Intervlan connectivity / routing / configuration via router on a stick

A subscriber had a question about how vlans can communicate with each other, remember the difference between a logical connection and a physical connection. If you have one switch, but there is more than 1 network even though the devices are physically connected they are logically separate. In the example of this video we have 2 vlans yellow and blue. In vlan yellow we have one computer and in vlan blue we have two computers, each in their own respective network. Therefore, blue can talk to blue and yellow can talk to yellow, but it is not until we add a layer 3 device such as a router that blue would be able to talk to yellow and vice versa. There is 3 different ways, this could be achieved. One cable for every vlan to the router (not best practice) Layer 3 switch ( layer 3 device) Router on a stick (which we demo on this video) #ccna #vlan #ciscopackettracer #networking
