6.8 ICMP Mobile Prefix Advertisement Message Format
                    
(snip)
                    
   The Mobile Prefix Advertisement messages may have options.  These
   options MUST use the option format defined in RFC 2461 [12].  This
   document defines one option which may be carried in a Mobile Prefix
   Advertisement message, but future documents may define new options.
   Mobile nodes MUST silently ignore any options they do not recognize
   and continue processing the message.
                    
   Prefix Information
                    
      Each message contains one or more Prefix Information options.
      Each option carries the prefix(es) that the mobile node should use
      to configure its home address(es).  Section 10.6 describes which
      prefixes should be advertised to the mobile node.
                    
      The Prefix Information option is defined in Section 4.6.2 of RFC
      2461 [12], with modifications defined in Section 7.2 of this
      specification.  The home agent MUST use this modified Prefix
      Information option to send home network prefixes as defined in
      Section 10.6.1.
                    
   If the Advertisement is sent in response to a Mobile Prefix
   Solicitation, the home agent MUST copy the Identifier value from that
   message into the Identifier field of the Advertisement.
