00:00:00,060 --> 00:00:00,510
Hi, Daddy.

2
00:00:00,510 --> 00:00:01,620
This my heart out here again?

3
00:00:01,860 --> 00:00:07,080
In this lecture, I have to show you how you can configure the Agent B version one on the Mac, the

4
00:00:07,080 --> 00:00:07,800
crossroads.

5
00:00:08,250 --> 00:00:10,290
As you can see here, we have a level of seven points.

6
00:00:10,560 --> 00:00:16,020
But before I start doing those points, let me just go and show you some explanation about the IGP version

7
00:00:16,020 --> 00:00:19,980
one, how it works and what is the mechanism behind it.

8
00:00:20,190 --> 00:00:26,100
And then after that I will come back to the points I started with them so I can be version one is the

9
00:00:26,310 --> 00:00:28,080
protocol that we said.

10
00:00:28,080 --> 00:00:34,470
It's used by a host to inform the master castrato that he wants to receive the multicast traffic.

11
00:00:34,830 --> 00:00:40,200
As I said that my critic, they wish to have a capacity to use this free version of version one, 2

12
00:00:40,200 --> 00:00:40,560
to 3.

13
00:00:40,560 --> 00:00:44,220
So Voyager one is the oldest one, but I'm going to cover it in this course.

14
00:00:44,940 --> 00:00:47,430
So I'm going to be version one is very simple.

15
00:00:47,430 --> 00:00:48,480
It has two messages.

16
00:00:48,480 --> 00:00:51,540
We have the membership report and we have the membership query.

17
00:00:51,840 --> 00:00:57,240
So say that you have here, as I said, a router and this author is connected to a computer.

18
00:00:58,800 --> 00:01:01,170
Now, any time that this computer wants to receive the.

19
00:01:01,260 --> 00:01:01,800
I think so.

20
00:01:01,980 --> 00:01:04,320
Let's say that that is the server or the router over here.

21
00:01:04,560 --> 00:01:06,480
It's connected to a streaming server.

22
00:01:07,080 --> 00:01:10,650
So it's making streaming and the multicast is coming to the router.

23
00:01:10,980 --> 00:01:15,590
Now, this computer, if you want to receive the streaming, then he will send something.

24
00:01:15,600 --> 00:01:17,400
We call it the membership report.

25
00:01:17,400 --> 00:01:18,150
So let's read it.

26
00:01:18,510 --> 00:01:23,850
The host use this matches when it wants to join in multicast group by sending it to the group address

27
00:01:23,850 --> 00:01:25,680
that it wants to receive the multicast stream.

28
00:01:26,040 --> 00:01:30,000
So we will see at a moment that once you want to enable the market that you have to make a multicast

29
00:01:30,000 --> 00:01:35,130
group and then this computer will send the membership report to that multicast group.

30
00:01:35,130 --> 00:01:40,110
This group thereafter knows about it, the server here knows about it, and of course, the computer

31
00:01:40,110 --> 00:01:41,880
or the receiver also knows about it.

32
00:01:43,230 --> 00:01:50,010
Now why is the multicast enabled router that means this router receive this meshes it will start forwarding

33
00:01:50,010 --> 00:01:53,400
about the catastrophic all the interface that it has received.

34
00:01:53,400 --> 00:02:01,590
The IGP membership report also this was signed the membership report and this rather would start sending

35
00:02:02,220 --> 00:02:08,970
the multicast traffic to that computer because he knows that this computer want to have the MARTA catastrophic.

36
00:02:09,240 --> 00:02:14,040
So again, membership report is sent always from the host to join a multicast group.

37
00:02:14,040 --> 00:02:18,450
So that means to receive the multicast traffic.

38
00:02:18,840 --> 00:02:22,920
So now we understand about the membership report, let's see what is the membership query?

39
00:02:23,040 --> 00:02:25,740
Membership query is always sent from the router.

40
00:02:25,740 --> 00:02:31,860
So once he has received the membership report from the router, this router over here always sent a

41
00:02:31,860 --> 00:02:37,920
membership query and he sent it to the destination, which is 2 to 4 .0.0.

42
00:02:37,920 --> 00:02:46,500
The client which is all host and just to check if those computers or those host still need to receive

43
00:02:46,500 --> 00:02:48,030
the multicast streaming.

44
00:02:48,600 --> 00:02:53,010
If he doesn't hear from them for some time, then it has an expiry time.

45
00:02:53,220 --> 00:02:58,260
Then when this is expired, then he will stop sending the multicast.

46
00:02:58,260 --> 00:03:03,360
So again, he will send the this query to all host and guest.

47
00:03:03,360 --> 00:03:05,280
For example, this host is receiving the multicast.

48
00:03:05,280 --> 00:03:06,420
This doesn't reply.

49
00:03:07,110 --> 00:03:12,630
Then in this case the rocker knows that this host doesn't want any more dramatic traffic, and then

50
00:03:12,630 --> 00:03:14,460
it waits until the timer is finished.

51
00:03:14,700 --> 00:03:19,680
And then once it's finished, it will stop sending the multicast streaming to that cost.

52
00:03:20,010 --> 00:03:22,110
So now let's read what is written here.

53
00:03:22,920 --> 00:03:28,980
So the membership query is sent by the router to the destination 2 to 4 .0.0.1, which is all the host

54
00:03:29,400 --> 00:03:30,780
the Multicast Group address.

55
00:03:31,020 --> 00:03:36,180
So that means all the host and the multicast group that is sent periodically by by the router to check

56
00:03:36,180 --> 00:03:38,700
whether the hosts are still interested by the multicast.

57
00:03:38,700 --> 00:03:45,120
So that is it's always being sent by the relative to see if the hosts are still interested in the matter.

58
00:03:45,120 --> 00:03:50,010
Catastrophic when there are to receive membership report back from a particular show.

59
00:03:50,010 --> 00:03:52,590
He sent the membership query.

60
00:03:52,920 --> 00:03:59,850
Then once he receive back a membership report from those hosts, then he knows that this still want

61
00:03:59,850 --> 00:04:05,940
the multicast traffic that what it does done the expiry time of this trotter would be refreshed.

62
00:04:06,300 --> 00:04:09,380
So you know that the expiry time would be going down, down, down, down.

63
00:04:09,540 --> 00:04:17,010
Once you receive back the membership report from the computer, then it will refresh it so it doesn't

64
00:04:17,100 --> 00:04:23,250
let it go to zero because once it's two zero, then he thinks that this all she doesn't want anymore

65
00:04:23,250 --> 00:04:30,180
the traffic for the month of August and then he will stop sending the multicast traffic now in case

66
00:04:30,180 --> 00:04:35,700
she doesn't hear from the host and thereafter with thing that he is no longer interested in the multicast

67
00:04:35,940 --> 00:04:40,680
traffic and will remove it from the Andrea once the timer is zero.

68
00:04:41,250 --> 00:04:43,800
So that's what the membership query is.

69
00:04:43,800 --> 00:04:47,700
Again, it was always sent to all the host on the multicast group.

70
00:04:48,030 --> 00:04:53,140
I think I you hear back from the host then he refreshes timer.

71
00:04:53,140 --> 00:04:54,900
He think that he still want the multicast.

72
00:04:55,560 --> 00:04:58,200
She doesn't hear back and the timer is finished.

73
00:04:58,620 --> 00:04:59,520
Now what it does.

74
00:04:59,860 --> 00:05:03,220
Just take it out and he doesn't send it anymore.

75
00:05:03,430 --> 00:05:05,390
The multicast traffic to that house.

76
00:05:06,100 --> 00:05:10,270
So now we understand, though, what happens on the the HAARP in the background.

77
00:05:10,480 --> 00:05:12,520
Let's see what our love scenario is.

78
00:05:12,520 --> 00:05:17,650
And I will start going to parts of the lab to make the HAARP virtual one configuration.

79
00:05:17,860 --> 00:05:18,820
So that is my lab.

80
00:05:18,820 --> 00:05:20,710
I only use here one router.

81
00:05:21,040 --> 00:05:24,880
So there is no need for them for now because it's only one router.

82
00:05:25,240 --> 00:05:29,820
So what I have done, I just put the IP address that has here ethernet one here internet to it, do

83
00:05:29,830 --> 00:05:37,210
not want it is connected to the streaming server and internet two is connected to the client to the

84
00:05:37,210 --> 00:05:37,930
streaming line.

85
00:05:38,380 --> 00:05:42,910
And I have put the IP addresses on the routers, interfaces on the PCs.

86
00:05:42,910 --> 00:05:46,720
Everything is now configured as for the IP address, and that's it.

87
00:05:47,410 --> 00:05:54,190
Now to make this computer here maybe see streaming or the streaming server, then I'm going to use device

88
00:05:54,190 --> 00:05:56,170
you software, which is a free wash software.

89
00:05:56,170 --> 00:05:57,700
You can get it from the Internet.

90
00:05:57,700 --> 00:05:59,080
Now you download it for free.

91
00:05:59,590 --> 00:06:06,280
And I'm going to stream here some videos that I will use here also obviously to make it ABC client and

92
00:06:06,280 --> 00:06:13,540
I want to receive the multicast after I configure ICMP version WAN on this rather.

93
00:06:14,410 --> 00:06:19,420
And now after we do that, we'll see if this computer will be receiving the streaming that is being

94
00:06:19,420 --> 00:06:21,640
sent from this picture.

95
00:06:22,060 --> 00:06:30,970
And after that, I will close the VSC over here and we will see if this router will stop sending the

96
00:06:30,970 --> 00:06:37,360
traffic or it waits for the expiry time to finish done stop the traffic for the month of August.

97
00:06:37,900 --> 00:06:39,790
So this is all what we are going to do in this stop.

98
00:06:39,970 --> 00:06:42,550
Let's go now back to the ports and start doing them both.

99
00:06:42,550 --> 00:06:46,690
Number one, all IP addresses are set as per the graph on the species of the router.

100
00:06:46,690 --> 00:06:52,000
So let me just put the picture so you can follow me when I'm doing the ports and this part is done.

101
00:06:52,000 --> 00:06:53,320
If you want, I can just show you.

102
00:06:53,650 --> 00:06:55,570
So that is the router.

103
00:06:56,260 --> 00:06:57,580
What I have done over here.

104
00:06:57,580 --> 00:07:04,030
Just put the IP addresses on Ethernet to an Ethernet WAN as on the graph and also I put on the computer.

105
00:07:04,030 --> 00:07:10,660
So if you want, I can just go to my computer here, which is this computer that I'm recording the video.

106
00:07:10,660 --> 00:07:13,750
Is this the Velshi client is going to be okay.

107
00:07:14,230 --> 00:07:22,030
So you can see it has IP config, the IP that it has one or two or say the two, the two as per the

108
00:07:22,030 --> 00:07:22,480
graph.

109
00:07:22,720 --> 00:07:31,750
So that means if I think to the router on a19 2168.2.1, it has a reply so you can see it's working

110
00:07:31,750 --> 00:07:32,770
without any problem.

111
00:07:33,280 --> 00:07:35,440
So now the IP address are set.

112
00:07:35,440 --> 00:07:37,460
So let's see what we have to do in the upcoming well.

113
00:07:37,600 --> 00:07:43,660
What number to configure HAARP version one on the interfaces ethernet one to enter are two of their

114
00:07:43,660 --> 00:07:43,960
output.

115
00:07:44,680 --> 00:07:49,540
So how to configure the IGP very well.

116
00:07:49,540 --> 00:07:50,860
You can see it's straightforward.

117
00:07:50,860 --> 00:07:51,610
It's really easy.

118
00:07:51,610 --> 00:07:59,740
Look, you go to routing and then you go to them, you see this one and now let me just make it bigger.

119
00:07:59,740 --> 00:08:08,500
You have the interfaces you go to plus and you say, I want new PIM interface and I want it to be on

120
00:08:08,500 --> 00:08:14,140
Ethernet one and you check them and IGP, someone can say, but we are talking about IGP, why I need

121
00:08:14,140 --> 00:08:14,950
to check them.

122
00:08:15,400 --> 00:08:18,220
Well, on my take you have to enable them.

123
00:08:18,310 --> 00:08:24,820
Otherwise the multicast is not going to be functional even though that bin will not be used as protocol.

124
00:08:25,090 --> 00:08:27,190
But if you uncheck it then it's not going to work.

125
00:08:27,190 --> 00:08:34,990
So you have to put pen and IGP so it's not one and done with Chuck Berman on jeopardy by default over

126
00:08:34,990 --> 00:08:37,750
here it choose the IGP that you want.

127
00:08:37,900 --> 00:08:40,930
In my case I'm going to use I GMP version one.

128
00:08:41,260 --> 00:08:43,450
Version two is the default one on the my critic.

129
00:08:43,840 --> 00:08:47,770
But I'm going to use the IGP version one just to show you what's going to happen.

130
00:08:47,770 --> 00:08:51,060
So this is done on the interface Ethernet one.

131
00:08:51,070 --> 00:08:58,480
I do also the same on interface Ethernet two and and I enable IGP version one them, IGP and I both.

132
00:08:58,480 --> 00:09:02,080
And that's just so that's all you need to do on the MAC.

133
00:09:02,080 --> 00:09:07,450
The greater SD configuration is not a big deal, but number two is dump both arbitrary check of the

134
00:09:07,450 --> 00:09:11,500
streaming server has a for the multicast group +39 .122 the three.

135
00:09:11,800 --> 00:09:18,940
So I'm going to use the multicast group 239.12 to the Qri as being the addition I should address as

136
00:09:18,940 --> 00:09:22,010
I said for you again, remember the cost.

137
00:09:22,010 --> 00:09:23,230
You should be on the destination.

138
00:09:23,230 --> 00:09:29,680
You can choose the across the IP address that you want I'm going to use to and I responded to the stream.

139
00:09:30,940 --> 00:09:33,730
So that means the streaming will be going to that group.

140
00:09:33,850 --> 00:09:43,480
Now if we go to the server because remember if we go back to here to the picture, the, the computer

141
00:09:43,480 --> 00:09:48,520
over here has a gateway which is this one, right?

142
00:09:48,520 --> 00:09:49,510
That's what he has.

143
00:09:49,750 --> 00:09:53,710
But that it is only for unicast for the, for the multicast.

144
00:09:53,710 --> 00:09:57,880
It does know that how to send it to 39.12 to the street.

145
00:09:57,880 --> 00:09:59,230
So this is the destination.

146
00:09:59,610 --> 00:10:05,520
So if we go to the computer and we look now inside the gateways or the routing table of the third of

147
00:10:05,520 --> 00:10:12,240
the APC, you'll see that all the entries he asked, he doesn't know anything about 239.122.3.

148
00:10:12,780 --> 00:10:18,530
So what I need to do is to just go to that server and I have to enable a route.

149
00:10:18,540 --> 00:10:19,650
I make it statically.

150
00:10:20,100 --> 00:10:24,420
That means I have to say to go to 239.122.3.

151
00:10:24,780 --> 00:10:29,580
Then send everything to your next hop, which is this IP others one and 2.1.1.

152
00:10:29,910 --> 00:10:32,070
You understand because you will see.

153
00:10:32,070 --> 00:10:33,560
Now, let me show you directly why?

154
00:10:33,560 --> 00:10:34,710
Why to just talk.

155
00:10:35,160 --> 00:10:37,170
I will go to the.

156
00:10:38,340 --> 00:10:39,370
There is the server.

157
00:10:39,420 --> 00:10:39,900
All right.

158
00:10:40,170 --> 00:10:41,000
I will go to here.

159
00:10:41,010 --> 00:10:44,120
Now, I cannot write from any of us.

160
00:10:44,130 --> 00:10:45,270
I will go from here directly.

161
00:10:45,270 --> 00:10:48,870
I'm right on the server right away, right up to print.

162
00:10:49,950 --> 00:10:56,940
So if you say right to print over here, look, it will show for you the routes that this computer knows,

163
00:10:57,780 --> 00:10:59,120
but it doesn't have anything.

164
00:10:59,130 --> 00:11:00,390
Look at this destination.

165
00:11:00,390 --> 00:11:01,380
It doesn't have anything.

166
00:11:01,380 --> 00:11:03,950
Call 239.122.3.

167
00:11:03,960 --> 00:11:06,270
You see, those are the destinations.

168
00:11:07,230 --> 00:11:12,120
So what I need to do, I have to create a route manually on this computer.

169
00:11:13,310 --> 00:11:13,860
All right.

170
00:11:13,890 --> 00:11:22,320
Now, if you are using some some different streaming servers, then it may happen that you have to put

171
00:11:22,320 --> 00:11:23,960
it on the software directly there.

172
00:11:24,630 --> 00:11:30,300
But now, because I'm using just simple B, I see that I have to do it on the Windows machine, on the

173
00:11:30,300 --> 00:11:31,690
Mac, on the on the Linux.

174
00:11:31,710 --> 00:11:36,870
Also, you can make routes yourself for the same as I'm doing right now.

175
00:11:37,200 --> 00:11:37,930
So how to do that.

176
00:11:38,190 --> 00:11:50,250
I just have to say route had to go to 239.1.2.3 which has a mask of 255255255255.

177
00:11:50,490 --> 00:11:55,290
So that means to go to that particular IP, which is to say 9.1.2.3.

178
00:11:55,290 --> 00:12:02,430
If you say 255255245245, that means you are matching all the optics of the IP that sent everything

179
00:12:02,430 --> 00:12:07,110
to your next hop, which is 112168.1.1.

180
00:12:07,840 --> 00:12:08,280
All right.

181
00:12:08,580 --> 00:12:12,570
Which is if you look to the picture, the server, that is his gateway.

182
00:12:12,870 --> 00:12:19,230
And then I'll say here, until now, if I make a go print, we can see that this entry has been showed

183
00:12:19,230 --> 00:12:20,190
up over here.

184
00:12:20,790 --> 00:12:29,040
So now I can if I if this server is sending the multicast to 239.122.3, he knows that he has to send

185
00:12:29,040 --> 00:12:31,950
it to it and that one on internet one will have IP.

186
00:12:32,160 --> 00:12:33,980
So then the multicast would work.

187
00:12:33,990 --> 00:12:39,120
So you got the idea but obviously is not one number four add around on the streaming server.

188
00:12:39,120 --> 00:12:40,170
We have already done that.

189
00:12:40,560 --> 00:12:43,800
So this path is also going we have added the row.

190
00:12:44,610 --> 00:12:50,460
Now what we need to do is to start the streaming on the streaming server.

191
00:12:50,460 --> 00:12:52,830
So we have just to start doing the streaming.

192
00:12:53,160 --> 00:12:57,450
Now, all you need to do is to go to Velshi

193
00:13:00,600 --> 00:13:06,150
and then from here you have to go to a stream that is D server.

194
00:13:06,150 --> 00:13:06,510
All right.

195
00:13:06,510 --> 00:13:07,620
Now I'm on the server.

196
00:13:08,220 --> 00:13:14,610
I would add I'll just add one of my videos that I have published on YouTube top to block PUBG.

197
00:13:15,090 --> 00:13:17,310
So I will add this video.

198
00:13:18,780 --> 00:13:20,190
And then I'll click on stream.

199
00:13:21,210 --> 00:13:23,800
Now it will say to me, set up media sources.

200
00:13:23,800 --> 00:13:25,410
So here you have to say next.

201
00:13:26,190 --> 00:13:32,100
Now you can use, if you want of DSP or RTP, I'm going to use UDP.

202
00:13:32,220 --> 00:13:32,680
Alright.

203
00:13:32,730 --> 00:13:38,520
You can use those other protocols I'm going to use here, the UDP and then I have to say add.

204
00:13:39,900 --> 00:13:45,450
So where shall I send this multicast or this video to the multicast group which had those.

205
00:13:45,450 --> 00:13:47,980
39.1.2.3?

206
00:13:48,000 --> 00:13:48,540
Correct.

207
00:13:48,990 --> 00:13:50,670
That's what we have made around for it.

208
00:13:50,960 --> 00:13:53,040
I remember the port as one, two, three, four.

209
00:13:53,040 --> 00:13:54,690
You can put the port that you want.

210
00:13:54,930 --> 00:13:55,950
I'm going to leave it.

211
00:13:55,950 --> 00:13:56,790
One, two, three, four.

212
00:13:57,450 --> 00:13:59,160
And then I'm saying, Max.

213
00:13:59,850 --> 00:14:02,600
Now, here, you can choose the profile by default.

214
00:14:02,610 --> 00:14:10,190
I'm going to choose the video as a point to six, four plus IP three out before I activate the transcoding.

215
00:14:10,200 --> 00:14:14,880
So here you have to say max and that stream all elementary streams.

216
00:14:15,180 --> 00:14:16,460
And then I'll say here next.

217
00:14:16,830 --> 00:14:20,400
So believe it or not, now this video has started streaming.

218
00:14:20,520 --> 00:14:27,990
So if we go to the microphone now, we go to the interfaces, we shall see that already Ethernet one

219
00:14:27,990 --> 00:14:31,410
to look at is getting 2.3 megabits per second.

220
00:14:31,420 --> 00:14:35,190
That's the streaming that is coming to the router.

221
00:14:35,490 --> 00:14:42,030
But on the Internet, do nothing yet because we didn't enable the device required to receive this streaming

222
00:14:42,030 --> 00:14:42,420
video.

223
00:14:43,420 --> 00:14:43,900
Excellent.

224
00:14:44,260 --> 00:14:50,290
Now, the other thing that I want to show you here is if we go to the open and we go to John's, we

225
00:14:50,290 --> 00:14:51,100
can see that.

226
00:14:52,240 --> 00:14:56,830
You see, this is the group to see now that one the to the SRI is coming from the source, which is

227
00:14:56,830 --> 00:14:57,910
my server.

228
00:14:58,330 --> 00:15:00,050
So it has John already.

229
00:15:00,670 --> 00:15:01,140
Excellent.

230
00:15:01,150 --> 00:15:03,160
So this is already now done.

231
00:15:03,490 --> 00:15:07,990
Now let's see what we have to do in the upcoming phone to make it work on the client side.

232
00:15:08,290 --> 00:15:09,600
What number five is done?

233
00:15:09,790 --> 00:15:15,280
Number six, go to the streaming receiver and add the URL of the streaming server, which is the UDP

234
00:15:15,280 --> 00:15:23,490
that I have created with the IP of 239.12.23 and with the port 1234 and did the multicast works.

235
00:15:23,490 --> 00:15:24,130
So let's do that.

236
00:15:24,790 --> 00:15:30,220
Now I am on my computer and again this computer is declining, so I will open v s you.

237
00:15:30,940 --> 00:15:39,940
Now this is the client side and over here I have to go to media and open network stream and I will use

238
00:15:39,940 --> 00:15:45,280
this notation UDP call on slash slash.

239
00:15:45,280 --> 00:15:51,820
And then you have to say at this thing I wanted to the three and then you put one, two, three, four,

240
00:15:52,090 --> 00:15:54,670
which is the port and you have to say play.

241
00:15:56,790 --> 00:15:58,170
So let's see if it's going to work.

242
00:16:00,150 --> 00:16:00,750
Here we go.

243
00:16:02,220 --> 00:16:04,230
She that it is working now.

244
00:16:04,560 --> 00:16:08,040
So this is exactly now coming from my server.

245
00:16:08,070 --> 00:16:08,370
Yeah.

246
00:16:08,490 --> 00:16:12,630
The you she did this really working the the multicast.

247
00:16:12,810 --> 00:16:16,410
And here I'm showing this video how to block the pop sheet.

248
00:16:16,860 --> 00:16:20,490
You can see it is working now if you want.

249
00:16:20,490 --> 00:16:22,050
Let's keep this on the background.

250
00:16:22,260 --> 00:16:28,410
If we go to the market across the now, let's check about the IGP group.

251
00:16:28,590 --> 00:16:35,580
So on the IGP group we can see that Internet2 is showing up over here.

252
00:16:35,910 --> 00:16:44,100
239.1.2.3 and if you want, we can go also on the we go to the interface.

253
00:16:45,890 --> 00:16:49,620
And we can see that look, it's an eye to an Internet.

254
00:16:49,620 --> 00:16:51,800
Fonda are following the traffic.

255
00:16:52,790 --> 00:16:55,010
So it's working perfectly.

256
00:16:55,370 --> 00:16:57,790
And I just want to show you something more here.

257
00:16:57,800 --> 00:17:06,920
If we go to the Pentagon and all the A.P. group and this one, she did this the time how 218 seconds.

258
00:17:07,310 --> 00:17:12,500
So that means that this shooter would wait for 200 something seconds.

259
00:17:12,920 --> 00:17:22,820
And then if it doesn't feel the AARP membership from the House, then it will kill the transmission

260
00:17:22,820 --> 00:17:25,780
of the multicast traffic out of his interface.

261
00:17:25,790 --> 00:17:31,880
So this is the time out that I was referring to what number six is on and want number seven close to

262
00:17:31,880 --> 00:17:33,740
be as she at the receiver side.

263
00:17:33,740 --> 00:17:34,820
Does the multicast stop?

264
00:17:35,090 --> 00:17:35,960
So let's have a look.

265
00:17:35,960 --> 00:17:44,750
Now, if we go to the Delta, we can see that there is still 156 seconds to have the timer expire.

266
00:17:44,990 --> 00:17:53,180
Now, if I go to the VRC and I'll just close it, look, this doesn't notify it, so my computer does

267
00:17:53,180 --> 00:17:56,210
not notify the router that he doesn't want the traffic anymore.

268
00:17:56,520 --> 00:18:01,250
And if we look to the interfaces, you see the traffic is still flowing from Ethernet one to Internet

269
00:18:01,250 --> 00:18:01,520
two.

270
00:18:02,150 --> 00:18:02,930
They're still flowers.

271
00:18:02,930 --> 00:18:11,660
So what they're able to do here has to wait this for this 128 seconds to finish until he takes out the

272
00:18:11,660 --> 00:18:12,110
traffic.

273
00:18:12,470 --> 00:18:15,470
And yeah, he doesn't send the multicast anymore.

274
00:18:15,830 --> 00:18:23,180
So like now we have to wait 2 minutes that the router is sending the multicast out of it not to for

275
00:18:23,180 --> 00:18:23,630
nothing.

276
00:18:23,930 --> 00:18:24,310
Right.

277
00:18:24,530 --> 00:18:27,380
And that's something we don't want and that's a solution.

278
00:18:27,380 --> 00:18:30,560
We have it on the IP version two I going to see.

279
00:18:30,800 --> 00:18:34,730
So I'm going to wait here to see this until this is expired.

280
00:18:35,060 --> 00:18:36,350
Let me just make it like this.

281
00:18:36,350 --> 00:18:42,050
I open this here we she see to have 96, I open the interface next to it.

282
00:18:43,880 --> 00:18:48,020
So I just want to be able to see the traffic on the interface.

283
00:18:48,020 --> 00:18:50,660
So that is internet wanted is internet too.

284
00:18:51,380 --> 00:18:57,650
So we have to wait until this is expired and then we are not going to see anymore traffic from Internet

285
00:18:57,650 --> 00:18:59,960
too, after this has been expired.

286
00:19:00,200 --> 00:19:06,080
So let's wait for for this to finish and then we see if it's really going to happen.

287
00:19:06,380 --> 00:19:11,240
So here you can see that is still 15 seconds, 13 seconds, and you see the traffic is still far from

288
00:19:11,240 --> 00:19:12,410
the two interfaces.

289
00:19:12,710 --> 00:19:13,640
Now it's nine.

290
00:19:13,970 --> 00:19:16,370
Let's wait until it's zero and look at Internet two.

291
00:19:16,370 --> 00:19:19,520
What's going to happen here are this traffic one, two, three, two, zero.

292
00:19:22,150 --> 00:19:22,630
Here we go.

293
00:19:22,660 --> 00:19:23,170
Finished?

294
00:19:25,050 --> 00:19:28,840
Now we shall see that internet, too, will not have a lot of gas.

295
00:19:28,860 --> 00:19:32,430
And if you want, we can look here now inside Ethernet WAN.

296
00:19:32,640 --> 00:19:39,660
If we go to the acts, you can see there's a lot of multicast that's increasing y here if we go.

297
00:19:40,930 --> 00:19:43,330
We see that the multicast has stopped.

298
00:19:44,050 --> 00:19:46,570
It's not making anymore multicast traffic.

299
00:19:47,110 --> 00:19:47,520
Why?

300
00:19:47,530 --> 00:19:49,360
Because we said that.

301
00:19:49,480 --> 00:19:53,050
Now this is not doing anymore multicast.

302
00:19:53,380 --> 00:19:54,280
To that interface.

303
00:19:54,280 --> 00:19:56,830
That author was not sending the multicast with that interface.

304
00:19:57,070 --> 00:20:03,310
What you see here as capacity here or as bandwidth is not multicast really is just the normal traffic

305
00:20:03,310 --> 00:20:04,990
that this interface is doing.

306
00:20:05,200 --> 00:20:07,920
Because I'm connected now my it my computer to Ethernet to.

307
00:20:08,320 --> 00:20:13,090
But as for the multicast, you can see that is the multicast that this is doing.

308
00:20:13,090 --> 00:20:19,720
So yeah you see that is the Ethernet while but this is Ethernet two is not doing any multicast anymore.

309
00:20:19,840 --> 00:20:25,360
And if you want to justify that, maybe we can go to tools, we can go to Tosh.

310
00:20:27,870 --> 00:20:28,620
Let's have a look.

311
00:20:29,730 --> 00:20:34,560
I want to put here the destination address those three lines.

312
00:20:35,160 --> 00:20:36,460
But one, two, two, three.

313
00:20:38,070 --> 00:20:39,990
Out of it, select one.

314
00:20:43,050 --> 00:20:48,600
So you can see that is still on Tuesday and I wandered through the SRI.

315
00:20:50,610 --> 00:20:51,930
If we put it on Internet2.

316
00:20:52,860 --> 00:20:55,500
So Internet2 does not have any traffic anymore.

317
00:20:56,040 --> 00:20:57,750
239.122.3.

318
00:20:57,840 --> 00:20:58,920
What number seven has done?

319
00:20:58,920 --> 00:21:04,740
And with this path I have showed you the first slab for multicast using the IGP version one, you can

320
00:21:04,740 --> 00:21:05,940
see it's not very difficult.

321
00:21:05,940 --> 00:21:10,800
You only need to understand the concept and then once you do that, configuration is very simple on

322
00:21:10,800 --> 00:21:11,790
the microcontroller.

323
00:21:12,180 --> 00:21:15,840
So I hope that this lecture was informative for you, and I'll see you in the upcoming lecture.
