11.5.2 Forming New Care-of Addresses
<PRE>
</PRE>
   After detecting that it has moved from one link to another (i.e., its
   current default router has become unreachable and it has discovered a
   new default router), a mobile node SHOULD generate a new primary
   care-of address using normal IPv6 mechanisms.  A mobile node MAY form
   a new primary care-of address at any time, but a mobile node MUST NOT
   send a Binding Update about a new care-of address to its home agent
   more than MAX_UPDATE_RATE times within a second.
