[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number family inet]

Release Information

Statement introduced in JUNOS Release 8.2.

preferred-source-address option introduced in JUNOS Release 9.0.

IP demultiplexing interfaces supported in JUNOS Release 9.2.

Description

For IP demultiplexing interfaces, enable the local address to be derived from the specified interface. Configuring an unnumbered interface enables IP processing on the interface without assigning an explicit IP address to the interface.

Options

interface-name—Name of the interface from which the local address is derived. The specified interface must have a logical unit number and a configured IP address, and must not be an unnumbered interface.
The preferred-source-address statement is explained separately.

Usage Guidelines

See Configuring an Unnumbered Interface.

Required Privilege Level

interface—To view this statement in the configuration.
