Alright, let's talk a little bit now and we'll come back by the way, the IEEE 8021 D right? thing are so broken. Okay, now this is the the one that mostly everybody uses. We know that SDP is to prevent switching loops you already know that. And like I said earlier switches by nature, they four frames non stop. That's why Cisco came up with that 8021 D to prevent switching loops.

Now breaking this now, as far as the 8021 D, the most recent version, we're in 2017. The most recent version of it was 2004. That was 13 years ago. Okay. So yeah, that's an old protocol. All right, all ports, others which must be interesting there 14 in order for this to take effect, right, all ports, all of the route, switch.

We'll talk about how that happens. Right must be in designated 40. In a link single item, a portion of the things in a switch that do connect the line segment must be placed in forwarding mode, meaning all the other ports are set to 40 designated switches, the ports facing the root bridge are ports. And we'll talk about that and we'll look at a visualization of it. That way you understand better what's going on because this is saying a couple couple things about it was telling you designated ports, ports, 14 ports, all that stuff, once again to the election process of STP was you bring it down? Okay.

We'll go ahead and you'll get a better understanding of that, which of course will work especially when you go to the visualization on it. The configuration on STP will be the next section and we'll configure STP in the next section. Okay, but in this one, he's going to talk he's going to talk about it. Okay, let's go to one the, you know, the latest version was an arrow was in 2004 yesterday. years ago, we don't want to use that. Okay, so we'll probably be changing and the type of spanning tree that we're using.

Right But you know, it has its benefits. Yes, it benefits but we'll, we'll see what happens when we get there. See you then.
