Choosing Slots to Support the Circuitless Interface
By default, all slots support the IP circuitless interface. To specify the slots that
can support the circuitless interface, complete the following tasks:
Configuring an Unnumbered IP Interface
IP allows you to configure an interface on a point-to-point connection without
using an IP address. Such an interface is called an unnumbered interface. The
ability to establish a point-to-point link using an unnumbered IP interface helps
alleviate two of the major problems caused by the continued rapid growth of the
Internet: exhaustion of Class B network addresses and of the 32-bit IP address
space.
You associate each unnumbered interface with the IP address of any numbered
interface on the router, including the circuitless interface. The router can support
multiple unnumbered interfaces. Multiple unnumbered interfaces can be
associated with the same IP address. Because all traffic over an unnumbered
interface uses broadcast addressing at the link layer, neither an adjacent host
specification nor address resolution is required.
