Imagine I want to make sure that whatever happens to interface fa0/2 doesn’t influence the SVI state:I can use the switchport autostate exclude command. In this example we’ll use a router for the job. Fa0/1 is the only interface that can now influence the SVI state, as soon as it goes down you’ll see that SVI state go down as well, even though fa0/2 is still up and running.Enough about the SVI, there’s another method we can use our multilayer switch for routing. This means it won’t influence the state of the SVI interface anymore. VLANs divide broadcast domains in a LAN environment. On the Core Switch, for each Layer 2 vlan we will configure an SVI (Switch Virtual Interface) which will serve as the default gateway for all hosts connected to that particular VLAN. Here’s how to configure this:This is how we configure SW1. A routed port is the exact same interface as what we use on a router.
