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 the 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 mode configures the PPP interface to use the IP address assigned to the Ethernet
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
