I am considering running 8 eBGP sessions with full-route on each (approx. 3'500'000 prefixes expected). As far as I could figure out, the CAM limit depends on the CAM profile. The XMR seems to support 1M IPv4 prefixes in ipv4 profile mode and 512K on MLX. These figures are according to "CAM partition profiles" of the MLX Configuration Manual.

Prefixes from your 8 eBGP sessions will form your RIB. The best routes are then placed into the FIB. That's where you may hit CAM partitioning limits.

I'm not quite sure what the limit on RIB size is but 3.5M will fit just fine memory-wise in an XMR Management Module.
