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, 3000, and 4000 Series units.
Command History
Release 1.1 Command was introduced.
Release 8.1 ATM sub-interface was added.
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 Frame
Relay Sub-Interface Configuration mode configures the Frame Relay sub-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.
Usage Examples
The following example configures the ATM sub-interface 1.1 to use the IP address assigned to the
Ethernet interface (eth 0/1):
(config)#interface atm 1.1
(config-atm 1.1)#ip unnumbered eth 0/1
