1
00:00:00,150 --> 00:00:01,860
I doubt that this might have that here again.

2
00:00:02,220 --> 00:00:05,280
So we have to start now, a new section and then this section.

3
00:00:05,280 --> 00:00:09,330
I have to speak about them, which is the multicast routing protocol.

4
00:00:09,660 --> 00:00:14,340
So say that you have in your network more than one there, because up to now all the layers that we

5
00:00:14,340 --> 00:00:19,950
have done, just we met one router, we connected a streaming server to us to a streaming receiver,

6
00:00:20,280 --> 00:00:22,830
and we made that the multicast working.

7
00:00:23,130 --> 00:00:28,040
But what if we have between those two devices, the streaming server and the receiver?

8
00:00:28,230 --> 00:00:29,520
We have many routers.

9
00:00:29,790 --> 00:00:31,770
So how the multicast will work.

10
00:00:31,980 --> 00:00:34,890
So that's why we call it the Layer three multicast.

11
00:00:35,310 --> 00:00:41,610
So in this section, I'm going to speak about PEM, which is the mechanism allowing the multicast to

12
00:00:41,610 --> 00:00:45,030
flow on the legacy when you have more than one router.

13
00:00:45,330 --> 00:00:51,510
And I'm going first to make the explanation to explain to you about BIM, all the details that you need

14
00:00:51,510 --> 00:00:52,230
to know about them.

15
00:00:52,410 --> 00:00:59,100
Then I will be doing Labs to show you all the details, how you can configure them to work correctly

16
00:00:59,100 --> 00:01:00,220
on the mike, the crafter.

17
00:01:00,240 --> 00:01:02,430
So this is all what we are going to do in this session.

18
00:01:02,700 --> 00:01:04,110
If you are ready, let's go directly.

19
00:01:04,110 --> 00:01:08,560
I start with the first lecture, which is the explanation about the BIM.
