11.7.4 Receiving Binding Refresh Requests

   When a mobile node receives a packet containing a Binding Refresh
   Request message and there already exists a Binding Update List entry
   for the source of the Binding Refresh Request, it SHOULD start a
   return routability procedure.  The mobile node MAY also choose to
   ignore the Binding Refresh Request.  Also, the mobile node can at any
   time delete its binding from a correspondent node.
