            For example, when the node configures both a unicast and
            anycast address for a prefix, the ipAddressPrefix objects
            for those addresses will point to a single row in this
            table.

            This table primarily provides support for IPv6 prefixes, and
            several of the objects are less meaningful for IPv4.  The
            table continues to allow IPv4 addresses to allow future
            flexibility.  In order to promote a common configuration,
            this document includes suggestions for default values for
            IPv4 prefixes.  Each of these values may be overridden if an
            object is meaningful to the node.

            All prefixes used by this entity should be included in this
            table independent of how the entity learned the prefix.

            requires examination of the relevant ipNetToPhysicalType
            object.

            physical addresses mapping has been dynamically resolved
            using e.g., IPv4 ARP or the IPv6 Neighbor Discovery
            protocol.

            statically configured.  Both of these refer to entries that
            provide mappings for other entities addresses.

            The 'local(5)' type indicates that the mapping is provided

    MAX-ACCESS not-accessible
    STATUS     current
    DESCRIPTION
           "The index value that uniquely identifies the interface by
            which the router can be reached.  The interface identified
            by a particular value of this index is the same interface as
            identified by the same value of the IF-MIB's ifIndex."

ipDefaultRouterLifetime OBJECT-TYPE
    SYNTAX     Unsigned32 (0..65535)
    UNITS      "seconds"
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
           "The remaining length of time, in seconds, that this router
            will continue to be useful as a default router.  A value of
            zero indicates that it is no longer useful as a default
            router.  It is left to the implementer of the MIB as to
            whether a router with a lifetime of zero is removed from the
            list.

            For IPv6, this value should be extracted from the router
            advertisement messages."

                     reserved (-2),

    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
           "An indication of preference given to this router as a
            default router as described in he Default Router
            Preferences document.  Treating the value as a
            2 bit signed integer allows for simple arithmetic
            comparisons.

            For IPv4 routers or IPv6 routers that are not using the
            updated router advertisement format, this object is set to
            medium (0)."
