1 00:00:00,030 --> 00:00:00,360 Hi there. 2 00:00:00,360 --> 00:00:01,530 That is my dad here again. 3 00:00:01,530 --> 00:00:07,620 So this is going to be a fun stop because we already know all the details and you see that how we can 4 00:00:07,620 --> 00:00:13,770 configure the theme with the PSR and the R.P candidates and it's going to work without any problem. 5 00:00:14,160 --> 00:00:15,570 So we are still on the same scenario. 6 00:00:15,570 --> 00:00:20,700 All the IP addresses aside here, we do have to Rothert I want this alter to be the BSR. 7 00:00:20,700 --> 00:00:28,740 So this one would be propagating above the list of IP on their groups and who is going to be the RB? 8 00:00:29,580 --> 00:00:34,470 Well, actually, he's going to be the RB of the group, which is crucial 9.12 to the stream. 9 00:00:35,190 --> 00:00:36,180 So what's going to happen? 10 00:00:36,180 --> 00:00:41,700 We have to enable here bin and once we do that, then we will see directly that the best message will 11 00:00:41,700 --> 00:00:50,030 be sent to him and thereafter he will see the best shot and he will have the a rendezvous point shown 12 00:00:50,040 --> 00:00:52,080 up on roster right away. 13 00:00:52,530 --> 00:00:59,010 So what we need to do, we have to enable PEM here on the interfaces, we have to enable PEM here on 14 00:00:59,010 --> 00:01:05,670 the interfaces that we do all the work here we have to do the BSR candidate, the RB candidate, and 15 00:01:05,670 --> 00:01:12,600 of course we have to make this one as the RB, so we just have to make it as the RB and that's it. 16 00:01:12,600 --> 00:01:19,320 And then you will see that it will propagate this to after two and out of two will be able to see that 17 00:01:19,320 --> 00:01:21,450 from the bootstrap from the BSR. 18 00:01:22,050 --> 00:01:23,850 So let's go directly and start with the lab. 19 00:01:23,910 --> 00:01:25,920 So we are on router one now. 20 00:01:26,160 --> 00:01:31,170 Again, what we need to do, we just have to go to routing bin the from here. 21 00:01:31,170 --> 00:01:36,990 Let's first put it in that one and then it in a two. 22 00:01:37,230 --> 00:01:46,650 And from now we go to out of to and from here we have to go to routing them and we put it in at one. 23 00:01:48,370 --> 00:01:50,410 And we put it in a tool. 24 00:01:53,110 --> 00:01:55,770 So now we should have the neighbors. 25 00:01:55,780 --> 00:01:56,980 So that's already done. 26 00:01:57,220 --> 00:01:59,620 Rather, we don't need to do anything anymore. 27 00:02:00,100 --> 00:02:01,750 Let me just put the picture so you can follow. 28 00:02:01,960 --> 00:02:04,450 So rather to rule, not going to do anything over there. 29 00:02:04,510 --> 00:02:06,100 All the work will happen on another one. 30 00:02:06,820 --> 00:02:09,310 So first we have to say that rather one is the IP. 31 00:02:09,760 --> 00:02:12,220 So we just make as we always do. 32 00:02:12,730 --> 00:02:16,210 We have to show the addresses one and two and say the one to the one. 33 00:02:16,270 --> 00:02:21,190 And we have to put the group here, which is loosely defined as 0.122.3. 34 00:02:21,250 --> 00:02:21,580 Right. 35 00:02:23,040 --> 00:02:27,780 And then, okay, now we have done the RB, we have to do the BSR and the candidate. 36 00:02:28,110 --> 00:02:29,140 That's our candidate. 37 00:02:29,160 --> 00:02:34,740 That means we have to say the multicast or the BSR message. 38 00:02:35,010 --> 00:02:41,370 That will have to be sent out of which interface you see on the picture that the right one is connected 39 00:02:41,370 --> 00:02:42,170 to on Internet2. 40 00:02:42,420 --> 00:02:45,110 So I will leave all the multicast zone. 41 00:02:45,210 --> 00:02:51,280 So this is 224000 slash for that means all the multicast, the others. 42 00:02:51,560 --> 00:02:53,430 And now I have to say, here is an actor. 43 00:02:53,760 --> 00:02:54,210 That's it. 44 00:02:55,020 --> 00:02:58,600 Now, the last thing I want to do is to make the RB candidate show. 45 00:02:58,620 --> 00:03:05,190 I want to say that this router wants to be the RB of 239.122.3. 46 00:03:05,670 --> 00:03:20,430 So I will say here that I want to be the RB of 239.122.3 slash 32 and I will send it out of Ethernet 47 00:03:20,430 --> 00:03:22,080 two, which is connected to that of two. 48 00:03:23,310 --> 00:03:24,690 That's all what you need to do. 49 00:03:25,110 --> 00:03:28,740 Now, let's have a look what's going to happen on Rocket Two. 50 00:03:28,830 --> 00:03:31,440 So we go to other two now and let's have a look. 51 00:03:31,440 --> 00:03:34,110 We go to routing, we go to Pim first. 52 00:03:34,110 --> 00:03:35,050 Let's check the BSR. 53 00:03:35,070 --> 00:03:35,550 Here we go. 54 00:03:35,850 --> 00:03:39,030 He has discovered that there is a BSR, which is this IP address. 55 00:03:39,210 --> 00:03:39,780 Very good. 56 00:03:40,140 --> 00:03:42,150 So he knows about the BSR. 57 00:03:42,870 --> 00:03:45,420 Okay, let's check if he knows about the IP. 58 00:03:45,480 --> 00:03:46,140 Here we go. 59 00:03:46,260 --> 00:03:51,470 You know that there is an IP now, which is to show 9.1.2.3 on this address. 60 00:03:52,530 --> 00:03:58,230 Now you can do the multicast and it is going to work without any problem because yeah, that is already 61 00:03:58,230 --> 00:03:58,500 there. 62 00:03:58,500 --> 00:03:59,670 You can see the Amber Hub. 63 00:04:00,570 --> 00:04:03,900 That is the table over here. 64 00:04:04,350 --> 00:04:06,550 Also on routing, the one we can see the emirate. 65 00:04:07,290 --> 00:04:09,570 So yeah, the multicast is now going to work. 66 00:04:09,820 --> 00:04:15,330 And you see, we didn't have to go to every router and we just made it all know on router. 67 00:04:15,330 --> 00:04:20,790 And it is going to look again to remember, do not forget to use the unique routing protocol. 68 00:04:21,120 --> 00:04:23,460 Now what I did are just in the background. 69 00:04:23,460 --> 00:04:24,870 I just enabled hpf. 70 00:04:25,320 --> 00:04:28,840 So I just said I want to enable OSPF, which is a unique consortium protocol. 71 00:04:28,860 --> 00:04:30,090 I made it on Rafter one. 72 00:04:30,870 --> 00:04:34,070 You can see I just had make it on all interfaces. 73 00:04:34,080 --> 00:04:34,980 That's okay for now. 74 00:04:35,280 --> 00:04:38,660 And I made it also on router two. 75 00:04:39,930 --> 00:04:42,810 Of course, if you have a small network, you can use the socket grub. 76 00:04:43,020 --> 00:04:48,690 But I advise when you have a big network, you should have the routing protocol, that cross graph running, 77 00:04:48,960 --> 00:04:52,460 because in this case they need to be able to reach to the r.p. 78 00:04:52,470 --> 00:04:59,040 And if you don't have a routing protocol enabled, how can they know how to react to the IP of the RB? 79 00:04:59,640 --> 00:05:05,120 So this is all what I wanted to show you in this lecture I saw about the pin BCR. 80 00:05:05,460 --> 00:05:08,070 So I hope that this LA was informative for you. 81 00:05:08,280 --> 00:05:09,990 And I'll show you in the upcoming lecture.
