switch, hits the router. It goes through that routing process and says, Okay, I have roots for it,
11:46
because if we do a show I p wrote, Now
11:50
you'll see it knows how to row out to the
11:54
37. I heard the three submit and then the 50
11:58
which through this sub interface in the sub interface,
12:03
So it'll go from the one computer gets through to switch to the router and route it and say, OK, I need to go back out to this sub interface
12:11
And what it does is what that encapsulates do not want. Q.
12:13
It's going to say OK, we need to tag this with Reliant 50 centered over that trunk port to switch.
12:20
Where are the trunk? Sees it veal and 50. It knows where to go.
12:26
So as quick,
12:26
How did create the router on a stick?
12:30
Go ahead and minimize the party session here.
12:33
So to recap, we went through some routed commands. We took a look at the I P R table. We looked at the connected routes on the interfaces
12:43
and then finally, at the last, we set up the router on a stick.
12:46
Um,
12:46
please go back through, set it up. Make sure that you have the
12:52
interface is set for the other two routers as well. If you have this hooked up
12:56
because we're just gonna go through the next one of sending static Krauts so we can actually route from the very top to the very bottom
13:05
Quick post assessment here. What is the protocol that maps the eyepiece to Mac to interface. Gave it a few seconds.
13:13
All right. It is the art.
13:16
Her address, resolution, protocol.
13:18
And again, the next episode will get later. Three. Switching and configuring those static route. So we're actually gonna use that? Ah, I'm gonna change that switch three into a layer three switch.
13:28
And we're gonna route between the V lands on that That way doesn't have to travel all the way up to the router. I can just do the switching at the router or switch level.
13:37
And there were configured a static droughts for the R three earlier routers.
13:41
That way, they can route from top to bottom to each each subject.
13:45
As always. If you guys have questions, need help. Feel free to shoot me. Message. Otherwise, thank you for washing this video. You know, afford a senior recipe.
