Command Reference Guide PPP Interface Configuration Command Set

ip unnumbered <interface>

Use the ip unnumbered command to use the IP address assigned to the specified interface for all IP

processing on the active interface. Use the no form of this command to remove the unnumbered

configuration.

Syntax Description

Specifies the interface (in the format

type slot/port

) that contains the IP address

to use as the source address for all packets transmitted on this interface.

Valid interfaces include: Ethernet (eth 0/1), virtual frame relay sub-interfaces

(fr 1.16), virtual PPP (ppp 1), and loopback interfaces.

Default Values

By default, all interfaces are configured to use a specified IP address (using the ip address command).

Command Modes

(config-interface)# Interface Configuration Mode required

Valid interfaces include: Ethernet (eth 0/1), virtual frame relay sub-interfaces

(fr 1.16), and virtual PPP interfaces (ppp 1).

Command History

Release 1.1 Command was introduced

Functional Notes

ip unnumbered

is enabled on an interface, all IP traffic from the interface will use a source IP address taken

from the specified interface. For example, specifying

ip unnumbered eth 0/1

while in the PPP Interface

Configuration Mode configures the PPP interface to use the IP address assigned to the Ethernet interface for

all IP processing. In addition, the ADTRAN OS uses the specified interface information when sending route

updates over the unnumbered interface. Static routes may either use the interface name (ppp 1) or the far-end

address (if it will be discovered).

Usage Examples

The following example configures the PPP interface (labeled

ppp 1

) to use the IP address assigned to the

Ethernet interface (

eth 0/1

(config)#

interface ppp 1

(config-ppp 1)#

ip unnumbered eth 0/1
