Alright, welcome back everyone. Here we are in our full layer two, lab right or layer two switching lab. All these are layer two switches. And we're going to go ahead and create something we've done before in the CCNA course, but now we do it in the CCNP is the only difference in layer three, that will be you actually be doing the layer three routing, and the VLANs and are the end there and just slightly different commands, but the concept is the same. Why so what we're going to do though, ah, and you'll see We'll talk about it later on during the course. We're going to create our VLANs in the core switch.

So what I'm going to do is I'm going to put this over here. Alright, and when does this way, open this up so you can see clearly Okay, So we're gonna enable config T, and we're gonna do host name. And we'll call it core. Right? We're create the VLANs was created VLANs VLAN 100. Name, HR VLAN 200.

Name, ACC t. Now when you're doing your own labs, you don't have to name them or number them what I numbering them into your own if you want, follow exactly what I'm doing and that's fine. Doesn't matter. The number doesn't Well, if you go above terrorism or if you're getting usual. If you go above 105, then that becomes a different story, then that becomes a different story. Okay, but we're not going to do that. We're not going to do that.

So we've created two VLANs. As you can see right here, we've created VLAN 100. And we created VLAN 200. But now I'm not assigning these VLANs to these particular ports up here, these are just going to have them there. Because what's going to happen is when I trunk these ports, they're going to propagate, okay, we're going to create a domain, which we'll talk about later, right? And within the VTP, using the BGP protocol.

So let's go ahead and do that. So we're here. Let's exit once, and let's create a VTP domain, and we'll call last. Okay, and then we're going to trunk the appropriate ports. Now you see these ports up here, 22, and 23. Now we eventually want to extend our VLANs right, from just layer two to layer three and layer three device which we don't have.

So we're going to add a router later on so you can see what's going on. take it a step at a time. This lab will grow. okay to be domain class and astronomy reports in and we're gonna use a range command. So doing one by one, zero, slash two, two through two, three. And we'll do switch port mode trunk.

Okay, so what do we do? all we did is social VLAN is we did create the VLANs, which you've already seen, right? And there they are 100 and accounting, but they're not part of any forts whatsoever. They don't belong to any ports, I'm not going to assign them to any ports. Now, if you do a command called show VTP status, or not sure for status, you're going to see that we have a domain name here. I didn't put a password.

There's not a lot for that. But I did put a VTP domain names or my switches will be in the VTP domain. And by default, you see word server mode, so remote and again, this will explain a little bit more later on. Okay, so that's it. That's all we're going to do here. So we're going to minimize this right here.

And we're going to go to another beam, we're going to go to this switch right here, switch one sobered up, so you can see it nice and neat. Why the first thing we'll do is we'll name it, let's name this HR. So this is host name, HR. And we're going to change the mode of this particular switch to VTP mode client. And again, we'll discuss this later on the TP mode client. But if you're taking the CCNA you know what I'm doing.

Alright, so now I'm going to show you what happened. Do show VLAN. You see that that VLAN or those VLANs are created came down came down but also do show VTP stat. I am part of the last domain as well. And the reason that this happens because these ports are dynamically auto, and we trunk the ports, Port 22 and 23 do show and trunk merely something you can do on their show and trunk. Or you see that that auto, that's the most important and it automatically got trumped.

Okay using the it'll to wonky protocol. So, what we wanted to happen happened, which we got 102 hundred now 100 is faculty. All right, or HR should say. So we're going to go ahead and assign the 100 VLAN to sort imports here, how do we do that? We go to interface range F Zero slash one through 15. switch port mode access now to be access ports, switch port access VLAN 100 now you see that the lights turn Amber, they're going from auto to access and I'm putting assigning that VLAN there. So that's it.

That's all I'm doing there. Now that PC is part of being on 100 Okay, so we're going to go on to the other switch. Okay, and we set a counter Well, let's see. Yeah, let's go to hostname config t host name ACGT And then VTP mode client and as verify their evidence came down do show VLAN and They sure did here they are right there, your was your 201 hundred and you know already they're gonna be part of the same domain. So let's what an assign those VLANs and range f 00 slash one through 15 and then switch port mode access tab is great. Unfortunately you can't use it in the test.

Now for ccmp you can you can and then switch port access VLAN 200 and then do wr awesome. Right now. That's it. They're part of that particular VLAN if you want it to take a look to see it as far as I mean it will go show VLAN Things are brief, see all this bunch of stuff. And you can see that the accounting is active on those ports right there. Okay, not HR HR will be on the other ports right on the same port, but on the other switch.

Now, the thing is that these computers cannot communicate with each other. They're in two separate VLANs, two separate broadcast domains. The PCs IP address is 100 dot 1192168. And one I chose to say 200 dot one, so they can get to each other if I were to ping. And let's do an IP config. So you can see IP config.

Plans to the wall. There's an IP address others here's 100 dot one. Why am I gateway and my default gateway, do I have a default gateway right now? No, I do not. But let's try to ping anyone. So let's not let's pane, the switch on the other side, pane 192168 dot 200 dot one and is not going to be successful is going to give you either an unreachable or request.

Now, in this case is giving you a request timeout. Why? Because it just didn't know how to get back. That's what it is. It can't reach it really, but it doesn't know how to get back. Well, it's lost, the packet is lost.

So what do you need, like we said in the presentation, you need a layer three device. So let's go ahead and just grab an 1841 router. We'll make this very simple. All right, and we're going to go ahead and connect the switch for 24 to Port 00 minus one it talks about that you need to create sub interfaces and the encapsulation needs to match the switch. Okay, we'll bring it over to one side says when you're working on the router, we're done working on With the switches, or arlie huh? Did you think about that?

Ctrl C? Did you ever make that mistake when you press yes and anything at all Ctrl C will get you out in unsettled mode. All right, enable config T will name this router one hostname, or one. And we'll go directly into the interface interface F Zero slash zero. Now we have two networks. But we're not going to use the two different interfaces, we could if we wanted to, but that wouldn't really make sense.

Alright, so we're just gonna say no shot on the physical interface. And now I'm going to up arrow and do Okay, let's do the first VLAN of 00 slash zero dot 100. That's the sub interface that I'm creating. Then you must create the encapsulation in cap dot one Q, one Q, and this number that I'm about to put here must match the VLAN ID, the sub interface number doesn't matter what it is, but the dot one two must match, I put the same number just for visualization purposes. And then you put your IP address which is your default gateway 192168 100 254 255-255-2550. And then let's go ahead and do the second one.

I'm just gonna pop out the the commands, but 200 do the encapsulation 200. And then the IP address is going to be 200. Just to make life easy, right Ctrl Z, W, our comments are there. And then we do a show IP in brief. And we see the Hey, so pop. Alright, so let's see if now we can have connectivity across RBI network.

Let's go back to the level 100 PC there. And we saw we got a request timeout. Let's ping again. See what happens. Now we're saying, well, this is Ethernet. Okay, the first request timeout, but it's still not working.

How is that possible? Why is that? Can I even reach my gateway? Okay, one more question. I will let it go. And once you've done that, no doesn't look like it's reaching.

And why is that? Because because we never Trump this port, right? We just trunk these two ports. This port must be trunk as well. That's the purpose of trunk ports, that multiple VLANs in your process, and your sub interface using encapsulation, and right now to do show interface of zero slash 24 There is no new encapsulation it shows a regular ARP ARP a loopback nonsense because it's you didn't put the encapsulation. You didn't trunk it.

So config t interface F Zero slash 24. switch port mode. trunk. Right. We are the fast forward in time. All right. Now let's go back here Ctrl Z.

Let's do a show in trunk and get done at the beginning to look at it now that port is trumped. Now you can see that as trumped now it will do the same thing. You saw we got request timeouts again when we did it one more time, but now we get a reply. Because now you have the trunk port that's facing the layer three device with the same type of encapsulation that's going to permit those multiple VLANs go across And that's all it is in creating a VLAN trunking port, assigning a VLAN why and making sure you have the right type of any capsulation. Now layer three switches, it all is a slightly different command because they allow you to do they'll say on four switch port mode then they want to ISIL or switch on capsulation ISIL or it was going to I was old news, we will want that we want that one too just for the fact of the Ethernet frame that I want to make extends it so we will have those Ethernet frame errors because of big giant frames, all right, because it does increase the frame by four bytes.

All right, and there it is simple. You've done it. Not a big deal. If you have to do this again. Alright, see you in the next one.
