Configuration prerequisites

Assign an IP address to the interface from which you want to borrow the IP address. Alternatively,
you can configure the interface to obtain one through BOOTP, DHCP, or PPP address negotiation.

Configuration procedure

To configure IP unnumbered on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Specify the interface to borrow
the IP address of the specified
interface.
A dynamic routing protocol cannot be enabled on the interface where IP unnumbered is configured.
To enable the interface to communicate with other devices, configure a static route to the peer device
on the interface. For more configuration information, see

Displaying and maintaining IP addressing

Execute display commands in any view.

Task

Display IP configuration and statistics for the
specified or all Layer 3 interfaces.
Display brief IP configuration for Layer 3 interfaces.

Network requirements
As shown in
segments: 172.16.1.0/24 and 172.16.2.0/24.
To enable the hosts on the two network segments to communicate with the external network through
the router, and to enable the hosts on the LAN to communicate with each other:
•
Assign a primary IP address and a secondary IP address to GigabitEthernet 2/0/1 on the router.
•
Set the primary IP address of the router as the gateway address of the PCs on subnet
172.16.1.0/24. Set the secondary IP address of the router as the gateway address of the PCs
on subnet 172.16.2.0/24.
Figure 13, GigabitEthernet 2/0/1 on the router is connected to a LAN comprising two
