I've seen some configs showing the use of subinterfaces to perform vlan routing. If I am using a layer 3 switch, is it a safe practice to create a vlan interface and put an IP on it?
I guess I don't understand the difference between the two. On a layer 3, couldn't I take the trunk from another switch and plug it into the layer 3 switch, then put an IP on that interface and issue the "no switchport" command?
What's the difference between creating the vlan subnet on a physical interface as opposed to creating an svi vlan interface?
