2.4 Configuring IP Address Unnumbered on an Interface
This section describes how to configure IP address unnumbered.
2.4.1 Establishing the Configuration Task
Before configuring IP address unnumbered, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the data required for the
configuration. This will help you complete the configuration task quickly and accurately.
Applicable Environment
In some application environments, an interface needs to be configured to borrow an IP address
from another interface to save IP addresses. If an interface is seldom used, a fixed IP address is
unnecessary. You can configure the interface to borrow an IP address from another interface.
Pre-configuration Tasks
Before configuring IP address unnumbered on an interface, complete the following tasks:
l Setting physical attributes of the IP unnumbered interface and the interface from which an
IP address will be borrowed
l Setting link layer protocols of the IP unnumbered interface and the interface from which
an IP address will be borrowed
Data Preparation
To configure IP address unnumbered on an interface, you need the following data.
