Accounting Data to Multiple Servers

Hi, I'd like to send RADIUS accounting data to three separate accounting servers. I believe most of the configuration I need can be borrowed from robust-proxy-accounting from the default sites-available. However, I don't think "type = load-balancing" in the pool declaration is the option I need. Could someone point me in the right direction to make sure all three servers get all accounting data? Thanks, Russ Woodman russ@natcotech.com
