I know how to use Google dear Mark, but I mean which configuration is
working succesfully in their network.
I am currently using this config:

bba-group pppoe TEST
 virtual-template 1
 sessions per-mac limit 2
 sessions per-vlan limit 5000
 sessions per-vc throttle 15 30 300
 sessions per-mac throttle 15 30 300
 sessions auto cleanup
