1 00:00:00,030 --> 00:00:01,470 I know that this might have that here again. 2 00:00:01,470 --> 00:00:06,470 So in this lecture, I have to show you the explanation about what is the agent shopping? 3 00:00:06,630 --> 00:00:11,520 And then I'm going to do a lab sugar lab, as you can see here is about six months before I started 4 00:00:11,520 --> 00:00:12,300 doing those points. 5 00:00:12,300 --> 00:00:16,020 Let's go to the explanation to explain what this exactly Asia is doing. 6 00:00:16,320 --> 00:00:18,750 And then I will come back to the box and start doing that. 7 00:00:18,810 --> 00:00:23,280 So I am looking at something that we already have seen at the beginning of this course. 8 00:00:23,610 --> 00:00:28,170 So say that we have a switch here connected to this shot, that this shot that is connected to this 9 00:00:28,170 --> 00:00:29,460 service streaming the video. 10 00:00:30,270 --> 00:00:32,880 Now, one day multicast stream arrived to the switch. 11 00:00:33,090 --> 00:00:39,150 If you don't have the IGP snooping, then what this watch would do, it was send it out of all its ports. 12 00:00:39,150 --> 00:00:39,480 Why? 13 00:00:39,870 --> 00:00:42,900 Because we will see in a moment why this behavior is happening. 14 00:00:43,410 --> 00:00:48,690 And if you already think of it, maybe you will have to say that this is something to do with the Mac 15 00:00:48,690 --> 00:00:51,490 addressing because the switch doesn't understand IP. 16 00:00:51,540 --> 00:00:52,830 You understand Mac address. 17 00:00:53,340 --> 00:00:59,370 While if you have the IGP shopping then you will see that the multicast would be coming to the switch. 18 00:00:59,670 --> 00:01:01,710 The switch will send it only to the receivers. 19 00:01:01,710 --> 00:01:05,250 That means to the host that want them off the cache which is this one. 20 00:01:05,250 --> 00:01:05,670 This one. 21 00:01:05,880 --> 00:01:07,080 This one is a non receiver. 22 00:01:07,080 --> 00:01:07,800 He will not get it. 23 00:01:08,040 --> 00:01:11,880 But over here this one is Anonymous Shiva, but he's still got it. 24 00:01:12,210 --> 00:01:13,710 So let's see the mechanism. 25 00:01:13,710 --> 00:01:17,760 What happens when we have the agent being enabled on the micro switch? 26 00:01:17,850 --> 00:01:24,210 So if we go a little bit on the under layer and we see what's happening here, one, the streaming is 27 00:01:24,210 --> 00:01:25,290 coming to the router. 28 00:01:25,290 --> 00:01:30,270 The oracle will say that the destination is 239.1.2.3, which we already know. 29 00:01:30,270 --> 00:01:31,440 That's the Martha Garcia group. 30 00:01:31,950 --> 00:01:34,080 And remember the destination Mac address. 31 00:01:34,080 --> 00:01:38,820 That's something I have expanded beginning of this course that the multicast will have addition of Mac 32 00:01:38,820 --> 00:01:41,330 either starting by 01005e. 33 00:01:42,480 --> 00:01:44,130 Now this will come to the switch. 34 00:01:44,130 --> 00:01:47,760 Normally the switch he opened his container or the Mac address table. 35 00:01:48,150 --> 00:01:48,990 And who was she? 36 00:01:49,680 --> 00:01:53,730 The destination Mac address is 01005 is, of course. 37 00:01:54,450 --> 00:01:56,670 And who will check to which port he has to show that? 38 00:01:56,670 --> 00:02:01,980 But this Mac address is none of those Mac addresses that are on the computer. 39 00:02:02,880 --> 00:02:08,700 Then here the switch will say, all right, that's I don't know what is the destination, Mac. 40 00:02:08,700 --> 00:02:09,030 Others. 41 00:02:09,180 --> 00:02:12,740 So what I'm going to do, I'm going to send it out of all my pulse. 42 00:02:13,230 --> 00:02:18,480 But of course it doesn't send it back like this, but only to send it from all the ports, not but not 43 00:02:18,480 --> 00:02:20,730 from the port that has received the Macintosh from. 44 00:02:21,570 --> 00:02:27,060 So you can see the switches saying, I have no clue about the destination Mac address, so I'll send 45 00:02:27,060 --> 00:02:28,650 the traffic out of all my thoughts. 46 00:02:29,580 --> 00:02:35,880 So this is happening if you don't have the IGP stopping now, if we have the IGP stopping, what's going 47 00:02:35,880 --> 00:02:36,450 to happen? 48 00:02:36,930 --> 00:02:38,520 Remember the computer one? 49 00:02:38,520 --> 00:02:43,950 He'll want the multicast, then he has to communicate to the router and it was send. 50 00:02:43,980 --> 00:02:51,180 We had the membership report so we send the membership report to the rotation that I want the multicast. 51 00:02:51,570 --> 00:02:56,970 So once he sent this membership report and we have IGP snooping enabled on the switch, the switch will 52 00:02:56,970 --> 00:03:00,990 listen to that membership report, which is the IGP membership report. 53 00:03:01,680 --> 00:03:08,310 And then it will say, okay, he will add on his my other stable that this computer he wants to multicast 54 00:03:08,550 --> 00:03:11,040 and he will say it's connected to that box. 55 00:03:11,040 --> 00:03:16,590 So once the multicast arrive to the switch, the switch knows that I know that this computer wanted 56 00:03:16,740 --> 00:03:23,600 so he can follow on it once this computer stop his request for the month, just like closing the reality 57 00:03:23,790 --> 00:03:28,170 media, for example, then this entry that the switch has put it, he will take it out. 58 00:03:28,530 --> 00:03:30,750 So you can see the switch becomes smarter. 59 00:03:30,930 --> 00:03:35,930 So you see that the traffic will be flowing of the multicast like this, but those two will not receive 60 00:03:35,950 --> 00:03:40,080 it or do not send it out from all this support like we had in this case. 61 00:03:40,260 --> 00:03:42,330 And that's something which is much better. 62 00:03:42,450 --> 00:03:45,060 Why do we use the ICMP snooping? 63 00:03:45,510 --> 00:03:47,010 So now we understand. 64 00:03:47,010 --> 00:03:48,450 What is the IGP snooping? 65 00:03:48,600 --> 00:03:50,550 Let's see, what is the love scenario? 66 00:03:50,640 --> 00:03:52,380 Now my love show is as following. 67 00:03:52,410 --> 00:03:54,000 I have this streaming server. 68 00:03:54,270 --> 00:03:55,050 It is the router. 69 00:03:55,170 --> 00:03:59,940 Everything is already configured here so their output is able to stream them onto us. 70 00:03:59,940 --> 00:04:01,560 We're going to focus on this switch. 71 00:04:02,040 --> 00:04:08,010 So what I'm going to do, I have to make this switch as a switch because it's actually a router microcosm. 72 00:04:08,010 --> 00:04:14,490 But I will make it as a switch by putting all those ports into that 1 to 3 inside the bridge interface. 73 00:04:15,120 --> 00:04:17,700 And then we are going to make the multicast on two computers. 74 00:04:18,600 --> 00:04:24,720 We'll see that if they will be able to get the multicast video from this streaming server and then I'm 75 00:04:24,720 --> 00:04:31,530 going to stop the multicast request from this computer, that means I will just close to ABC. 76 00:04:31,890 --> 00:04:37,860 You will see if we don't have an option that the multicast traffic will keep flowing on to that interface. 77 00:04:37,860 --> 00:04:42,120 Of course it's relevant to this one because this one I want them to guess, but this one doesn't want 78 00:04:42,120 --> 00:04:42,300 it. 79 00:04:42,300 --> 00:04:43,260 It will keep flowing. 80 00:04:44,130 --> 00:04:50,400 So what I'm going to do then I have to enable the IGP stopping and then make multicast again here so 81 00:04:50,400 --> 00:04:51,390 the traffic will be flowing. 82 00:04:51,390 --> 00:04:55,920 And then I have to stop the request for the multicast as she directly. 83 00:04:56,310 --> 00:04:59,460 Then because we have IP snooping enabled then. 84 00:04:59,700 --> 00:05:04,920 It will not anymore flow the traffic of the markaz to this computer, but it will keep sending it to 85 00:05:05,220 --> 00:05:06,150 that computer. 86 00:05:06,630 --> 00:05:08,550 So that is what we are going to do in this lab. 87 00:05:08,580 --> 00:05:10,620 Let's go now back to the Porsche stock going down. 88 00:05:10,770 --> 00:05:12,030 What number one or switch one? 89 00:05:12,030 --> 00:05:14,070 Put it in at one, two or three, an average. 90 00:05:14,610 --> 00:05:18,140 So again, the configuration on the rotor is already done for the Marcos. 91 00:05:18,150 --> 00:05:19,680 You already know how to do that. 92 00:05:19,680 --> 00:05:21,030 So I'm not going to do it anymore. 93 00:05:21,390 --> 00:05:23,430 I'm going to focus working on the switch now. 94 00:05:23,970 --> 00:05:29,910 So let's go to the switch and we have to make it a switch because that's a problem now. 95 00:05:30,840 --> 00:05:36,030 So all you need to do is just create a bridge interface and this bridge interface. 96 00:05:36,030 --> 00:05:37,470 I'm going to put it in that one. 97 00:05:38,850 --> 00:05:40,750 I'm going to put it in a two. 98 00:05:41,550 --> 00:05:45,510 It may get disconnected because I'm connected to it or not to now. 99 00:05:46,440 --> 00:05:47,130 Here we go. 100 00:05:47,850 --> 00:05:48,660 We connect again. 101 00:05:48,660 --> 00:05:49,260 No problem. 102 00:05:50,330 --> 00:05:57,860 And I'm going to put inside this great Ethan story, which is connected to the second computer. 103 00:05:58,250 --> 00:06:01,970 So now we have this, which, of course, should be careful. 104 00:06:02,210 --> 00:06:10,310 Remember to have the horror of law check, because on the back of the frame, they would go to the switch 105 00:06:10,310 --> 00:06:15,530 chip, which is inside the microchip router without going through the chip. 106 00:06:15,530 --> 00:06:19,190 Used to be able to send the frames from one to another. 107 00:06:19,700 --> 00:06:20,060 All right. 108 00:06:20,060 --> 00:06:20,390 Very good. 109 00:06:20,400 --> 00:06:22,160 So now did this already done? 110 00:06:22,340 --> 00:06:27,500 Well, number one is not block number to enable a streaming on the server and it everywhere as she client 111 00:06:27,500 --> 00:06:27,830 on PC. 112 00:06:27,830 --> 00:06:34,490 You want to be sure to just to see if it's going to work so I'm going to start device is streaming on 113 00:06:34,490 --> 00:06:35,180 the server. 114 00:06:36,020 --> 00:06:42,980 So this has started I will go to my computer which is this one now. 115 00:06:43,520 --> 00:06:47,960 So I will go to PC one and I will open. 116 00:06:49,640 --> 00:06:50,720 The streaming. 117 00:06:52,950 --> 00:06:54,810 And request it from me that you want. 118 00:06:54,990 --> 00:06:56,490 So it is working now. 119 00:06:56,730 --> 00:07:03,000 I would go to the other computer, which you don't see it, but I will show you now that there would 120 00:07:03,000 --> 00:07:05,010 be traffic happening. 121 00:07:05,580 --> 00:07:07,620 So even though that you don't see it. 122 00:07:07,620 --> 00:07:08,430 But that's fine. 123 00:07:10,290 --> 00:07:11,590 I'll show it to you in a moment. 124 00:07:11,610 --> 00:07:14,800 So that is the second computer beside you. 125 00:07:15,360 --> 00:07:19,470 So I would put the link of UDP. 126 00:07:21,000 --> 00:07:22,190 And it is working. 127 00:07:22,200 --> 00:07:27,690 So now the Velshi is working on both computers. 128 00:07:27,960 --> 00:07:34,560 And if you want, we can go to the switch to the interfaces. 129 00:07:35,730 --> 00:07:36,390 And here we go. 130 00:07:36,400 --> 00:07:40,860 You can see these are the graphics, these are multicast traffic on Internet2. 131 00:07:41,400 --> 00:07:45,030 You can see we are checking now the the ABCs. 132 00:07:45,570 --> 00:07:52,230 So this is the three X is increasing that is to PC one and that is to push it to the x is increasing. 133 00:07:52,650 --> 00:07:54,750 So now it's working without any problem. 134 00:07:54,750 --> 00:07:56,790 Let's see what we have to do now. 135 00:07:56,970 --> 00:07:59,070 What number two is not working obviously close. 136 00:07:59,070 --> 00:08:02,970 We are C player on PC two is ethernet switch to passing traffic. 137 00:08:03,300 --> 00:08:05,580 So my PC two, I will close now. 138 00:08:05,580 --> 00:08:07,860 VELSHI So I just closed it. 139 00:08:08,190 --> 00:08:09,180 Let's go to the roster. 140 00:08:10,050 --> 00:08:11,430 Let's go to the interfaces. 141 00:08:12,630 --> 00:08:19,650 Look, I closed it but still the the multicast especially on international you can see so if we can 142 00:08:19,650 --> 00:08:26,940 go to UTX so you can see it's still sun y because we do not have AGM be snooping enabled. 143 00:08:26,940 --> 00:08:29,250 And that's something I can show to you here on the bridge. 144 00:08:29,250 --> 00:08:32,910 Look, I shall be snooping is not checked, so it's not enabled. 145 00:08:33,180 --> 00:08:35,790 So now we have to see how to solve this problem. 146 00:08:36,060 --> 00:08:37,770 Point number three is not path number four. 147 00:08:37,770 --> 00:08:40,170 Enable agent be snooping on the bridge globally. 148 00:08:40,680 --> 00:08:46,860 So let's go to the bridge now on the switch and we have to enable Asia AMP is looking we enable it globally 149 00:08:47,160 --> 00:08:51,870 on the bridge interface and then I will say here. 150 00:08:51,870 --> 00:08:52,320 Okay. 151 00:08:53,640 --> 00:08:54,120 Very good. 152 00:08:54,420 --> 00:08:55,770 So that's what we need to do. 153 00:08:55,980 --> 00:08:58,020 Bulk number four is not block number five open. 154 00:08:58,020 --> 00:09:04,410 If you are showing this, you two then close it of the is the multicast traffic still flight itinerary? 155 00:09:04,650 --> 00:09:06,610 Let's check what we have now on the interface. 156 00:09:06,630 --> 00:09:11,310 You can see that internationally it now is not making any multicast traffic. 157 00:09:11,310 --> 00:09:17,060 I will enable multicast on PC two and we should see. 158 00:09:17,070 --> 00:09:17,610 Here we go. 159 00:09:17,610 --> 00:09:23,340 The multicast has started flowing and I can see it in front of me is working also on my computer, which 160 00:09:23,490 --> 00:09:26,760 is why you can see that multicast is still working. 161 00:09:26,760 --> 00:09:28,170 So the streaming is still working. 162 00:09:28,680 --> 00:09:32,190 So now what I need to do, I have to close reality on the computer. 163 00:09:32,190 --> 00:09:34,200 So I have the IGP still being enabled. 164 00:09:34,560 --> 00:09:38,430 So once I close VELSHI Here, let's have a look what's going to happen. 165 00:09:41,820 --> 00:09:46,650 You can see directly, it has dropped down to 24 grams for a second here. 166 00:09:46,660 --> 00:09:53,010 The multicast is still working because it's going to my computer PC one but mission two is not the making 167 00:09:53,310 --> 00:09:55,500 anymore or requesting for a month across traffic. 168 00:09:55,680 --> 00:09:59,280 So that means the traffic of the month cars will not go out from the interface. 169 00:09:59,280 --> 00:10:00,840 Ethan That's free to the computer. 170 00:10:01,020 --> 00:10:04,050 So you see how nice it is to do the Asian piece looping. 171 00:10:04,350 --> 00:10:05,970 And it's only one comment you can see. 172 00:10:05,970 --> 00:10:12,810 Just go inside of it and then you can go to here and an enabler of course, when you enable that, you 173 00:10:12,810 --> 00:10:15,960 have here some information that you can play with. 174 00:10:16,410 --> 00:10:21,360 So I highly advise that you don't change anything over here, don't play with that. 175 00:10:21,360 --> 00:10:25,920 But if you are an expert and you want to make some changes, you can do so. 176 00:10:26,430 --> 00:10:31,290 And to mention something that I mean works only on the ICMP version too. 177 00:10:31,680 --> 00:10:38,130 So be careful on the router when you make the multicast to work, be careful to choose Agent P version 178 00:10:38,130 --> 00:10:39,270 two and not version one. 179 00:10:39,270 --> 00:10:45,450 Because remember I GAAP version one does not send membership report, which is what the switch is based 180 00:10:45,450 --> 00:10:51,990 on to be able to know where he has to send the traffic one that is a communication between the computers 181 00:10:52,140 --> 00:10:53,580 and the router. 182 00:10:53,760 --> 00:10:54,990 Port number five is Don. 183 00:10:54,990 --> 00:11:01,260 And then the last point of this lab and for the whole course is that you go to the switch and check 184 00:11:01,260 --> 00:11:05,790 the two following comments and let's check for Interface Bridge and the P print. 185 00:11:06,090 --> 00:11:08,040 So that's something also you can see it over here. 186 00:11:09,690 --> 00:11:12,390 So over here you can see the is the MVP. 187 00:11:13,050 --> 00:11:22,170 So you can see that for example the the group multicast to Schneider wanted to the three is on the interface 188 00:11:22,170 --> 00:11:27,960 Ethernet a tool which is to the computer and that's something you can see it over here. 189 00:11:27,960 --> 00:11:29,730 You can also make it on the command. 190 00:11:30,300 --> 00:11:39,930 So the command wizard is to be interface bridge, handprint interface bridge and the p print 191 00:11:42,840 --> 00:11:45,120 have the the actually print. 192 00:11:46,290 --> 00:11:49,230 So here that is the same result that we have seen. 193 00:11:49,590 --> 00:11:56,370 And also there is another one which is I like it interface Bridgeport Monitor with an interface, bridge 194 00:11:57,090 --> 00:11:59,940 or monitor. 195 00:12:01,440 --> 00:12:10,860 And when you open the bracket and you say, so what this will show you, it will say that this switch 196 00:12:10,860 --> 00:12:14,070 is connected to a multicast rather on the interface. 197 00:12:14,070 --> 00:12:19,080 You see Ethernet one show on ether, not one this which is connected to multicast, but on Ethernet 198 00:12:19,080 --> 00:12:19,350 too. 199 00:12:19,350 --> 00:12:23,310 And Ethan Asri is not connected to a multicast rather. 200 00:12:23,460 --> 00:12:27,060 So that's something also you can check it what number six is done. 201 00:12:27,060 --> 00:12:29,310 And with this point, I have finished the whole course. 202 00:12:29,310 --> 00:12:34,670 I hope that that the course was easy for you and you could understand how it you to run multicast on 203 00:12:34,690 --> 00:12:34,860 like. 204 00:12:34,990 --> 00:12:40,470 Yes it's not very difficult if you only understand the concept configuration or making it for multicast 205 00:12:40,500 --> 00:12:42,600 is straightforward is not very difficult. 206 00:12:42,990 --> 00:12:46,760 Like in a Cisco, they have plenty of more things you can do and you have to do everything on common 207 00:12:46,770 --> 00:12:53,310 line or I think that just gave us what is essential to be able to run multicast and it's working perfectly. 208 00:12:53,820 --> 00:13:02,070 So if you like my way of teaching, please do not forget to let all people know about my work that I 209 00:13:02,070 --> 00:13:02,340 do. 210 00:13:02,520 --> 00:13:06,810 I would appreciate to be able to let other people join my courses. 211 00:13:07,140 --> 00:13:11,940 I will leave for you my contact details so I will leave for you my email address. 212 00:13:12,300 --> 00:13:18,690 I will leave you for you, my WhatsApp number and of course my website which is my network training 213 00:13:18,690 --> 00:13:19,080 dot com. 214 00:13:19,080 --> 00:13:26,910 When I watched all the courses that I have also for you all my social contact details, my Facebook, 215 00:13:27,120 --> 00:13:33,780 my YouTube channel that I highly advise you to join me because I host always a lot of videos over there 216 00:13:34,170 --> 00:13:36,180 and my Twitter as well. 217 00:13:36,540 --> 00:13:41,580 So yeah, I thank you very much for the time that you have spent with me in this course. 218 00:13:41,970 --> 00:13:47,430 I appreciate that you have bought this course to be able to understand multicast. 219 00:13:47,700 --> 00:13:53,490 Thank you very much for the time that you have spent with me and I hope to see you in some other courses. 220 00:13:53,490 --> 00:13:54,660 Thank you and bye bye.
