<div>Marcin,</div>
<div> </div>
<div>Why don't you read RFC4271, the only method to notify a peer about error condition is to send a Notification and reset the session.</div>
<div>
<pre class="newpage"><span class="h2"><h2>
<a name="section-1">1</a>. Introduction</h2></span>
According to the base BGP specification [<a title=""A Border Gateway Protocol 4 (BGP-4)"" href="http://tools.ietf.org/html/rfc4271" target="_blank">RFC4271</a>], a BGP speaker that
receives an UPDATE message containing a malformed attribute is
required to reset the session over which the offending attribute was
received</pre>
<pre class="newpage"> </pre>
</div>
<div>There is a recent development, namely draft-ietf-idr-optional-transitive to address this issue, however it is still a draft, not a normative document to follow/implement.</div>
<div>You might also want to read draft-ietf-idr-as0-00, there's a reason for it and just for your understanding for a personal draft to become a working group document, there must be ratehr great support for it.</div>
<div> </div>
<div>Why don't you call names vendors which allow to to set AGGREGATOR to 0 in first place :)?</div>
<div> </div>
<div>Regards,</div>
<div>Jeff<br>

<br>
please please please, what kind of an IDOT is working @ /// and decided to code closing session in faulty attributes instead of ignore and log action ?<br>
I just can't understand it, that person probably had never ever worked at living, public BGP network..<br>
<br>
This is continuation of Aggregator problem started in early 6.3 line (LI)...<br>
They resolved my issue, but still left some sanity check with action CLOSE SESSION.<br>
I hope that after today that person will look for a new job...<br>
<br>
Regards,<br>
Marcin<br>
