2.4.2 Configuring a Primary IP Address for the Interface from
Which an IP Address Will Be Borrowed
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The view of the interface from which an IP address will be borrowed is displayed.
The interface can be an Ethernet interface, a loopback interface, an Eth-Trunk interface, or a
VLANIF interface.
Step 3 Run:
ip address ip-address { mask | mask-length }
A primary IP address is configured for the interface from which an IP address will be borrowed.
An interface has only one primary IP address. If you configure a new primary address on an
interface that already has a primary IP address, the new IP address overrides the original one.

NOTE
Only the configurations related to IP address unnumbered are described here. The procedure for configuring
a static route to the peer device is not mentioned here.
The IP unnumbered interface cannot be enabled with dynamic routing protocols because it does not have
an IP address itself. To implement communication between the AR150/200 and the peer device, configure
a static route to the peer device.
