Description
This command sets an IP interface as an unnumbered interface and specifies the IP address to be used

An error message will be generated if an unnumbered interface is configured, and an IP address
already exists on this interface.
The no form of the command removes the IP address from the interface, effectively removing the
unnumbered property. The interface must be shutdown before no unnumbered is issued to delete
the IP address from the interface, or an error message will be generated.

unnumbered IP interface in dotted decimal notation. The configured IP address must exist on this
node. It is recommended to use the system IP address as it is not associated with a particular
interface and is therefore always reachable. The system IP address is the default if no ip-addr or
ip-int-name is configured.
