The CCR2216-1G-12XS-2XQ is their new flagship router. I see it has 16Gb of ram but what’s does its NAT performance look like? How fast can it stand up connections/sessions/translations and how many can it hold?
Thanks.
I guess my question is could this be used as a ISP core router running CGNAT?
join the questions. I want to use model for nat ISP core. Nat 17-20 Gbit/s. Is the processor performance enough?
NAT
ip_conntrack_count - 500k
Traffic . IN 12Gbits, Out 3 gbit/s
PPS: TX bond0.811: 606639 pkts/s RX bond0.811: 996977 pkts/s
i think its a bad idea, why?:
because CG-NAT will be done by Software using CPU on Fast_track mode with many connections tracked beyond what 2216 can do with hardware offload
i think 2216 is suited for a specific role as core or border router running with hardware offload at full wire-speed
for CPU related tasks 2116 is a better choice because it has the same CPU as 2216 and cost a fraction,
i think the 4x 10g interfaces included on 2116 are more than enough to saturate it in CG-NAT role i think maybe 20 to 30gbps will be the ceiling in that role for 2116 / 2216
there is an exception: if you are aware of this and want to opt for 2216 to reduce your space and power usage getting the CPU muscle and 100g/25g switch in a single machine, that can be a good use case
