1 00:00:00,060 --> 00:00:00,510 Hi, Daddy. 2 00:00:00,510 --> 00:00:01,650 This might have that here again. Technet24.ir 3 00:00:01,920 --> 00:00:07,710 So we have seen in the beginning of this course, we spoke about the ICMP snooping and we said that 4 00:00:07,710 --> 00:00:12,570 once you have the switch on your network and of course we always have switches in our network, then 5 00:00:12,570 --> 00:00:19,380 the multicast on the switch, if you don't have the IP snooping, then the multicast will be growing 6 00:00:19,380 --> 00:00:25,050 out of all the interfaces of the switch, even though that the computer doesn't want that these multicast 7 00:00:25,050 --> 00:00:29,790 that will receive it and multicast on the network is not very good because that's your multicast. 8 00:00:30,210 --> 00:00:36,750 So what you can do is that we can enable IP snooping and with the IP snooping then the multicast would 9 00:00:36,750 --> 00:00:39,440 go only to us that want the multicast. 10 00:00:39,450 --> 00:00:40,920 It doesn't go to everyone. 11 00:00:41,310 --> 00:00:47,250 I'm going to show you how this mechanism happens, and then I'm going to do a lab to show you how this 12 00:00:47,400 --> 00:00:48,360 is going to work. 13 00:00:48,360 --> 00:00:54,840 On the microdroplets, I'm going to use one microcontroller to make the streaming of the multicast, 14 00:00:55,050 --> 00:01:01,800 and I put a microchip switch and then I put two or three host and then we'll see how the idea of being 15 00:01:01,800 --> 00:01:02,280 with work. 16 00:01:02,730 --> 00:01:04,890 So this is what we are going to do in this section. 17 00:01:04,890 --> 00:01:10,140 If you are ready, let's go directly to the lecture, which is actually only one lecture making the 18 00:01:10,140 --> 00:01:11,970 explanation and the lab. 19 00:01:11,970 --> 00:01:15,150 And this is going to be the last lecture of this course. 20 00:01:15,360 --> 00:01:16,680 So see you in the upcoming lecture.
