Your juniper will have RIBs for each peer/protocol pair. In my
experience the memory use scales linearly all else being equal. Also,
I'd be hard-pressed to find a scenario outside of a lab where you will
use more than the 768M of ram that the junipers support these days. My
AADS router is using 128M with 55 peers and mbgp running as well as bgp.
