Why should I take this module?

Welcome to Inter-VLAN Routing!

Now you know how to segment and organize your network into VLANs. Hosts can communicate with other hosts in the same VLAN, and you no longer have hosts sending out broadcast messages to every other device in your network, eating up needed bandwidth. But what if a host in one VLAN needs to communicate with a host in a different VLAN? If you are a network administrator, you know that people will want to communicate with other people outside of your network. This is where inter-VLAN routing can help you. Inter-VLAN routing uses a Layer 3 device such as a router or a Layer 3 switch. Let’s take your VLAN expertise and combine it with your network layer skills and put them to the test!
