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

<interface> Specifies the interface (in th e format type slot/port) that contains the IP address

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

Default Values

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

Applicable Platforms

This command applies to the NetVanta 300, 1000R, 2000, 3000, 4000, and 5000 and Total Access 900

Series units.

Command History

Release 1.1 Command was introduced.

Release 11.1 Command was expanded to include demand interfaces.

Functional Notes

If 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 mod e confi gur es the PPP inter face to use the IP a ddr ess assigned to th e Ethe rnet

interface for all IP processing. In addition, the AOS 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
