I doubt that this might have that here again.
So we have to start now, a new section and then this section.
I have to speak about them, which is the multicast routing protocol.
So say that you have in your network more than one there, because up to now all the layers that we
have done, just we met one router, we connected a streaming server to us to a streaming receiver,
and we made that the multicast working.
But what if we have between those two devices, the streaming server and the receiver?
We have many routers.
So how the multicast will work.
So that's why we call it the Layer three multicast.
So in this section, I'm going to speak about PEM, which is the mechanism allowing the multicast to
flow on the legacy when you have more than one router.
And I'm going first to make the explanation to explain to you about BIM, all the details that you need
to know about them.
Then I will be doing Labs to show you all the details, how you can configure them to work correctly
on the mike, the crafter.
So this is all what we are going to do in this session.
If you are ready, let's go directly.
I start with the first lecture, which is the explanation about the BIM.
