Hi Mario,

in general, Extended, Base and Low memory options allow the same scale numbers, including FIB, MAC address, Bridge-domain, L3 sub-interface, VRF, etc. The difference is that E/B/L line cards have different TCAM, Stats and Frame Memory size, which give different scale number of the QoS queues and L2 sub-interfaces per line card.

Hope that clarified,

Cheers,

Ivan.
