Yes, there are some little knobs to tune the CAM but they haven't convinced me 
until now. Especially this two statements from the orgininal Foundry doc's 
makes me wonder:

 "If most of the BGP4 routes actually go to the same set of next hops as the 
default route, enable the CAM network aggregation feature."

 "CAM network aggregation requires a default route in the IP route table."

I must have a default route on my BGP router towards my peer(s)/next-hop(s)? 
Unfortunately my default is null0 on all my border routers.
Maybe someone can enlighten me in the case I have misread the doc's but if 
this is true the net-agg feature is pretty useless for me (and many others i 
think).

Yes of course and that's what I try to say - it's a matter of CAM size (and 
CAM trashing like Kristian mentioned in his post).
