Configuring unnumbered IP interfaces

Unnumbered IP is a feature that enables you to configure a point-to-point interface to borrow an
IP address from another interface. Unnumbered IP enables IP processing on a point-to-point
interface without assigning an explicit IP address to the interface.
Although unnumbered IP is supported on all point-to-point interfaces, the main use of the
feature is to enable dynamic routing on the Dialer interface. The Dialer interface is used for the
modem dial-backup feature. Refer to
feature that sets up a backup dialing destination for a branch gateway. Modem dial-backup
requires unnumbered IP to be configured on the Dialer interface of the branch gateway and at
both the default and the backup dialing destinations.
