Alrighty, VTP synchronization. Now, when we started this, I said that that really goes along with advertisements, right? Because they're gonna synchronize with each other because we're setting the policy domain, and they're going to send advertisements. So they have to synchronize when a switch receives a BGP advertisement with a revision number, oh, that is a higher that's higher than the value stored locally, it will consider to be new information. I told you this, right. Okay.

This is what you really need to know. Here. It says how it overwrites right here, how to change the revision number and reset it again. So you got two ways of doing it. And, again, you'll have access to these presentations. So you got this information.

Oh, before you plug in a new switch, and I said already, you need to make sure that that revision number, it should be set to zero. Because they may just have the same information, or you may not you need to really look at what's going on before you Just putting a device into a national network, okay? two options, you can either go to Transparent mode, and then back to server mode, transparent then back to server. Or you can change the domain name to, I don't know, Disneyland and then change it back to Cisco or allows whatever, that'll also reset the revision number. Make sure that revision number. Okay, now since they are synchronizing with each other, it's going to look at that revision number.

Key key key test question. I guarantee it, okay. Or, or good scenario. All right, look at that revision number. Look at that revision number. You can either ask you how you can change it two ways.

That's all that's all you need to No, you can change in two ways. And look right here. I even put it right there key topic. Higher revision number will take over. Careful. So it asked the question, now you know me I'm doing this.

I'm talking about it to death. And my god since the CCNA. Be careful with those scenarios. Take a good look. If it's a print string, take a good look at what you're what you're seeing in front of you. It's okay.

Domain last domain last. Okay, revision number one, version four. Oh, so I'm going to take this guy and pass it on. But the way they trick you is they say this is server This is client. But what does it say here when the synchronizer What does it look at? There's nothing with a revision number.

They're looking at that revision number by the same domain. A client will send also information will forward information. But now you have a higher revision number. Sure, you said And there's two different ways of doing all right. Well, you know, Susan
