Cisco have a feature called BGP-SD (BGP Selective Download).

With BGP-SD, you can hold millions of entries in RAM, but decide what
gets downloaded into the FIB. By doing this, you can still export a full
BGP table to customers directly connected to your 6500, and only have a
0/0 + ::/0 (and some more customer routes) in the FIB to do forwarding
to a bigger box.

BGP-SD started shipping in IOS XE, but I now understand that the feature
is on anything running IOS 15.

This would be my recommendation.
