5.5.  Creation of Global and Site-Local Addresses


   Global and site-local addresses are formed by appending an interface
   identifier to a prefix of appropriate length. Prefixes are obtained
   from Prefix Information options contained in Router Advertisements.
   Creation of global and site-local addresses and configuration of
   other parameters as described in this section SHOULD be locally
   configurable. However, the processing described below MUST be enabled
   by default.


   (omit)


5.5.3.  Router Advertisement Processing


   (omit)


   For each Prefix-Information option in the Router Advertisement:


    a) If the Autonomous flag is not set, silently ignore the
       Prefix Information
       option.


    b) If the prefix is the link-local prefix, silently ignore the
       Prefix Information option.


    c) If the preferred lifetime is greater than the valid lifetime,
       silently ignore the Prefix Information option. A node MAY wish to
       log a system management error in this case.


    d) If the prefix advertised does not match the prefix of an address
       already in the list, and the Valid Lifetime is not 0, form an
       address (and add it to the list) by combining the advertised
       prefix with the link's interface identifier as follows:


   |            128 - N bits               |       N bits           |
   +---------------------------------------+------------------------+
   |            link prefix                |  interface identifier  |
   +----------------------------------------------------------------+




       If the sum of the prefix length and interface identifier length
       does not equal 128 bits, the Prefix Information option MUST be
       ignored.  An implementation MAY wish to log a system management
       error in this case. It is the responsibility of the system
       administrator to insure that the lengths of prefixes contained in
       Router Advertisements are consistent with the length of interface
       identifiers for that link type. Note that interface identifiers
       will typically be 64-bits long and based on EUI-64 identifiers as
       described in [ADDR-ARCH].


       If an address is formed successfully, the host adds it to the
       list of addresses assigned to the interface, initializing its
       preferred and valid lifetime values from the Prefix Information
       option.


   (omit)


5.5.4.  Address Lifetime Expiry


   A preferred address becomes deprecated when its preferred lifetime
   expires.  A deprecated address SHOULD continue to be used as a source
   address in existing communications, but SHOULD NOT be used in new
   communications if an alternate (non-deprecated) address is available
   and has sufficient scope.  IP and higher layers (e.g., TCP, UDP) MUST
   continue to accept datagrams destined to a deprecated address since a
   deprecated address is still a valid address for the interface. An
   implementation MAY prevent any new communication from using a
   deprecated address, but system management MUST have the ability to
   disable such a facility, and the facility MUST be disabled by
   default.


   An address (and its association with an interface) becomes invalid
   when its valid lifetime expires.  An invalid address MUST NOT be used
   as a source address in outgoing communications and MUST NOT be
   recognized as a destination on a receiving interface.


RFC2461




   (omit)


7.2.4.  Sending Solicited Neighbor Advertisements


   A node sends a Neighbor Advertisement in response to a valid Neighbor
   Solicitation targeting one of the node's assigned addresses.  The
   Target Address of the advertisement is copied from the Target Address
   of the solicitation.  If the solicitation's IP Destination Address is
   not a multicast address, the Target Link-Layer Address option MAY be
   omitted; the neighboring node's cached value must already be current
   in order for the solicitation to have been received.  If the
   solicitation's IP Destination Address is a multicast address, the
   Target Link-Layer option MUST be included in the advertisement.
   Furthermore, if the node is a router, it MUST set the Router flag to
   one; otherwise it MUST set the flag to zero.


   If the Target Address is either an anycast address or a unicast
   address for which the node is providing proxy service, or the Target
   Link-Layer Address option is not included, the Override flag SHOULD
   be set to zero.  Otherwise, the Override flag SHOULD be set to one.
   Proper setting of the Override flag ensures that nodes give
   preference to non-proxy advertisements, even when received after
   proxy advertisements, and also ensures that the first advertisement
   for an anycast address "wins".


   If the source of the solicitation is the unspecified address, the
   node MUST set the Solicited flag to zero and multicast the
   advertisement to the all-nodes address.  Otherwise, the node MUST set
   the Solicited flag to one and unicast the advertisement to the Source
   Address of the solicitation.


   If the Target Address is an anycast address the sender SHOULD delay
   sending a response for a random time between 0 and
   MAX_ANYCAST_DELAY_TIME seconds.
   Because unicast Neighbor Solicitations are not required to include a
   Source Link-Layer Address, it is possible that a node sending a
   solicited Neighbor Advertisement does not have a corresponding link-
   layer address for its neighbor in its Neighbor Cache.  In such
   situations, a node will first have to use Neighbor Discovery to
   determine the link-layer address of its neighbor (i.e, send out a
   multicast Neighbor Solicitation).
