[AusNOG] Looks like a total beast but would you dare run your core network on it?

Hi

Got 6 of the CCR1036-8G-2Splus
Same points as below
Limit to 1Gb/s tcp stream, but with multistreams or udp I have pushed up to 9.8Gbs
BFD issue

I like them, I would like for them to make the RouterOS VM;s vmware aware and use the vmxnet3 nics, then I could be really happy with Mikrotek.

Mikrotik's have been discussed for a while - plenty are using at the edge, some are using at the core. I personally use CCR1036-8G-2Splus at my core, which use the same CPU architecture as the 1072 just less cores, and different interface options.

I haven't had much issue with them, but I also pick and choose my software releases, and don't configure new (or unused) features on production to avoid bugs.

I run 2 with as much active-active and failover redundancy as I can, and the cost of the 2 ($3k~) still far cheaper than a couple of Cisco routers for my networks ~500mbit / 200kpps throughput. (1 router is currently doing most of that work sitting at 10-15% CPU with conntracking + firewall mangle rules + about 10 simple queues)

The biggest problem is multi-threaded use for some of the important processes in them, BGP being the main one, and single TCP stream being the other. They each seem to be limited to a single core at a time so importing full tables and updates/withdraws can take a bit to propagate in the route table. TCP single stream only seems to be able to get to 1gbps, again seems to be a single core restriction.

ROSv7 is meant to fix a lot of this but still in alpha stage, no public betas even heard of yet.

With equivalent gear from Cisco costing 10x or more might it be worth taking a chance?

If not what else similar is this alternative. I don't mind paying a premium for quality but 10x is a bit ridiculous...
