Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:00,480 --> 00:00:07,180
In this practical lap we'll take a look to this 30 growling configuration together.
2
00:00:07,370 --> 00:00:15,030
We have four steps to configure for these lab guys in the first step
3
00:00:18,450 --> 00:00:29,830
Levy saying as to configure geek 0 0 interface of all or others with proper IP address compatible with
4
00:00:30,130 --> 00:00:31,950
their names.
5
00:00:33,240 --> 00:00:43,550
So we need to find the compatible IP address for the kids 0 0 interface and that should be compatible
6
00:00:43,550 --> 00:00:47,140
with the names of the others too.
7
00:00:47,190 --> 00:00:57,010
Also in the second step lap saves us to configure geek 0 1 and 2 interfaces of all rather thus showing
8
00:00:57,010 --> 00:01:05,650
the figure and in the third that we are going to configure static routing and provide full connectivity
9
00:01:05,650 --> 00:01:15,850
between all networking devices as is shown in the figure and in the first step we need to run Shaw IP
10
00:01:15,850 --> 00:01:20,080
protocols and show IP rad commands and we need to check it out put
11
00:01:22,660 --> 00:01:31,780
Okay let's go let's talk something about the topology to we have four pieces.
12
00:01:31,770 --> 00:01:35,410
P.S. 1 3 am 1 2 3 and 4.
13
00:01:35,550 --> 00:01:38,150
We have 4 Switch switch.
14
00:01:38,150 --> 00:01:40,220
1 2 3 4.
15
00:01:40,260 --> 00:01:46,050
And we have 4 Rather's rather 1 2 3 and 4.
16
00:01:46,170 --> 00:01:55,990
We have different networks as you can see that we have time for the 1 eleven network four here.
17
00:01:57,780 --> 00:02:05,250
32 network four here for the 4 network 4 here and 2 in it to network 4.
18
00:02:05,440 --> 00:02:18,720
Here and we have different networks between the Rather's tools so we have them for the 1 12th network
19
00:02:18,720 --> 00:02:22,340
for here between rather 1 and 2.
20
00:02:22,460 --> 00:02:34,630
We have 13 we have 24 and we have 34 between rather three and rather four as you can see that in the
21
00:02:35,410 --> 00:02:36,040
picture
22
00:02:40,050 --> 00:02:48,810
we have the IP addresses or this switch and this subnet mask also.
23
00:02:48,840 --> 00:02:50,250
So what that does mean
24
00:02:53,300 --> 00:02:56,860
that means that we can derive something huh.
25
00:02:56,930 --> 00:02:57,410
I think
26
00:03:01,810 --> 00:03:08,960
could we define the network ideas for here using this information.
27
00:03:09,020 --> 00:03:09,800
I think yes
28
00:03:12,960 --> 00:03:27,000
10 for the one eleven five slash 30 slash 24 means we have a network idea of eleven that 0 4 here
29
00:03:30,570 --> 00:03:47,230
also to tune it to the 0 and 40 for that 0 and 2 and 3 that sewer for the portion of this network so
30
00:03:47,230 --> 00:04:00,440
what that is mean if I have a network idea of eleven that zero slash 24 that means I can use this IP
31
00:04:00,440 --> 00:04:02,570
range for this network
32
00:04:06,960 --> 00:04:10,270
run to
33
00:04:13,300 --> 00:04:14,790
two hundred and fifty four right
34
00:04:17,600 --> 00:04:31,900
but because of questions saying ask that all routers all routers this 0 0 interface should have a compatible
35
00:04:32,170 --> 00:04:34,210
IP address with their names
36
00:04:36,970 --> 00:04:51,800
I need to assign the eleven that one IP address for Dick 0 0 because this is rather what I need to assign
37
00:04:51,800 --> 00:05:03,800
the thirty three the three four here because this is rather three I'm just changing the last octet as
38
00:05:03,800 --> 00:05:04,730
you can see that
39
00:05:08,530 --> 00:05:19,930
I need to use to and is who the two and folded up four for the four that for four here and please pay
40
00:05:19,930 --> 00:05:29,710
attention that these IP addresses that I have given to the geek 0 0 ports should be configured as the
41
00:05:29,710 --> 00:05:42,610
default gate they on our PCs gateway of this P.C. should be this IP address right.
42
00:05:42,860 --> 00:05:53,400
All right let's go and configure the key 0 0 interfaces as shown in there figure I'm going to configure
43
00:05:54,450 --> 00:06:02,430
a lemon that one for rather one I'm going to configure thirty three that three four rather three forty
44
00:06:02,420 --> 00:06:13,840
the four that for four rather four and twenty two that two for rather two and let's go Packet Tracer
45
00:06:13,840 --> 00:06:14,350
time
46
00:06:20,330 --> 00:06:31,300
here is my topology that I draw in packet sir and I'm going to configure to geek 0 0 interfaces of the
47
00:06:31,720 --> 00:06:36,360
writers.
48
00:06:36,530 --> 00:06:50,200
Let's go I mean around the ranch and I'm getting into the enablement from now on beginning just from
49
00:06:51,790 --> 00:07:00,650
now I'm not going gonna explain that how I go into the enablement why I joined to the config more because
50
00:07:01,880 --> 00:07:07,340
I talked about a lot of times what these comments are doing.
51
00:07:08,390 --> 00:07:18,830
You can check the previous lapse and learn about them also but from here beginning from here I'm not
52
00:07:18,890 --> 00:07:21,390
gonna tell you that.
53
00:07:21,600 --> 00:07:23,010
Hey guys.
54
00:07:23,020 --> 00:07:34,070
Enable command makes us moving from user mode to privileged exact month all right.
55
00:07:34,090 --> 00:07:35,800
Because you know it anymore.
56
00:07:36,440 --> 00:07:51,130
Okay let's get into the conflict mode and let's say that interface geek 0 0 and I'm going to give the
57
00:07:51,130 --> 00:07:56,990
IP address of 10 41
58
00:07:59,520 --> 00:08:08,280
11 and one for rather one but well I forgot it here.
59
00:08:08,820 --> 00:08:11,750
I just warns me that that's an incomplete comment.
60
00:08:11,800 --> 00:08:18,200
I guess is right because I didn't give the summit mask so I'm giving my subnet next to
61
00:08:21,210 --> 00:08:28,360
Celeste to any 4 which means to verify if you've ever to provide zero enter.
62
00:08:28,700 --> 00:08:37,950
And please don't forget to say no shot brother 1 is OK.
63
00:08:38,180 --> 00:08:40,760
No I'm going to configure rather to
64
00:08:44,450 --> 00:08:52,040
see I enable config interface.
65
00:08:52,100 --> 00:09:03,710
0 0 0 IP address turn for the 1 2 an ID 2 that 2 2 5 5 2 5 5 2 5 5.
66
00:09:04,770 --> 00:09:09,110
0 and no shirt.
67
00:09:09,120 --> 00:09:13,950
Pretty cool.
68
00:09:14,060 --> 00:09:21,570
It's time to take a look to the rather 3 2 Seelye
69
00:09:24,810 --> 00:09:33,790
in maybe now in a V enable enable county in the first week 0 0.
70
00:09:36,100 --> 00:09:47,330
IP address 10 41 30 two that thirty three that three and 2 5 2 5 2 4 5 0.
71
00:09:49,150 --> 00:09:52,870
And no shot
72
00:10:01,560 --> 00:10:02,980
I'm in the rather 4.
73
00:10:03,150 --> 00:10:03,750
Lastly
74
00:10:14,160 --> 00:10:15,780
and no show.
75
00:10:19,170 --> 00:10:20,640
It's okay.
76
00:10:20,640 --> 00:10:22,680
That's pretty cool.
77
00:10:23,070 --> 00:10:25,060
And I comb for your
78
00:10:27,830 --> 00:10:36,470
all my dick 0 0 in the face of all others with proper IP address and they are compatible with their
79
00:10:37,130 --> 00:10:39,990
names Whoa.
80
00:10:40,070 --> 00:10:40,940
That's great.
81
00:10:40,940 --> 00:10:48,010
The first action was taken and let's get into the second step.
82
00:10:49,200 --> 00:11:00,020
In the second step we need to configure geek 0 1 and 0 2 in the faces of Rather's as shown in the figure.
83
00:11:01,230 --> 00:11:12,800
But what we see in the figure here just you can see the network I.D. for example the network idea of.
84
00:11:12,800 --> 00:11:14,220
Here is
85
00:11:17,830 --> 00:11:23,650
10 for the 1 12th 0 and slash 24.
86
00:11:23,950 --> 00:11:32,100
But with that format something is riding on the interfacing interfaces.
87
00:11:32,110 --> 00:11:39,260
There are some labels that one means that news
88
00:11:44,450 --> 00:11:48,950
that one for this interface.
89
00:11:49,180 --> 00:12:07,400
The last octet will be one that to me is use for the one 2 with that 2 for this interface.
90
00:12:07,440 --> 00:12:17,370
So now it's time to configure these interfaces on all routers as shown in the figure.
91
00:12:17,370 --> 00:12:24,900
Please keep in mind that the last of that will be valid for either 1 2 4 rather 2 3 4 rather 3 and 4
92
00:12:25,260 --> 00:12:27,270
4 rather 4
93
00:12:30,240 --> 00:12:34,520
Packet Tracer time.
94
00:12:35,910 --> 00:12:43,630
And let's get into the key 0 1 interface.
95
00:12:43,840 --> 00:12:44,290
First
96
00:12:49,080 --> 00:12:52,070
Okay it's time to take a look to rather from launch first
97
00:13:00,640 --> 00:13:07,000
interface 01 01.
98
00:13:07,170 --> 00:13:18,290
I need to configure an IP address of IP address them for the 1 13 and 1
99
00:13:21,860 --> 00:13:26,030
and No shot.
100
00:13:26,160 --> 00:13:28,200
Let's go to the interface
101
00:13:32,380 --> 00:13:41,690
0 0 2 and my IP address for here will be to have that.
102
00:13:43,580 --> 00:13:44,040
Okay
103
00:13:47,250 --> 00:13:53,840
as you can see that gig 0 2 is 12 that 1
104
00:13:56,390 --> 00:13:59,810
and gig 0 1 is 13.
105
00:13:59,810 --> 00:14:13,990
That what pretty cool pretty straight forward there's no problem we can easily implement the IP addresses
106
00:14:14,140 --> 00:14:20,250
as shown in the figure right son.
107
00:14:21,090 --> 00:14:26,190
Let's take a look to the rather two now.
108
00:14:27,530 --> 00:14:38,700
In rather too I'm going to configure to f that 2 for Dick 0 2 and 20 for that 2 4 6 0 1.
109
00:14:38,780 --> 00:14:39,620
Let's go
110
00:14:49,360 --> 00:14:53,290
either ways geek 0 2.
111
00:14:58,550 --> 00:14:59,560
Together 2
112
00:15:02,440 --> 00:15:07,800
and shut then I'll go to the 0 1
113
00:15:10,950 --> 00:15:17,960
gig 0 1 IP address will be this time 24.
114
00:15:17,960 --> 00:15:19,520
That 2
115
00:15:22,550 --> 00:15:27,170
and no shot right.
116
00:15:32,420 --> 00:15:36,560
I'm seeing a problem but I'm not gonna tell you that now.
117
00:15:38,930 --> 00:15:49,040
Let's go to the rather three now I mean rather tree and let's go to the interface geek.
118
00:15:49,050 --> 00:15:55,600
0 1 which is gonna be IP address
119
00:16:00,250 --> 00:16:12,250
and shut and let's go to the interface geek 0 2 which will have an IP address of
120
00:16:15,040 --> 00:16:24,330
thought for that 3 and with a subnet mask of 2 4 5 2 4 5 2 4 5 0
121
00:16:27,020 --> 00:16:33,430
and the last step is we are gonna take a look to the rather far
122
00:16:36,360 --> 00:16:41,340
interface geek 0 1.
123
00:16:41,430 --> 00:16:46,300
We'll have an IP address of 24 for
124
00:16:49,650 --> 00:17:01,980
no shot and interface Duke 0 2 will have an IP address of
125
00:17:06,150 --> 00:17:07,950
30 for that for
126
00:17:10,570 --> 00:17:12,400
and notion.
127
00:17:13,430 --> 00:17:17,290
As I told you that I'm seeing a problem in the figure
128
00:17:20,100 --> 00:17:24,300
please pay attention that everywhere is in green.
129
00:17:24,300 --> 00:17:36,680
That means there's not a physical problem between that devices but I have red dots between rather one
130
00:17:36,680 --> 00:17:43,020
and rather two which means there is a physical problem between these two riders.
131
00:17:43,190 --> 00:17:53,920
So to fix it I need to check the configuration of the 0 2 for both rudders that score
132
00:17:58,260 --> 00:17:58,900
0 2
133
00:18:01,920 --> 00:18:05,700
please remember that to either to verify the interface
134
00:18:08,640 --> 00:18:20,940
configuration I'm using show IP interface grief comment and as you can see that for Dick 0 2 I have
135
00:18:20,940 --> 00:18:23,390
a problem.
136
00:18:23,520 --> 00:18:37,380
The problem is status of this port is still administratively down which shows me that I forgot to type
137
00:18:37,920 --> 00:18:39,550
no shut
138
00:18:44,790 --> 00:18:50,700
gig 0 2 and No shut.
139
00:18:50,930 --> 00:18:57,530
And as you can see the blind protocol on the interface digs zero to change data up which means physical
140
00:18:57,530 --> 00:19:03,410
problem is not with us anymore and everywhere is green
141
00:19:06,170 --> 00:19:12,280
and that means we have completed the second step.
142
00:19:13,380 --> 00:19:14,250
To also
143
00:19:17,660 --> 00:19:23,510
alright pretty cool I know that that's not an easy lip.
144
00:19:24,680 --> 00:19:34,340
For you guys but you learn lots of things when you accomplish and where you learn the details of this
145
00:19:34,340 --> 00:19:34,720
lab.
146
00:19:36,930 --> 00:19:41,030
All right let's start with the third step.
147
00:19:41,110 --> 00:19:54,760
Third step tells us for use static routing or all routers to provide full connect to 80 between all
148
00:19:54,760 --> 00:20:09,100
pieces in the net work not our that's the real most important part of the left and First we need to
149
00:20:09,100 --> 00:20:11,230
understand what's going on.
150
00:20:13,300 --> 00:20:23,560
Okay to comb for your aesthetic grout for example let's say that I'm going to configure a static rock
151
00:20:23,600 --> 00:20:25,670
for rather three
152
00:20:28,750 --> 00:20:39,360
four rather three but which networks should I teach two rather three and where I'm gonna send the packet.
153
00:20:39,360 --> 00:20:40,610
I have two questions
154
00:20:43,700 --> 00:20:44,830
and four other one.
155
00:20:45,410 --> 00:20:48,240
Which networks should I teach for the other one.
156
00:20:49,840 --> 00:20:55,820
And where I should send the packet first.
157
00:20:55,890 --> 00:20:59,890
I need to define this.
158
00:21:00,170 --> 00:21:05,430
Then I'm gonna write the static grounding comments today.
159
00:21:05,540 --> 00:21:12,060
Rather's as you'll remember from our first sections.
160
00:21:12,290 --> 00:21:23,720
Well I told you is Rather's already known the networks which they're directly connected for example
161
00:21:23,720 --> 00:21:28,180
rather three is directly connected to here.
162
00:21:29,710 --> 00:21:37,490
Here and here so I don't need to say.
163
00:21:37,560 --> 00:21:38,930
Rather treated.
164
00:21:39,000 --> 00:21:51,920
Hey man if you have a picket which destination is thirty three that zero network sent Packer to somewhere
165
00:21:53,740 --> 00:21:57,330
because rather already knows here.
166
00:21:57,700 --> 00:22:11,120
Rather says that on my dick 0 0 interface I have third to 33 the zero network already.
167
00:22:11,200 --> 00:22:26,750
Let's take a look to the rather for rather four is directly connected to here here and here so I don't
168
00:22:26,750 --> 00:22:29,090
need to say two rather four.
169
00:22:29,090 --> 00:22:38,510
For example if you have a packet which destination is twenty four that zero network you need to send
170
00:22:38,510 --> 00:22:51,100
packet the some interface because rather all four already knows that I have four twenty four network
171
00:22:51,700 --> 00:22:58,300
connected to my dick 0 1 interface I don't need to learn it.
172
00:22:59,110 --> 00:23:02,390
OK so
173
00:23:06,090 --> 00:23:07,030
on it to
174
00:23:10,570 --> 00:23:24,070
use static grounding for rather three to teach the networks that rather three is not directly connected
175
00:23:27,250 --> 00:23:37,690
so far rather three I need two static IP riding statements for this that works eleven
176
00:23:41,530 --> 00:23:45,320
twelve twenty two
177
00:23:48,370 --> 00:23:52,550
for 24.
178
00:23:54,560 --> 00:24:07,170
Forty four right cars rather three is not directly connected to this networks and rather three doesn't
179
00:24:07,170 --> 00:24:22,210
know how to get this network's so I'm going to teach these networks two rather three using the static
180
00:24:22,300 --> 00:24:26,170
IP configuration right
181
00:24:31,760 --> 00:24:44,860
let's say that four we have let's take a look while we have for the rather one also for other one I
182
00:24:44,860 --> 00:24:56,980
need to use the static IP configuration for this networks this is gonna be a rather one and I'm not
183
00:24:56,980 --> 00:24:57,650
I use
184
00:25:00,360 --> 00:25:10,150
to third and fourth quarter for 24 and 22 right.
185
00:25:13,150 --> 00:25:23,680
I hope there is no problem about this depth and you can easily get this because that's really really
186
00:25:23,680 --> 00:25:37,470
important portion of the static networking and it's time to take a look for the rather two very rather
187
00:25:37,560 --> 00:25:41,850
too does is not directly connected.
188
00:25:42,230 --> 00:25:42,660
Are
189
00:25:45,270 --> 00:25:45,850
eleven
190
00:25:48,580 --> 00:25:57,440
13 33 34 round 44 OK.
191
00:25:59,100 --> 00:26:01,530
I completed this one to
192
00:26:04,870 --> 00:26:08,420
and is time to take a look for the.
193
00:26:08,500 --> 00:26:15,540
Our last trailer which is rather for four other four.
194
00:26:16,260 --> 00:26:22,630
I need to use static ip reading statements for web
195
00:26:25,510 --> 00:26:30,290
there is this this
196
00:26:33,540 --> 00:26:35,730
is and
197
00:26:39,420 --> 00:26:43,330
this okay.
198
00:26:43,400 --> 00:26:44,570
There is no problem
199
00:26:47,000 --> 00:26:56,230
and no I define that for which networks I'm going to use to the drawing.
200
00:26:56,500 --> 00:27:07,890
Statements for example 4 rather one I'm going to get and the other one and say this guy Hey man hey
201
00:27:07,890 --> 00:27:08,880
rather wrong.
202
00:27:10,530 --> 00:27:26,460
If you have a packet which has a destination network idea of ten forty one thirty three that zero send
203
00:27:26,490 --> 00:27:30,560
the packet to here
204
00:27:33,700 --> 00:27:34,200
okay
205
00:27:39,050 --> 00:27:43,670
I'm going to say the error thing for this network to
206
00:27:46,890 --> 00:27:54,150
hey rather run if you have something that you don't know send the packet to this guy
207
00:27:57,670 --> 00:28:10,860
and I'm going to get into the other two and I will say the to the Hey man if you have packets which
208
00:28:10,860 --> 00:28:17,910
has a destination of this that works send the packet to
209
00:28:21,470 --> 00:28:21,920
here
210
00:28:26,450 --> 00:28:36,140
here I mean here I'm going to say rather for send the packets here and I'm going to say rather treat
211
00:28:36,170 --> 00:28:40,440
to send the packets to.
212
00:28:40,730 --> 00:28:48,030
So what I'm doing is I'm covering all the network as you see with the circle.
213
00:28:48,470 --> 00:28:57,390
For example if rather one has for example let's say the P.C. one wants to communicate with P.C. two
214
00:28:58,170 --> 00:29:06,710
packet loop counter other one rather one will check the destination address and we'll see that that's
215
00:29:07,010 --> 00:29:17,290
twenty two that zero and we'll send the packet to here rather two will get this packet and rather two
216
00:29:17,290 --> 00:29:26,850
is directly connected here as you know and we'll forward the package to a piece it would directly but
217
00:29:26,880 --> 00:29:28,950
if piece one wants to communicate to it.
218
00:29:28,950 --> 00:29:40,260
P.S. For rather two will also get the packet and send it to rather for and because of four other four
219
00:29:40,260 --> 00:29:45,060
is directly connected to you that's gonna send the packet to the PCI for.
220
00:29:45,290 --> 00:29:55,680
That's the logic behind this please pay attention that I will do this month to I could go to the rather
221
00:29:55,680 --> 00:30:08,470
one and say that hey man if somebody wants to go to third three that zero sir packet Derek blue here
222
00:30:12,010 --> 00:30:26,430
that would also work but for simplicity I'm just defining one way as a circle and I'm sending the packets
223
00:30:26,430 --> 00:30:36,120
on that way you can also give it a try to sending for different points too there's no problem about
224
00:30:36,120 --> 00:30:37,860
it.
225
00:30:38,780 --> 00:30:39,390
All right.
226
00:30:39,390 --> 00:30:50,940
Now it's time to go to the packet tracer again and I will make our configurations there that talk about
227
00:30:53,370 --> 00:30:57,660
oh my god my seal is broken and it's lucky right now
228
00:31:01,090 --> 00:31:15,880
OK and let's go enable comic my static growth config is like this as you can remember from our previous
229
00:31:15,880 --> 00:31:26,680
slides it's IP rout IP out question mark I say is also that right.
230
00:31:26,680 --> 00:31:34,230
The destination prefix okay for rather one my destination prefixes are
231
00:31:38,960 --> 00:31:43,640
this is the destination that took subnet mask and
232
00:31:47,410 --> 00:31:52,830
I'm going to write the forwarding Rather's address where I'm going to send the packet
233
00:32:02,040 --> 00:32:12,360
OK Uno is now OK sorry sir so sorry anchor I'm configuring the rather one so I don't need to teach this
234
00:32:12,360 --> 00:32:20,510
guy to eleven because it's directly connected so I need to start with this maybe
235
00:32:29,990 --> 00:32:30,740
this through
236
00:32:34,960 --> 00:32:35,740
44
237
00:32:39,200 --> 00:32:40,940
24 and
238
00:32:44,450 --> 00:32:50,820
22 here is my whole configuration force that craft
239
00:32:55,920 --> 00:33:00,600
let's take a look to this portion I peer out
240
00:33:04,300 --> 00:33:13,190
ten forty one twenty to zero and subnet mask off the destination network send the packet to
241
00:33:16,120 --> 00:33:20,570
twelve that 2 which is rather 2 Alright
242
00:33:24,720 --> 00:33:35,070
that's got 2 did rather 2 now in rather 2 I'm going to define eleven thirteen thirty three thirty four
243
00:33:35,070 --> 00:33:44,140
and forty four as you remember because the other networks are directly connected and I don't need to
244
00:33:44,650 --> 00:33:48,790
teach them two rather true I appear out
245
00:33:58,790 --> 00:34:01,280
where I'm going to send the packets for mother two years
246
00:34:08,070 --> 00:34:08,480
this one.
247
00:34:09,380 --> 00:34:12,020
With star power as of the rather four
248
00:34:15,260 --> 00:34:17,840
and I'm gonna configure this for a lower
249
00:34:20,540 --> 00:34:21,350
13
250
00:34:24,120 --> 00:34:25,110
33
251
00:34:28,410 --> 00:34:30,750
34 and 40 for
252
00:34:34,740 --> 00:34:38,220
OK cool.
253
00:34:38,380 --> 00:34:41,870
Hey guys please warn me if I'm doing something wrong.
254
00:34:42,070 --> 00:34:44,220
OK.
255
00:34:44,290 --> 00:34:49,170
Enable com fake IP rout.
256
00:34:49,180 --> 00:34:51,340
Come on man what's going on with you.
257
00:34:52,520 --> 00:34:53,390
I out
258
00:35:03,410 --> 00:35:06,330
it's going to be rather long this time
259
00:35:11,270 --> 00:35:17,050
well 20 to 24.
260
00:35:19,330 --> 00:35:29,830
And Fordham for awesome at least it looks awesome.
261
00:35:29,860 --> 00:35:30,610
I hope so.
262
00:35:30,610 --> 00:35:31,560
It's ours.
263
00:35:31,930 --> 00:35:36,690
We are gonna check if there's something wrong or not.
264
00:35:37,150 --> 00:35:40,560
In the last step enable
265
00:35:43,250 --> 00:35:44,470
I peer out
266
00:35:49,840 --> 00:35:58,730
send the packets to rather to interface right.
267
00:35:59,080 --> 00:36:06,470
I'm going to also teach the is this guy
268
00:36:11,630 --> 00:36:13,490
this network also
269
00:36:16,310 --> 00:36:17,000
this network
270
00:36:20,030 --> 00:36:22,420
Oh right.
271
00:36:22,640 --> 00:36:29,810
It seems like everything is okay right now but I should wear.
272
00:36:32,020 --> 00:36:35,980
If all my configurations are okay
273
00:36:39,250 --> 00:36:41,770
I should pass these tests.
274
00:36:41,770 --> 00:36:52,860
For example I should ping Pacer 2 from PS1 or I should ping pacing for from P.S. 3 but I'm going to
275
00:36:52,860 --> 00:36:57,600
use to ping from P.S. 1 2.
276
00:36:58,080 --> 00:37:02,610
P.S. 4 for example.
277
00:37:02,800 --> 00:37:07,020
P.S. Once the IP address is 11 that 5
278
00:37:10,850 --> 00:37:15,560
NPC four's IP is 44 that 5.
279
00:37:16,550 --> 00:37:17,590
Let's go.
280
00:37:17,780 --> 00:37:20,300
Please please work.
281
00:37:22,530 --> 00:37:23,370
Alright guys.
282
00:37:23,420 --> 00:37:24,380
No problem.
283
00:37:24,470 --> 00:37:32,000
If we have some problem about the configuration we are gonna quickly trouble shoot it and I'm going
284
00:37:32,000 --> 00:37:39,020
to show you how we troubles should step by step and we are gonna give you a quick solution for the problem
285
00:37:39,020 --> 00:37:40,000
too.
286
00:37:40,160 --> 00:37:49,720
Also but it's better that I prefer that it works and it to show you this one too.
287
00:37:50,230 --> 00:37:58,130
I'm getting into the P.C. and I need to open a command prompt to use the pink command on a P.C..
288
00:37:58,450 --> 00:38:00,220
Here is my comment.
289
00:38:00,250 --> 00:38:00,820
Paying
290
00:38:03,460 --> 00:38:10,300
then 41 for the 4.5 and under
291
00:38:14,980 --> 00:38:15,870
please.
292
00:38:15,880 --> 00:38:19,330
Please work please work please work please work.
293
00:38:19,450 --> 00:38:21,280
Please work please work.
294
00:38:21,910 --> 00:38:23,980
It's not working.
295
00:38:25,860 --> 00:38:27,110
Not another.
296
00:38:27,110 --> 00:38:28,620
Here is the band here.
297
00:38:28,650 --> 00:38:29,630
It's not working
298
00:38:32,170 --> 00:38:32,950
OK.
299
00:38:35,520 --> 00:38:36,990
That's really cool for me
300
00:38:40,240 --> 00:38:42,320
you will learn something more.
301
00:38:42,320 --> 00:38:43,190
That means
302
00:38:47,300 --> 00:38:55,830
it's working in a more we don't need to troubleshoot because it's hard working.
303
00:38:55,840 --> 00:38:59,530
I don't know why pick a choice there.
304
00:38:59,770 --> 00:39:06,800
Sometimes may do some weird things like this but our ping is working right now
305
00:39:09,610 --> 00:39:16,090
so we don't need to travel ship but I'm gonna try to paint from this guy to here too and check what's
306
00:39:16,090 --> 00:39:16,720
going on.
307
00:39:19,180 --> 00:39:30,210
Let's go comment prom and let me check the IP address thirty three the five
308
00:39:37,630 --> 00:39:38,770
and let's check it
309
00:39:43,580 --> 00:39:54,840
it's working is working as we don't need to worry about our configuration right now because I can pick
310
00:39:55,610 --> 00:40:06,210
the pieces from each other that means I'm verifying my configuration pretty cool pretty straightforward
311
00:40:06,250 --> 00:40:13,990
there's no problem seriously on my network now everyone can reach everywhere it seems like I don't know
312
00:40:13,990 --> 00:40:18,510
if there's a little problems with other devices but I don't think so.
313
00:40:18,730 --> 00:40:24,970
But what if if we would have a problem and how we could trouble should it.
314
00:40:25,000 --> 00:40:37,800
Let's take a look over at this if I couldn't paint from P.S. 1 2 P.S. 3 what I would do the first thing
315
00:40:37,800 --> 00:40:39,870
and to check is the default.
316
00:40:39,870 --> 00:40:42,860
Get me off the P.C. one.
317
00:40:43,860 --> 00:40:45,200
Let's take a look to the default.
318
00:40:45,210 --> 00:40:57,830
Get the Default Gateway is 10 41 11am 1 which is the IP address of the disk 0 0 interface of my routers.
319
00:40:58,650 --> 00:41:11,000
And first I can take a look that if I have a connection to my default gateway or not by using pinging
320
00:41:11,010 --> 00:41:22,680
the default gateway as you can see that there's no problem I can ping my default gateway if I couldn't
321
00:41:22,680 --> 00:41:34,570
pin my default gateway if I wouldn't be able to pick my default pay I will check the geek.
322
00:41:34,570 --> 00:41:48,150
0 0 interfaces IP configuration first OK the second step that I can loop that if package is reaching
323
00:41:48,150 --> 00:42:01,790
here my gateway ping is successful and if I wouldn't still pink the P.C. for in here what I should check
324
00:42:01,790 --> 00:42:12,880
is the IP address configuration of the interfaces and the static IP configurations of the by using
325
00:42:15,420 --> 00:42:17,670
show IP.
326
00:42:18,660 --> 00:42:34,050
Static common or I could also check this by using show run comment to as you can see that from the output
327
00:42:34,920 --> 00:42:43,710
I have my static graphs for 22 okay 24.
328
00:42:43,740 --> 00:42:54,350
Okay thirty two and thirty four and for the 440 rather one which means I have a static graph for my
329
00:42:54,860 --> 00:42:59,800
destination that work that piece of for belongs to.
330
00:42:59,850 --> 00:43:00,660
That's great.
331
00:43:00,690 --> 00:43:01,610
That's cool.
332
00:43:01,830 --> 00:43:04,330
And my configuration is working.
333
00:43:06,980 --> 00:43:11,100
And it's time to check the third step.
334
00:43:13,980 --> 00:43:14,960
And unless the
335
00:43:18,090 --> 00:43:25,220
ballclub saves me that she run the show IP protocols and sure to Rudd commands and check the output
336
00:43:28,530 --> 00:43:33,640
let's use the show IP protocols commented on rather run and
337
00:43:38,250 --> 00:43:41,050
I can not see anything what's going on.
338
00:43:41,930 --> 00:43:42,760
What's going on man.
339
00:43:42,770 --> 00:43:45,260
We made something wrong.
340
00:43:45,310 --> 00:43:49,010
No actually we didn't make something wrong.
341
00:43:49,120 --> 00:43:50,540
Everything is right.
342
00:43:50,560 --> 00:44:01,810
This is the output that I accept to see because I didn't use any dynamic routing protocols because of
343
00:44:01,810 --> 00:44:04,760
I didn't use in dynamic crafting protocols.
344
00:44:04,760 --> 00:44:17,030
Show IP protocols output is actually nothing because I used static writhing and the second come on this
345
00:44:17,360 --> 00:44:18,650
show IP out
346
00:44:21,860 --> 00:44:33,050
and as you can see that I had directly connect that interfaces automatically appearing on my rather
347
00:44:33,920 --> 00:44:40,640
and the local interface of the rather is appearing automatically too also.
348
00:44:41,120 --> 00:44:50,090
And these lines are appearing after the configuration of the static rather that we made on our previous
349
00:44:50,540 --> 00:44:51,320
steps.
