Specifies that this definition is to be deleted from the list of defined interfaces. The intf_name must be the name of an interface previously defined by an INTERFACE statement. INTERFACE DELETE deletes all home IP addresses for the interface.
VIRTUAL

  • A VIRTUAL interface name cannot be coded in the BEGINROUTES block.
