SROS Command Line Interface Reference Guide
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>
Default Values
By default, all interfaces are configured to use a specified IP address (using the ip address command).
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 ppp 1 while in the Loopback
Interface Configuration mode configures the Loopback interface to use the IP address assigned to the
PPP interface for all IP processing. In addition, the SROS uses the specified interface information when
sending route updates over the unnumbered interface.
Usage Examples
The following example configures the loopback interface (labeled loop 1) to use the IP address assigned
to the PPP interface (PPP 1):
ProCurve(config)#interface loopback 1
ProCurve(config-loop 1)#ip unnumbered ppp 1
5991-2114
Specifies the interface in the format type slot/port (e.g., ppp 1) that contains the
IP address to be used as the source address for all packets transmitted on this
interface.
