REFERENCE

(draft-ietf-mobileip-ipv6-24.txt)

9.5.2 Requests to Cache a Binding

   In this case, the receiving node SHOULD create a new entry in its
   Binding Cache for this home address, or update its existing Binding
   Cache entry for this home address, if such an entry already exists.
   The lifetime for the Binding Cache entry is initialized from the
   Lifetime field specified in the Binding Update, although this
   lifetime MAY be reduced by the node caching the binding; the lifetime
   for the Binding Cache entry MUST NOT be greater than the Lifetime
   value specified in the Binding Update.  Any Binding Cache entry MUST
   be deleted after the expiration of its lifetime.

6.1.8 Binding Acknowledgement Message

   Lifetime

      The granted lifetime, in time units of 4 seconds, for which this
      node SHOULD retain the entry for this mobile node in its Binding
      Cache.
