Hi Rob, the CER routers use SRAM for the IPv4/v6 FIB instead of CAM, so for the CES/CER/CER-RT platforms the scalability is dynamic for all IP routes in the FIB (vs the MLX CAM architecture where we have to choose fixed partition sizes which can support a maximum number).
Scalability depends on how the memory is used by IPv4 and IPv6 routes. There is no easy formula to calculate the utilization, so we have tested certain combinations which are officially supported maximums. While a different number of routes might work, it will not be a supported or tested combination. For CER: 256K IPv4 routes + 128K IPv6 448K IPv4 + 64K IPv6 512K IPv4 + 0 IPv6 For CER-RT: 1.5M IPv4 + 512K IPv6 "Internet route mix" is used to indicate that we are using a mix of prefix lengths. No compression is being used.

My question is CAM is split between IPv4 and IPv6 - I mean if I have 128K IPv6 routes in FIB then I cannot have 512K IPv4 routes at same time.
