Release Information

Statement introduced in JUNOS Release 9.0.

Description

For unnumbered Ethernet interfaces configured with a loopback interface as the donor interface, specify one of the loopback interface’s secondary addresses as the preferred source address for the unnumbered Ethernet interface. Configuring the preferred source address enables you to use an IP address other than the primary IP address on some of the unnumbered Ethernet interfaces in your network.

Currently, configuration of a preferred source address for unnumbered Ethernet interfaces is supported only for the IPv4 address family.

Options

address—Secondary IP address of the donor loopback interface.

Usage Guidelines

See Configuring an Unnumbered Interface.
