That's how we have our XMR currently configured:
show default values | include System|ip.*route
System Parameters Default Maximum Current Actual Bootup
Revertible
ip-route 204800 1048576 786432 786432 786432
Yes
ipv6-route 65536 245760 65536 65536 65536
Yes
ip-vrf-route 5120 262144 5120 5120 5120
Yes
ipv6-vrf-route 128 16384 128 128 128
Yes
show run | include cam|system-max
system-max ip-cache 786432
system-max ip-route 786432
system-max virtual-interface 4095
cam-partition profile multi-service-4
I do not know what headroom, if any, we have left to increase those
values individually.

Out of interest, what will my XMR hold for both? I've been told 1 million IPv4.
so if I wanted to split this into IPv4 and IPv6 does that give me 750K IPv4 and
62.5K IPv6?
Thanks

Subject: Re: [f-nsp] CER FIB capacity
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.

Subject: [f-nsp] CER FIB capacity
Hi
I know that CER (non-RT version) have FIB for 512K IPv4 / 128K IPv6.
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.
