             STATUS       current
             DESCRIPTION
                 "This textual convention is an extension of the
                 Ipv6IfIndex convention.  The latter defines
                 a greater than zero value used to identify an IPv6
                 interface in the managed system.  This extension
                 permits the additional value of zero.  The value
                 zero is object-specific and must therefore be
                 defined as part of the description of any object
                 which uses this syntax.  Examples of the usage of
                 zero might include situations where interface was
                 unknown, or when none or all interfaces need to be
                 referenced."
