11.7.2 Correspondent Binding Procedure

   When the mobile node is assured that its home address is valid, it
   can initiate a correspondent binding procedure with the purpose of
   allowing the correspondent node to cache the mobile node's current
   care-of address.  This procedure consists of the return routability
   procedure followed by a binding procedure.

   This section defines when to initiate the correspondent binding
   procedure, and rules to follow when performing it.

   After the mobile node has sent a Binding Update to its home agent to
   register a new primary care-of address (as described in Section
   11.7.1), the mobile node SHOULD initiate a correspondent binding
   procedure for each node that already appears in the mobile node's
   Binding Update List.  This is necessary in order to ensure that
   correspondent nodes do not have invalid information about the current
   location of the mobile node.  The initiated procedures can be used to
   either update or delete binding information in the correspondent
   node.
