<div class="moz-cite-prefix">Hi,<br>
<br>
This is something really strange. When an RLOC of an xTR is
modified, OOR should start the SMR procedure. The SMR should
notify all the xTRs that were talking with our xTR (entries of
the map cache) that have had a change with our EID. It doesn't
appear anything related to SMR in the logs when you modify the
RLOC?<br>
<br>
Best regards<br>

<div>I forgot to mention I changed that timer some time ago, to
deal with the fact that when one xTR changed its RLOC, it took
up to 10m to get the other xTRs to notice it. But did not
realize this side effect.</div>
<div>I reverted to 10m, and I see the same behavior (though with
larger interval)<br>

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>

</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>
