Configuring an Interface to Be Unnumbered

To configure an interface to be unnumbered, include the unnumbered-address and destination statements in the configuration:




unnumbered-address interface-name destination address;

The unnumbered-address statement enables the local address to be derived from the specified interface. The interface name must include a logical unit number and must have a configured address (see Configuring the Interface Address). Specify the IP address of the remote interface with the destination statement.

You can include these statements at the following hierarchy levels:

[edit interfaces interface-name unit logical-unit-number family inet]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number family inet]

If you include the unnumbered-address statement in the configuration, you cannot include the address or negotiate-address statement in the interface configuration.

When you include the unnumbered-address statement in the interface configuration, you can assign PPP properties to the remote end, as shown in Assigning a Destination Profile to the Remote End.
