Example: Configuring a Demux Interface

Configure two VLANs, each with two IP demux interfaces. One VLAN demultiplexes based on the source address; the other VLAN demultiplexes based on the destination address.

Note: This example is not intended to depict any realistic deployment; it is intended to demonstrate many possible CLI variations.
