Configuration guidelines

Follow these guidelines when you configure IP unnumbered:
• An interface cannot borrow an IP address from an unnumbered interface.
Multiple interfaces can use the same unnumbered IP address.
•
If an interface has multiple manually configured IP addresses, only the manually configured primary
•
IP address can be borrowed.
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.

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, or DHCP.

Configuration procedure

To configure IP unnumbered on an interface:
Step
1. Enter system view.
2. Enter Tunnel interface view.
3. Specify the interface to borrow the
IP address of the specified
interface.

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 information for the
specified or all Layer 3 interfaces.
Command
system-view
interface tunnel number
ip address unnumbered
interface interface-type
interface-number
Command
display ip interface [ interface-type interface-number ]
display ip interface [ interface-type
[ interface-number ] ] brief

Remarks
N/A
Create a tunnel interface before
you enter the tunnel interface
view. For more information about
tunnel interfaces, see
"Configuring tunneling."
By default, the interface does not
borrow IP addresses from other
interfaces.
