I'm interested:
If RoS is fully functional on CRS125-24G.
Especially if it normally supports MPLS and BGP?
And what is MTU on ports?
sure no huge configurations for such low-perf deviceYes, it does. But if you will use purely as a router, remember that it's performance is not so high (it is a MIPS CPU). You could assign some ports to be a router, and the rest for switching. Yes, it will support BGP and MPLS, just like any RouterOS device.
Sorry if I seem harsh, but where the hell do you get your infos from?!Unfortunately, layer 3 routing ASICs are still.....super inflated in cost as one can make a LOOOOOOT of money off of them. That and they're pretty difficult to make.
Coo coo coo, thank you much Normis. A 25% could always help out for CPU starved situations.L2MTU is 4064
CPU clock variants are min 500/ default 600/ max 750MHz
I get my info from checking on which devices are layer 3 capable in ASICs vs which devices are layer 3 capable through a general purpose CPU. Look at the price differences between the two and you'll see that ASICs that route are NOT cheap. I will agree that the ASICs themselves aren't anywhere NEAR as expensive as they used to be, but they are still very expensive compared to a general purpose CPU. Mikrotik isn't forced to design the ASICs as they could go to like Fulcrum, or Broadcom, or Marvell. However it'd take a while for them to actually write ROS to support said silicon assuming the licensing costs don't make it prohibitively expensive.Sorry if I seem harsh, but where the hell do you get your infos from?!
They aren't expensive anymore and also they aren't that difficult to make. We don't live in the 80s..
Also a small company like MikroTik isn't forced to design those ASICs themself.
If you need examples, then maybe look up the BCM56512, licensing costs may be a bit to high for MT but in that case they could use an Cavium Octeon CN5020 and have an SoC with included CPU and packet accelaration in the 2-3Gbps range.
An L3 routing capable switch, with TCAM based forwarding(so pure hardware no CPU) is around 200$ as an end product... This would be perfectly in MTs market segment.I get my info from checking on which devices are layer 3 capable in ASICs vs which devices are layer 3 capable through a general purpose CPU.

First of all, the Tilera SoC doesn't do anything in hardware, especially not MPLS everything has to be done in software, you can use zero-overhead-linux support from Tilera to reduce the software running on each core/tile to pure application code with no OS dependencies. On a side note, this is super expensive in terms of evelopment time. I think MT is truggling with exactly this i.e. for the Tilera to deliver high-performance MT has to rewrite all of their forwarding code, that's why we suddenly see fastpath support i suspect.They could have gone with an Octeon (like Ubiquiti) but I think they wanted more performance. I think that's why they went with Tilera. That and I don't know if the Octeon supports MPLS inspection in hardware. Clearly the Tilera seems to. That being said, I'm sure the Octeon could be coded to but not sure if it would be as speedy as the Tilera. My curiosity is if there's going to be a time when they get like.....multiple Tilera CPUs working in tandem in something like the new CRS switch they got going.
octeon is very quick and I do expect the hardware itself to be capable of mpls forwarding, on the software side it's not there yet.Coo coo coo, thank you much Normis. A 25% could always help out for CPU starved situations.L2MTU is 4064
