Automatic inter VLAN using layer switches, layer three switches. Alright, layer three switches now, we have created VLANs, we've done inter VLANs. That's not a problem was once we create VLANs, we need them to communicate. Alright, in order to do that, we have to do inter VLAN communication. Now using a layer three switch, we must configure the following IP routing sharing on IP routing, you need to trunk your ports. Okay, your appropriate ports going down to your access layer switches, create sub interfaces, if needed.

In this case, when we do our lab, we're just going to go into the VLAN. We're going to go into the VLAN interface and put an IP address and turn on and all that the right type of encapsulation right for your trunk ports, and then the IP configurations per VLAN the IP configurations per VLAN Okay, well That needs to happen needs to happen. Alright. So now what we're really doing is reading a switch, virtual interface and SPI port, multi layer switches have routing capabilities. So we were to actually have another network somewhere else. All right, that our course which we'll connect to, and we can send that out that way, yes, we can go ahead and do that we can route using your IP routing is on.

So you can do a routing protocol allows a network address to be assigned to a logical interface. We, we did it we did it in the lab, or we're going to do it in the lab, the VLAN. And as we are configured separately, yes, you do your VLANs you name your VLANs and then you put your IP address within that VLAN that is how you will create your SPI port. All right. The following is an example here it is taught all really, we know this, we know this all right. Here's the now 100 we name it Baja.

Okay, we exit out of that we go into the interface VLAN 100. We go that P address within that network and we turn on that VLAN. That's it. This is how you do inter VLAN connectivity. But again, you will see this in the lab. I'll see you next
