Usage Guide
Unnumbered interface is an interface that has IP enabled on it but no IP address is
assigned to it. The unnumbered interface should be associated to an interface with
an IP address. The source IP address of the IP packet generated by an
unnumbered interface is the IP address of the associated interface. In addition, the
routing protocol process determines whether to send route update packets to an
unnumbered interface according to the IP address of the associated interface. The
following restrictions apply when an unnumbered interface is used:
 An Ethernet interface cannot be configured as an unnumbered interface.
 A serial interface can be configured as an unnumbered interface when it is
encapsulated with SLIP, HDLC, PPP, LAPB and Frame-relay. However, when
Frame-relay is used for encapsulation, only the point-to-point interface can be
configured as an unnumbered interface. X.25 encapsulation does not allow
configuration as an unnumbered interface.
 You cannot detect whether an unnumbered interface works normally using the
ping command, because no IP address is configured for the unnumbered
interface. However, the status of the unnumbered interface can be monitored
remotely using SNMP.
