Hello Roy,
Just a quick question on section 17.1.3 of RFC 3315. It states 3 options
available to the client in order to select and Advertise message:

--- quote

   Upon receipt of one or more valid Advertise messages, the client
   selects one or more Advertise messages based upon the following
   criteria.

   -  Those Advertise messages with the highest server preference value
      are preferred over all other Advertise messages.

   -  Within a group of Advertise messages with the same server
      preference value, a client MAY select those servers whose
      Advertise messages advertise information of interest to the
      client.  For example, the client may choose a server that returned
      an advertisement with configuration options of interest to the
      client.

   -  The client MAY choose a less-preferred server if that server has a
      better set of advertised parameters, such as the available
      addresses advertised in IAs.

--- end quote

Specifically, when does client pick the last option:

   -  The client MAY choose a less-preferred server if that server has a
      better set of advertised parameters, such as the available
      addresses advertised in IAs.

Also, can application influence this choice (with parameter or something)?

Thanks,
