Hello. Welcome back to I seen. Do you want interconnecting Cisco networking devices? Part one?
00:05
This. It was a 5 to 4 review to verification in trouble. Shoot.
00:10
I have trained ear when I will be instructive for this course was doing When are you gonna figure V two
00:15
in this episode of purposely messed up configuration at one of the devices and we're gonna try and see if we can figure out what is wrong.
00:25
We're learning objectives day. We're gonna verify our configuration, and we're going to troubleshoot at the same time.
00:31
Brings us into the pre assessment here. What is the administrative distance for a connected route?
00:39
All right, it is zero or than 90 is e I g European one tennis. Oh, SPF and 1 20 is rip.
00:48
All right. And here we see that we have the normal, uh,
00:53
lab that we've been using. We have switched three. That's a layer three Swiss still,
00:57
um, we have our peas in there,
01:00
so everything's still set up from the last couple of videos, so nothing has changed.
01:07
That's a very fine troubleshoot. Remember the showrunner config? You want to look for that router rip section? You show I P protocols will straight here in a minute.
01:17
Um,
01:19
and we're gonna do
01:21
is
01:23
sh i p routes rip. Remember what I showed you that one earlier? Is the show appear out? Show you all of them. And then you can specify rip only enabled routes
01:30
in the show. I p ripped database will actually show you that when I was a really cool one to dio too.
01:36
So they bring in my party session,
01:38
we'll just go through each one his commands.
01:42
So, Ryan config.
01:45
Uh, I'm just gonna do a begin at Router Rip
01:49
just to show you what we would have figured here. Cue to stop.
01:53
So see what we got.
01:55
We have version. Too. Good. We have the passive interface to fault. No passive interface on the serial 00
02:02
which is good. We have the network command maximum paths. Default information originates. No auto summary,
02:08
so they know. Looks good. So let's go ahead and take a look at the rest. Here. Show I P protocols.
02:16
We'll see what we can to get.
02:20
All right.
02:22
So running protocols rip
02:24
sending updates every 30 seconds next to an 18 seconds.
02:30
See what else we can find here we're routing for networks tender zero, then these are all of our passive interfaces.
02:37
And our gateway is 10 1 for two.
02:43
All right,
02:47
so if we go ahead and do I want to show you nor come in here, I showed you show CDP neighbors.
02:54
This shows the other devices that are
02:58
connected to it. The Narcisco enabled devices.
03:01
We'll go through it in a little less if you wanna shoot. That's very useful for a quick okay on a router. Three is on serial zeros. Okay, so that's good, because that one's not a passive interface.
03:14
And I realize now my host names are not the same.
03:17
So I apologize for that. That sucks.
03:21
Okay,
03:23
so we'll go ahead and just try and paying through the network here.
03:27
Ah, see what we can find. 10
03:30
one,
03:31
man. I can't.
03:34
I don't want for two.
03:36
Okay, we can ping there. Let's do the other side. Going down to 10. 146
03:45
Ah, Okay. That's not good.
03:53
Let's try a little closer than so we can paying Router three.
03:58
Well, we can't paying the other set of router three. So let's try going out to the other side here was to a king to the fast eastern. It over after three. So 10 1
04:09
4.9.
04:14
Okay, that's not good. I can't get down either.
04:19
Let's go ahead. I'm gonna bring up the rip database here. Show rip
04:26
that obeys
04:28
here.
04:29
No show, I p rip. Sorry.
04:35
All right, so
04:39
that's fine. We're
04:42
they're connected.
04:45
So this is what we're sending out.
04:47
Um,
04:49
this is the rib database, so let's do a show I p Route rip. See what?
04:58
Well, that's not good.
05:01
Show I P routes.
05:05
Okay, so
05:10
our next link is Rod or three. So let's go plug into that, because for some reason, we're not getting any routes from it.
05:15
Um,
05:18
I'm gonna go ahead and plug in a router three here and see if we can find.
05:34
All right, sir. On runner. Three months. Do a show. Run.
05:39
Begin at Router Rip.
05:45
Ah, version one. Uh,
05:47
hey,
05:50
so let's do a show.
05:55
Maybe protocols here. See what you find.
06:00
All right.
06:06
30 seconds for it.
06:09
Mmm.
06:11
Okay, here's again. We're seeing version one like some past four routing for
06:17
10 darts.
06:19
Here's a routing sources,
06:23
which makes sense here.
06:29
These would be. And this would be rather one has to be rather to this would be switched. Three.
06:34
So you could do is show CP neighbors. Here
06:40
we see all three devices.
06:43
Okay,
06:45
show I p routes.
06:50
We have no rip connected ones. Let's do a show I p
06:58
rip database.
07:02
Okay,
07:03
So what's going? And try and change the version number here, I guess.
07:11
Let's see, we can do up there
07:14
because we're What is the version? D'oh version one does not support. And what
07:18
realism?
07:19
Hopefully you got that
07:21
version two does sport bosom.
07:26
It's between hand again.
07:29
So
07:30
a rip database. I see.
07:33
Hopefully it's a scan this page for a second. See, if you see something else that it would be causing a problem.
07:42
So look at the pew dresses here and let me do a and then look at
07:48
what they should be on the
07:51
lab diagram.
07:55
All right? Hopefully you figure this one out. This should not be there.
08:00
Ah,
08:01
something to go ahead was configured that real quick face F a 00
08:07
It's gotta be 10 1
08:11
and a 14.9
08:15
approaching five dots
08:18
to fit two for slash 30.
08:20
Doing and
08:24
show I P interface brief,
08:28
right at nine.
08:31
Let's see if we can ping the other side of that link now
08:35
on, and
08:37
Okay, well, you're being their side of the link.
08:39
Okay? We'll see if we can ping down to rode her too. Then
08:45
10 14 That's five
08:48
were successful.
08:50
Okay, let's try and do a show I p route now.
08:56
Okay, There we go. Now we got our
08:58
that 1235
09:05
Their thirties in here. Okay,
09:07
so it looks like we should be working again. I'm gonna go ahead and plug in a rather one and see what we can paint.
09:13
All right, so we are back in rather one. Let's see, we couldn't ping the far side of the road or three. So it's going ping one, that
09:22
for the six. And we have success this time
09:26
for about nine success. Okay, I'll start paying some post Machine's 10 1
09:33
3 50
09:37
Find out. 50
09:39
and to top 50.
09:41
So we can ping every other so DNA. So we're going to go. We have trouble shot. That's a router in the grip configuration.
09:52
So we look at the recap here we went through we verified our rip configuration out Router one. And then we trouble shot the room configuration on Router three. We looked at the version number. We looked at the i p addresses
10:07
because one they didn't match the network diagram, but to the network command
10:13
WAAS set up for that. So it was actually advertising that incorrect i p address.
10:22
So remember your show. I p protocols show I p rip database. Um,
10:28
show run if you can use it on the exam.
10:33
So it's going to the post system here. What is the default number of paths? Rip will load balance over for a sub net. Something. What? That again? Remember the maximum paths command that we used? What is the default number for that?
10:48
But it is for
10:50
and the next lesson were actually going to look at D H. P on a Cisco router. We're gonna look at getting
10:56
ah, how to set up a helper address. So that way for ins packets properly,
11:01
we're gonna look at how DCP works. We're gonna look at how to actually set up a Cisco router as a d a c P server.
11:09
As always, if you guys have questions need help. Feel free to shoot me. Message. Otherwise, thank you for washing this lesson. That look forward to seeing your estimate.
