S7703 ipv4 routes capacity ??

Hi,

I have a project on going where S7703 is used to establish eBGP peer with internet providers to receive the full routing table.

By documentation the S7703 has a capacity of 1M MAC addresses and 150K ipv4 routes. (On cisco ASR routers there is a possibility to change the profile of the cards to lower the MAC capacity and increase the route capacity for example from 500K to 1M)

Is there such option on the S7703?

If not how can you deal with the internet routing table (550K routes) ?

Thanks in advance
