Mikrotik NBN NNI head end router Queue issue
by Murray Southwell 14 Dec '15

14 Dec '15

Hi Guys, Is anyone using a MikroTik router as an NBN head end unit? And if so have you managed to create a traffic queue scenario which satisfies the NBN 10ms peak burst rate specification http://www.nbnco.com.au/content/dam/nbnco2/documents/sfaa-wba2-product-cata… We need to be able to configure the Peak Burst Size (PBS) down to less than 10ms. Anything in excess of that is dropped by NBN traffic policing. The limitation of the MikroTik OS (and maybe hardware) is that we can only configure PBS down to 1 second (25M/second) The result is that NBN traffic policing drops packets that exceed 0.25M/10ms, significantly impacting TCP throughput and exhibiting the anticipated sawtooth throughput profile as TCP constantly ramps up and drops back due to lost packets. To make it work I think we need to be able to set a peak burst rate such that a 25M NBN service can have a peak burst rate of 0.25M per 10ms or even better would be .125M/5ms (as 10ms is the Max spec of the NBN) If anyone has this working successfully, I would love to hear how you achieved it :) Kind regards Murray Southwell Tasmanet Pty Ltd Manager - Network Services murray(a)tasmanet.com.au 0361652511 0418145979

IP PROBLEM ON CCR1072-1G-8S+
by Matt Perkins 12 Dec '15

12 Dec '15

Hi All, Got a strange one. I have two CCR 1072's back to back with a short is run (1km or so) of single mode with two 10G SFP+ single mode. The SFP's and run has been previously used and again tested with Cisco equipment without fault. I have also used the same type of SFP+ with CCR1072's without fault. But except for this one setup. The problem is after a random period of time (minutes to hours) one of the CCR's stop's responding to IP. You cant Ping the CCR or connect to it locally. Console works and says all is fine but no bidirectional traffic over the interface. The exception to this is that CDP still seems to be working as you can see the broadcasts from the CCR on a dump at the other end of the link. You can also clear the arp cache at the other end and ping and the mac is re-learning indicating that something is still happening. The only fix appears to be a reboot. When the unit starts behaving normally again for a time. If you set the watchdog it happy reboots the CCR fixing the problem also. Tried 6.33.3 and also the latest RC no luck. My next move is to replace the hardware. But it's a very odd hardware fault has anyone else seen anything like this. Matt. -- /* Matt Perkins Direct 1300 137 379 Spectrum Networks Ptd. Ltd.

Mikrotik with IPoE
by Stephen Schwetz 20 Nov '15

20 Nov '15

Hi All, I have a site that has just switched over to the NBN vdsl service. Optus have supplied their router, which I would like to replace with a vdsl bridge. Has anyone got any information on using the mikrotik with IPoE on the NBN, I would especially love to get a config if you have one. Cheers Stephen

MPLS
by Daniel Hoffman 18 Nov '15

18 Nov '15

Anyone using MPLS and CCR or RoS-x86 at any scale in AU I have a backbone that's been extending and upgrading soon to be 10gbe and 5 POPs. just wondering if some CCR1072 and just l2 switching would be viable so cope with the mixed BW links and path management. I also need to use the switches to terminate the fibre based on a number of SFP and distance discussions. The plan to this point is Telco Systems, Juniper or Similar but thought I'd ask even tho I think I know the answer which is "not to do it". Thoughts?

Band 28 LTE Card
by Matt Perkins 17 Nov '15

17 Nov '15

Hi All, Has anyone had any success with any LTE cards that support band 28 (Telstra's 700Mhz band) with Mikrotik equipment. Im toying around with the idea of putting a hotspot on board an aircraft and you really cant beat the range of Telstra's new band and before anyone says anything about mobile phones on board aircraft I understand the laws and responsibility here. Im a licensed pilot. I already have an Iridium hotspot on board but 2400BPS is not very useful for anything other them SMS and the IPAD does an amazing job on band 28 in 90% of the time but im trying to get an extra 8~9 % Matt. -- /* Matt Perkins Direct 1300 137 379 Spectrum Networks Ptd.

>LR range SFP + mikrotik
by Mike Everest 16 Nov '15

16 Nov '15

Hi All! I receive questions from various folks from time to time who need to take advantage of dark fibre runs > 20Km. I have already received confirmation from MT that none of their products currently support power required to deliver greater than LR modules, so I suppose that the only option is for some kind of third party switch or media converter would be required when using MikroTik routers at the endpoints? Here is a query I received this afternoon: "What are after is integrating a 45km Single mode dark fibre into our network, obviously mikrotik routers on each end. If we could push 10Gbps that would be awesome, however if we could obtain 2 or 3Gbps with a lot less effort that would most likely be the go to start with." Does anyone have any suggestions for the OP? (I suggested that he post here, but perhaps he's a bit too shy to post in a public forum, so I offered to ask on behalf ;) Any comments will be most appreciated! Cheers, Mike.

BGP and CCR
by Daniel Hoffman 13 Nov '15

13 Nov '15

Hey All. I know there are promises in ROS7 for better BGP performance but the CCR and the ever slow BGP is starting to grow very tired for me. Waiting 5-10mins everytime you change a filter or update a table is coming more than inconvenient. That being said, I see only two options available to me. 1. RouterOS on x86 and to look at a dual core system with a high clock speed in the 3Ghz range, however I have to be very careful around support/capability of disk controllers and others or I might end up with 6 machines I cant use or have to run it inside a VM. 1.a is RoS X86 still oly 32bit so limited to 4GB RAM? 1.b Anyone have any known good configurations with high CPU configs and dual power? 2. Swap to Vyatta/Brocade which is not really something I want to do, but if I have too I will. Advice/Experience appreciated. Thanks Daniel

Omnitik Half Duplex Issue
by Paul Julian 12 Nov '15

12 Nov '15

Hi guys, a while back I asked the list about the issues we seem to have with Omnitik 5Hnd units and them randomly syncing up in half-duplex 10M, I have exhausted all options with these and after just having yet another one do it I am at my wits end. It doesn't seem to matter whether you use auto-negotiate or try and hard set the interface speed on the device itself or the device that plus into it but they just randomly decide to go to 10M half-duplex, has anybody else seen this and come up with a concrete fix by any chance ? It only happens on Omnitiks and it seems that it's only on the ether1 port from what I can see. Regards Paul

Compatible OpenVPN Server
by Stephen 09 Nov '15

09 Nov '15

Hi all, Just wondering if any of you can vouch for particular VPN providers that have OpenVPN that actually works with the Mikrotik implementation? I've tried both PIA and NordVPN, but both are incompatible for various reasons. I'd also prefer to stick with providers that have reasonable policies of privacy, but I understand if privacy vs. compatibility does not exist (as per HMA). Thanks in advance! -Stephen
