SROS Command Line Interface Reference Guide ATM Sub-Interface Config 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 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: ATM sub-interface, Ethernet, virtual Frame Relay

sub-interfaces, virtual PPP, loopback interfaces, and VLAN 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: ATM sub-interface, Ethernet, virtual Frame Relay

sub-interfaces, and virtual PPP 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 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 Secure Router OS 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
