<div class="moz-cite-prefix">Dear José,<br>
<br>
The expiration time is defined by TTL. This is a hard coded
parameter that is defined by DEFAULT_DATA_CACHE_TTL (defs.h) and
is used in mapping_record_init_hdr(lisp_message_fields.c) . We
usually set this value to 10 (10 minutes). I don't know why you
have 1, may be I sent to you a testing version. In a future we
would like to add this parameter in the configuration file but we
don't have it yet.<br>
<br>
Best regards<br>
<br>
Albert<br>

</div>
<div>I am not sure if I am doing something wrong.. (probably
:)) </div>
<div><br>
</div>
<div>Is there any way to handle this transparently? For
instance, have xTR refreshing prefixes 5secs before
expiration, so, traffic is not interrupted?<br>
</div>
<div>Are these expiration timers, configurable? I only see
that rloc-probing timers are tunable.</div>
