All right, we made it through the section. All right, so let's see what we've done. We've learned about inter VLAN routing on layer three switches we did a lot of on and you saw the things that we had to do from the, from the core switches to the access layer switches. In order for the for the PCs to receive an IP address, we did a lab on that you saw that, we've talked about what all the layer three switches using stuff are to create that forwarding information base table, and how there's different types of subs are the ones we did, this is the one that you want, because each inline car will be able to use the full advantage of that 40 information base. All right, because it's going to have gather a lot more information that you can go ahead and forward and forward your packets to now verify we'll look at how we can verify a multi layer switching using show commands.
Make sure it's working Obviously you already, I already told you that we've done the lab with that. Yes. Me personally. If I want to use a layer three device, it's going to be around. It's going to be a router, it's not going to be a layer three switch on us. That's all I have or whatever in the building.
And that's all I want. What have you. layer two is layer two. layer three is layer three. Okay, can you use layer three switches? Yes.
Okay. Does it has, does it have the same capacities or capabilities? Sure, it does. But a switch is a switch and it does its function. When you start implementing more and more and more, you're going to start burdening it with things that it doesn't need to be doing. That's why we have the OSI model that's why we have the Cisco three layer model now the Cisco collapse architecture model right where this the core distribution or corners regional working together, it me if I'm going to do Even if it's a distribution layer that's going to be routers, I'm gonna configure DHCP on the router.
I don't want to or an actual DHCP server, but let's say DHCP. Or do it on the router. Okay. That's just the way that I that's me. Now for your examination. Can you do DHCP?
Or layer three? Yes. You saw done? Can we do SAF on layer three switches you saw done? Enter VLANs, using layer three. Yes, you saw I don't.
So all these things can be done with just switches. But again, depending on how big your enterprise is, where do you want to place these switches? What is it that you want to do on these switches? Because certain things should stay at layer two, they shouldn't go beyond that. And you're starting to go to Layer three that goes, you're going to start routing, use routers. That's what they're meant to do.
All right. Well, with that said, I'll see you in the next
