Release Information

Statement introduced before JUNOS Release 7.4.

Support for aggregated Ethernet added in JUNOS Release 9.4.

Description

For J-series Services Routers and M120 Internet routers with PPP over Ethernet interfaces, configure the interface on which PPP over Ethernet is running.

For demux interfaces, configure the underlying interface on which the demultiplexing (demux) interface is running.

Options

interface-name—Name of the interface on which PPP over Ethernet or demux is running. For example, at-0/0/1.0 (ATM VC), fe-1/0/1.0 (Fast Ethernet interface), ge-2/0/0.0 (Gigabit Ethernet interface), or ae1.0 (aggregated Ethernet interface).

Usage Guidelines

See Configuring an IP Demux Underlying Interface, Specifying the Demux Underlying Interface, and Configuring PPPoE.
