[AusNOG] Inbound BGP traffic balancing

[Tim Raphael]

This is a fair point, if you're paying for two 100Mbit pipes, perhaps turn down the least used. After all, if you believe the BGP protocol is working correctly, you're actually getting the better performance as determined by the protocol.

Tim Raphael
