Hi,
I have question about hardware routing with Mikrotik devices. Are there any plans to implements some CAM/TCAMs to Mikrotik devices for hardware routing? Or just expand MPLS accelerated hardware like CRS317?

CRS 600MHz are derived from the RB2011.You should not compare CRS with other manufacturer's "L3 routing switches". Those are completely different things.
CRS is just an L2 switch with a Raspberry-Pi built in to do some routing e.g. for a management network only.
It is not possible to route "production traffic" with a CRS at anywhere near the switching speed.
Instead you could get a router device from MikroTik (RB4011, RB1100, CCR1009) or of course a device from another manufacturer (more expensive, but for a reason).
I am not interested in better CRS switching, but better routing.
My point (explained above) is that such things are not a matter of "enabling that functionality", which you could read as "set some bit during init, maybe load some routing table in the chip".The question he is asking is if MIkroTik is considering enabling that functionality (which already exists in the chip) in RouterOS.
I am not asking for wirespeed routing, just that they leverage what they already developed.I am not interested in better CRS switching, but better routing.
Which takes more expensive silicon. MT don't need te develop it themselves, there is merchant silicon like Broadcom Qumran-UX available, which would make a dandy 'CRS426' full L3 switch, but that stuff isn't cheap. At least not compared to the Marvell PresteraDXes they are using now.
10G L2 switching is cheap. Real 10G routing (read 'wirespeed or close on all available ports') is not. Yet.
As you can see in the block diagram posted above, the CPU is not a distinct chip that you can replace with a faster one, it is an integral part of the switching chip used.The CRS could route faster just by having the same CPU as the RB4011 similarly to what has been done before, that is the point.
But new models could route faster if they were a RB4011 with different switch chip.As you can see in the block diagram posted above, the CPU is not a distinct chip that you can replace with a faster one, it is an integral part of the switching chip used.The CRS could route faster just by having the same CPU as the RB4011 similarly to what has been done before, that is the point.
It has limited performance because it was intended to be used mainly for management and monitoring, not for routing.
