   Source Address
      An IPv6 address assigned to the interface from which this message
      is sent.

   Destination Address
      The IPv6 all-node multicast address.  This address is specified in
      its link-scope format, which is FF02::1.

   Hop Limit      255

   Authentication Header
      If a Security Association for the IP Authentication Header exists
      between the sender and the destination, then the sender SHOULD
      include this header.

   ICMP Fields:

      Type           141

      Code           0

      Checksum       The ICMP checksum.  See [ICMPv6].

      Reserved       This field is unused.  It MUST be initialized to

                     receiver.

   Required options:

   The sender node MUST send the following options in the Solicitation
   message:

      Source Link-Layer Address
         The link-layer address of the sender.

      Target Link-Layer Address
         The link-layer address of the target node.

   Other valid options:

   The sender node MAY choose to add the following options in the
   Solicitation message:

   Source Address List
      The list of one or more IPv6 addresses of the interface identified
      by the Source Link-Layer Address.  This option is defined in
      section 3.
