I am not a fan of the CRS switch. I have had multiple units in the field
and have had issues ranging from CPU load to port compatibility with
other devices. There are other layer 2/3 switches that work very well
though they are more expensive. I use CCR1009 units with Netonix
switches at my tower sites now and don't have problems.

If you're thinking about doing this, don't. I know that the CRS125 is
basically the same as the RB2011 under the hood. Except the CRS has a
single 25-port switch with a 1Gb/s link to the CPU. Compared to the
2011 which has the divided switches and different speeds. I hate it.
3011 was an option, but I still needed more than 10 ports, and I
didn't want to throw in a separate switch.
I had a most ports switched and a couple peeled off for routing.
Pushing about 110 x 30Mbps and maybe 15-18k PPS at peak through it for
the last 24 hours. I kept getting random packet loss and OSPF
adjacencies breaking. I'm betting the processor just couldn't handle
it. Also have to wonder if it was some kind of buffer issue between
the switch and CPU.
Replaced with a 1100AHx2. Oh well. Learning experience. The CRS looks
better than a RB493G on paper, but that is not the case.
