Marcin,

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.


1. Introduction


   According to the base BGP specification [RFC4271<http://tools.ietf.org/html/rfc4271>], 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



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.
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.

Why don't you call names vendors which allow to to set AGGREGATOR to 0 in first place :)?

Regards,
Jeff

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 ?
I just can't understand it, that person probably had never ever worked at living, public BGP network..

This is continuation of Aggregator problem started in early 6.3 line (LI)...
They resolved my issue, but still left some sanity check with action CLOSE SESSION.
I hope that after today that person will look for a new job...

Regards,
Marcin
