Demultiplexing Interface Overview

Demultiplexing (demux) interfaces are logical interfaces that share a common, underlying interface. You can configure either IP demultiplexing interfaces or VLAN demultiplexing interfaces. IP demux interfaces use the IP source or destination address to demultiplex received packets when the subscriber is not uniquely identified by a Layer 2 circuit. VLAN demux interfaces use the VLAN ID to demultiplex received packets when the subscriber is not uniquely identified. Demux interfaces are supported on M120 or MX Series routers only.

Note: You can also configure demux interfaces dynamically. For information about how to configure dynamic IP demux or dynamic VLAN demux interfaces, see the Subscriber Access Configuration Guide.
