I don't agree. The MLX can handle up to 512K IPV4 Routes in hardware (=the FIB) and the total size of possible BGP4 IPV4-routes in the RIB is 2 millions. This means you can have up to four full views with 512k routes each. The foundry box is much more powerful than the Cisco gear you mentioned and cannot be compared since forwarding is done in hardware on the line cards and not via software like the 7600 does.
