[AusNOG] RouterBoard

Mon Mar 10 14:56:55 EST 2014

Zebra/Quagga has been around for a very long time and is a very stable set of daemon's and the backend to Vyatta so any possible issue you would have I am sure finding an answer online would be extremely easy.  I think I have had one bug with it in the last 10 years and that was when 4 byte ASN's came mainstream and that is long fixed.

PFSense is more a Firewall than a router, it does not have a CLI either from my experience.  I love it as an edge firewall ,t is extremely efficient and reliable but short of a Gateway I would not use it for routing at the DC.

Tempting, time ?

Had a look at zebra and a very very quick look at bird.

The other issue is support.

A few people have suggested pfsense, it looks interesting, I think I looked at this a while back, but can't remember why I didn't proceed further.

If you're finding you can do everything in Linux why not just throw Zebra or Bird into the mix and solve your issues that way?

My opinion and we have been using CCR's since the first one arrived in Australia is they are reasonable kit.   Overall I find the performance and price excellent. But there have been just to many unexplained problems for my liking. Not that we dont still use them on the edge we do. Im about to roll one out to quite a far destination over the next week. But the site has a backup and it is non essential.  They are not ready for the core and they are not ready for a network that needs 4 9's   Perhaps we are at 99.9 now.  Then again if I had to run on a tight budget and I had the opportunity to trade off reliability. It would be the number one on my list.

Speed
Reliability
Price

Pick any 3 CCR's fit in to the Speed and Price corner of the triangle.

Hi

Yeah I have read a bit about the single core issues on the CCR, the last time I looked because of this I saw 3 cpu's floating around 30-60% non-maxed

I started this by looking at VM routers, but I couldn't get pas the 1Gb/s nic. There is Brocades vyatta, but its just way to expensive compared to routeros

My constraints are more along the lines of, I have core switching already, I wanted to add some core routing.
I am happy with the CCR on $$ on CLI
I am not so happy about the current performance, be that limited to my testing via iperf...  I am nearly ready to live with that, on the presumption I can get 8+Gbs with multi stream tcp.

My current risk is support, especially as I have had a hard time working through this CCR performance issue.  I don't want to roll out 2 of these at each DC and then run into a bug, where the only solution is to throw it away.  I can duplicate about all the functionality of routeros on linux apart from BGP and OSPF. And I am guessing if I looked really hard and spent some time I could get that working as well.

So taking into account their low $$ I can also live with minimal support if I have another hardware solution to match up with it on a similar $$ level.  If they can talk iBGP, OSPF and VRRP, then I am just about set.  :)

So I thought I would dig into the knowledge pool that is AUSNOG and find out what other devices like RouterOS are being used..

David is correct, the Tilera CPU with RouterOS does struggle with single threaded processes - worse than just BGP operating on a single core, all routing (OSPF, RIP and static) processing will happen on the same core. ROS7 is likely to change this (rumours).
But still, the CCR range has forced a lot of people to change how they think about routing (at a relatively small scale) - and has certainly bought the cost down. "Routed" packets per dollar, I don't think anything in the new hardware market can compete.
Vyatta has other challenges like x86 PCI architecture that will limit your total throughput - however things like processing BGP are drastically improved compared to ROS. Ubiquity has ported the Vyatta/VyOS to MIPS processors, possibly worth a look but I don't think it has any SFP+.
Given Alex's application - storage - a layer 3 solution is not likely to be the best.
Alex, have you considered something like the Brocade VDX Ethernet fabric (VDX could enable 40g native interfaces)? Or at least other layer 2 solutions? I noticed that you have tried routing on switches (Dell) perhaps something with some more power with this design would yield better results for you?

I believe he has the CCR1036-8G-2S+ which has 2x10GB SFP+ ports.

I think the issue he is hitting is the single threaded nature of routerOS for a lot of its functionality.
BGP, for instance spins on a single core. Until ROS becomes multi-core aware/capable a lot of its functionality will be capped at the per core performance.

CCR1036 has no 10G ports, only 1G, so im not sure why you would expect to get a single TCP stream past 1G (even with LACP since that is not how LACP works)

Hi

So I have tested routerOS ... in VM and also bought the ccr1036.

I'm not 100% happy with the ccr1036.  Basically can't push 1 tcp stream past 1Gb/s I can get 8-9Gb/s with multiple streams. I can get UDP up to 9.8Gb/s

I like routerOS interface (have to admit I like the vyatta better from what I saw).

But now I need to find something similar to these devices around the same price and around the same performance, I would like to push it all to a VM but Brocade want my 1st and 2nd child ...

So routerOS support is nowhere close to Cisco and rightly so for the price, so I have some hesitancy in rolling these things out, especially if they are going into the core.

So are there any suggestions from the list ?
