VLAN overview
If you want the device to be able to send Layer 3 traffic from one protocol VLAN to another, you
must configure a virtual routing interface on each protocol VLAN, then configure routing
parameters on the virtual routing interfaces. For example, to enable a Layer 3 Switch to route IP
traffic from one IP subnet VLAN to another, you must configure a virtual routing interface on each IP
subnet VLAN, then configure the appropriate IP routing parameters on each of the virtual routing
interfaces.

Layer 2 and Layer 3 traffic within a VLAN
is bridged at Layer 2.
Layer 3 traffic between protocol VLANs
is routed using virtual interfaces (VE).
To route to one another, each protocol
VLAN must have a virtual interface.
