ATOMIC AGGREGATE

Hello, I am trying to understand the BGP ATOMIC AGGREGATE attribute from a BGP router which receives aggregate routes. Can somebody tell me what is the action taken by a BGP router when it receives a aggregate route with ATOMIC AGGREGATE. I understand that the ATOMIC AGGREGATE is used when there is loss of information while aggregating the routes. But what does the receiver of the attribute do with the information. what kind of action does it take ? If anyone can put some light on how this BGP attribute gets utilized in the real world i would greatly appreciate. Thanks in advance. Regards, Phanidhar Koganti.
