1 00:00:00,000 --> 00:00:03,318 [AUDIO LOGO] 2 00:00:03,318 --> 00:00:08,260 3 00:00:08,260 --> 00:00:12,680 Hello, and welcome to Implementing IP Multicast. 4 00:00:12,680 --> 00:00:14,990 In this skill, we're finally going 5 00:00:14,990 --> 00:00:18,890 to jump onto the command line and implement this multicast 6 00:00:18,890 --> 00:00:21,020 that we've been talking about in all 7 00:00:21,020 --> 00:00:23,270 these previous multicast skills. 8 00:00:23,270 --> 00:00:27,060 Specifically, we're going to be looking at PIM sparse mode. 9 00:00:27,060 --> 00:00:31,280 So our first step will be to enable PIM sparse mode 10 00:00:31,280 --> 00:00:35,420 on the routers and on the appropriate interfaces. 11 00:00:35,420 --> 00:00:37,770 And, of course, as we configure that, 12 00:00:37,770 --> 00:00:41,360 we're also going to want to verify our PIM neighborships. 13 00:00:41,360 --> 00:00:45,020 Then we have to configure the rendezvous point. 14 00:00:45,020 --> 00:00:48,740 In this case, we're simply going to do a static RP 15 00:00:48,740 --> 00:00:50,000 configuration. 16 00:00:50,000 --> 00:00:53,240 We'll be looking at other options for the RP 17 00:00:53,240 --> 00:00:55,130 in a future skill. 18 00:00:55,130 --> 00:00:57,260 Then we're going to spend a little bit of time 19 00:00:57,260 --> 00:01:01,460 examining IGMP, which is the protocol used 20 00:01:01,460 --> 00:01:04,849 between the receiver and the last hop router, 21 00:01:04,849 --> 00:01:08,820 so the last hop router knows which groups the client 22 00:01:08,820 --> 00:01:10,860 is interested in receiving. 23 00:01:10,860 --> 00:01:15,660 Once we do that, we will start up an actual receiver 24 00:01:15,660 --> 00:01:20,520 so that it will build the shared tree or the star comma G tree. 25 00:01:20,520 --> 00:01:22,770 We'll, of course, examine that tree, 26 00:01:22,770 --> 00:01:25,200 see how it gets built to the rendezvous point, 27 00:01:25,200 --> 00:01:30,450 and then we will fire up a source have that traffic make 28 00:01:30,450 --> 00:01:31,920 it to the receiver. 29 00:01:31,920 --> 00:01:36,030 And then we can examine the source tree or the shortest 30 00:01:36,030 --> 00:01:37,210 path tree. 31 00:01:37,210 --> 00:01:40,170 So, as you can see, we have a lot to configure and a lot 32 00:01:40,170 --> 00:01:41,200 to look at. 33 00:01:41,200 --> 00:01:43,540 Let's go ahead and jump in and get started. 34 00:01:43,540 --> 00:01:46,970 I'll see you in the next video. 35 00:01:46,970 --> 00:01:50,000
