Now I know why everyone was saying - its probably an MTU problem no matter what doesn't work in MPLS. Because it probably is

Take note: Don't buy Tripplite fiber media converters - they only support 1504 MTU. And x86 routers just don't play well with MPLS. Two lessons learned so far...

Thanks for those who have taken the time to help out - we appreciate it. Ok, so we have made lots of progress.

We are seeing the same issues with the 2011 new routers we have. All ports go into switch mode and router is not visible via winbox or IP neighbors from adjacent routers.

STE,

Would you mind shooting me an email outside this forum please. I would like to ask you a few questions regarding our post here.

Thanks scott at flhsi dot com

CarulloS

Furthermore... are you telling me that setting the flagship routerboard gig port hard set to 1000fdx is not an option? I've never had that problem with any other GB router or switch ever. Please clarify maybe I misunderstood what you were trying to say. Thanks.

Scott

CarulloS

Well then I think you would agree if it HAS to be on to work then I should not have the option to change it and lock the router up... Do you agree?

Scott

I can safely say that you are probably the only person on this thread using a 133c with 4.x and nstream on a ptp link. Problem still exists for the rest of us.

Scott

CarulloS

Scott

CarulloS

A lot of people have problems with nstream and 4.x not just the small number of people on this thread. The list is much larger... Mikrotik's consultants know about it too and they work with lots of people consulting with MT.

Scott

CarulloS

Its about time for a MT rep to chime in again on this as we have heard nothing for some time.

You guys send some emails with info to support to might help get some quicker attention as well.

Scott

CarulloS

Well they just came out with upgrade today and it doesn't mention anything about nstream. As far as I know a problem has not been acknowledged even though many users have reported the same findings... Hopefully some day the results will be better.

On a dual nstream setup I know you set one card to tx and one card to rx on each end on different frequencies.

One thing Nick didn't mention was the fact that 100% of our upgrades from v3 to v4 failed with WAN disabled.

I hope MT does not try to add any PBX related functions in their ROS. My opinion. If you want to do this run linux in a VM and do what you like.

Scott

I'll make an educated guess as far as the power goes with the N cards... With one chain (antenna) output at say 9db - add another chain with equal output you end up with 12db (not 19db) Anytime you double your power you get 3db more gain / output. I believe that's why you can only get the max power ...

CarulloS

I should have mentioned... Just use EOIP or another alternative to WDS with N, does the exact same thing functionally and works perfect.

Scott

CarulloS

Write off WDS and N its slower than not using N so there is no point. Either use WDS and B/G/A or use N without WDS. After testing it I can tell you they don't mix.

I don't have evidence for certain, but I can say that I feel the same as ste... 3.7 solid everywhere. I skipped 3.8 because of horrer stories. I have 3.9 on new rb411s without problems but I've had problems with 3.9 on rb500 boards with daughterboards that work fine with 3.7. If their change log is ...

CarulloS

Some of the previous posters are mistaken... You can have 10 ethernet ports working in a MT router - even more if you wanted. It all depends on your hardware selection and bios options. I have a server with 10 ethernet ports and it has been running without a single hickup since I turned it on. Super...

CarulloS

Of the last 7 rb411s and 411As in the last few days (since my previous post) I had another board run about 5-10 minutes then go dark with no minipci card installed. The other 6 work fine.

Scott

CarulloS

Anyone else have feedback either way on this topic. I was going to deploy some new rb411s with 3.9 but I don't need to cause myself unnecessary pain and suffering.

Thanks,
Scott

CarulloS

Implement layer 7 packet marking and que the traffic so you can control it.

Scott

CarulloS

Also make sure you are not blocking broadcasts between your routers. Some rules or radio links block broadcasts and that will not allow ospf to work.

Can you show me a circular 23+db antenna for 5ghz?

I already had/have HPOL and 28db Gabriel dishes...

CarulloS

The signal is already about -50 when its good - like now. Last night same link was hitting -90

Unique problem

CarulloS

I have a link over 17 miles of open ocean. 5Ghz/10Mhz The link fluctuates significantly in signal strength. One second its -60 and a few seconds later can be as high as -90. Thats pretty extreme. I am confident its not interference -induced because if the history with the link (hard to explain). Any...

CarulloS

I never have problems with all my other links too - just this one. Swapped out one side today - antenna - cable radio card etc... will see.

Scott

CarulloS

In my case I tried every single freq there was on 5ghz even with superchannel. No matter what I chose it worked great for a while then crapped out 6-24hrs every time. Then I could go scan or mess with something and it would come back up. This one has just been weird.

Scott

CarulloS

I have two hotspots - one running rb411 with xr2 and one rb532 with sr2. I have the same configs elsewhere but these two hotspots in one particular area are slow to the users and the cpu is unusually high (50-80 most of the time). There is a lot of other competing gear in the area where these are lo...

CarulloS

I can't offer any suggestions but I'll add I have a new link with RB411s and XR5s p2p and I have similar issues. Works about -55-60 perfectly 30mb throughput and after a day or so craps out disassociates. I play with it comes back for a good while and goes downhill again. Not sure this has any relat...

CarulloS

In winbox / click new terminal button, get this:

MikroTik RouterOS 3.9 (c) 1999-2008 http://www.mikrotik.com/

could not connect to console, try rebooting the router

CarulloS

There was a problem with RB150 firmware. Was that new working fw for the board included in this release? Didn't see in release notes.

Thanks
Scott

CarulloS

Modify your scan list as well...

Scott

CarulloS

Yeah, thats why the last 100 routerboards worked just fine. I program every one on the same desk with the same supply. I'm not asking for help, I am trying to find out if this was a fluke or a problem I need to be concerned with. I'm not jumping to conclusions. I've seen stranger things.

Scott

CarulloS

I hope I just got lucky with the odds that out of the last 5 RB411 boards I purchased that two are doa. One shot a spark out when it was plugged in the first time near or at the 2R2 tiny transformer doohicky (right between C825 and L801) - of course after that there is no sign of life. The other one...

CarulloS

Thanks sergejs, If you wouldn't mind taking an extra few seconds to tell me how to use the reset button procedure to do what you asked that would be appreciated. That or point me to the actual page that already has the info. I just searched through routerboard.com as directed to no avail. Normally I...

CarulloS

I read recently (I can't find it now) where someone had a problem upgrading the firmware in the 3.7 release on the RB150. After upgrade RB doesn't boot. I am confirming same behavior. Apparently they said ros3.7 wasn't the problem, it was the latest firmware in the 3.7 that caused the problem. I hav...

CarulloS

Yeah, one ethernet and two minipci would handle most of what I need.

Maybe the key is to get pac wireless to make a DCE 10x6x2

CarulloS

One of the previous posts raised a question... I was sort of imagining the RB433 being about the same size at the 133. Is it in fact the same size as the 333? I hope its not laid out like the 333, its my least favorite so far of all the designs. Also a quick question if I can slide it in here... Wit...

CarulloS

Actually since my original post I figured it out. The XR5 works great all all 5Ghz freqs I can attest to because I tested it today. The reason it would never assiciate was related to the scan list contents. You have to manually modify the scan list in order for superchannel wireless links to asociat...

CarulloS

I'm not sure what the problem may be, but in superchannel with XR5 I can only get normal 5Ghz freqs to associate. Anything in the 547-5725 range doesn't associate. Does anyone know what could be causing this?

Thanks,
Scott

CarulloS

Glad it works, I'll have to try it again with another rb and the latest os.

Scott

CarulloS

I was mostly concerned with BGP behaviour... I have OSPF working fine across the board and I make changes regularly. I have 2.9.50 and 3.7 mostly, with a quagga or two in the mix.

I need to upgrade a bgp router and are considering options.

Scott

CarulloS

I will have to upgrade a router soon. Should I use MT v3.7 or go with quagga? Its been a while since I asked or saw feedback with current version. I need two full feeds from two upstreams and one internal interface with OSPF advertising default route. I am not redistributing BGP routes into OSPF - o...

CarulloS

Have these shipped to anyone yet?

Scott

CarulloS

Would someone with a voltage meter and a board handy test this theory

CarulloS

Thats awsome...
Thanks for bringing that to my attention

Scott

CarulloS

There is a lot of p2p traffic that can be caught by l7 that slips right through the built in firewall filter. I would consider any l7 filter an advanced application

Scott

CarulloS

It would be very nice and powerful feature to activate firewall rules & mangle rules based on time of day and day of week. You could then very easily classify traffic different for the business/evening/weekend crowd.

This would help us a lot.

Thanks,
Scott

CarulloS

Would this cause any side-effects or just block all p2p traffic except http type?

All outgoing requests from hotspot users should be going to ports < 500 for the destination for any standard service correct?

Scott

CarulloS

Ok, so it doesn't really matter... But for curiosity sake does this mean that all the ones moving forward will or will not have heatsinks?

Thanks for the reply normis...

Scott

CarulloS

The document you referred me to is about gateway load balancing with route commands. My question only involves ospf equal cost routing between two routers without the need for a gateway.

Scott

CarulloS

I have three routers in this scenario (that matter). Routes are for A-B-C and A-C By default with costs of 10 for each route, all traffic from A going to C (and vise versa) go direct and not through B because the cost is 20 with 2 hops instead of 10 with one hop. I have taken the costs from A-C and ...

CarulloS

Some of mine had them, some didn't - same distributor. Thats why I was curious what others were seeing.

Im in the US

Scott

CarulloS

Ok, whats the deal with some RB411s having heat sinks and some not. I assumed at first that the first batch with L4 license didn't have them and it was added to production released boards due to the better reliability of having it. That must not be the case because I received new ones again without ...

CarulloS

I'm guessing its not really related to ROS 3.7

I have many x86 with both those versions and never had this problem.

Scott

CarulloS

I've been using some rb411s for backhauls and have been getting about 35mb tcp throughput. From rb411 to RB411 the speed in btest will should between 25-30 but running pc on each end real traffic between 30-35MB.

Thats a great deal for <$500 complete link with full management...

CarulloS

Send supout to support and they will make that card work if it doesn't currently.

Scott

CarulloS

3db more isn't an assumption - its a fact.

CarulloS

I got 40+ in bridged mode between pc and laptop with btest. When switched the two ports into switch mode (set port b to master a) I got xfer rate of 80+

fyi...

Scott

CarulloS

This entire topic is useless except as the subject implies you can use ports of some rbs as switch ports that do indeed operate faster than when just regularly bridged. Once you set a master port on the rb and put certain ports into switch mode you ---> can not <--- add an ip to them or otherwise us...

CarulloS

realistically... I doubt it. But I still think its the best practice to ground it all. Pac wireless doesn't have pieces made and shipped that cost them money if their engineers hadn't designed it that way for a reason. It does not take a long time to drill 4 holes and tap them with a drill. Maybe 2 ...

CarulloS

I've also noticed with nstream if you don't have any traffic the link disconnects and reconnects randomly over time. Put a load on it that goes away.

Scott

CarulloS

Forepoint... You do not have to thread the hole if you don't want to, just drill a hole (or use pre-driled in like arc enclosure) and put a nut on the back :) Travis... If its working for you then I wouldn't make a deal over it, but here is my opinion: The radio will be grounded via the poe power (7...

CarulloS

I think you meant to say every 3db you double your range. But in any case, you double your power not your range necessarily with each 3db. I've never had a backhaul where 3db was a make or break, and certainly not had the luxery of of using twice the tower space. Safe margins are like 10db so having...

CarulloS

anytime you use two antennas stacked in phase properly you gain only 3db above a single antenna. If 3 db makes that much difference you should condsider shanging something else to improve the link.

Done incorrectly it will cause you more problems than it would have ever solved.

Scott

CarulloS

I need one - do I want the newer via chipset card or the older realtek one? Same price, whats your feedback?

I leaning towards the via unless there have been problems...

Scott

CarulloS

I tried to test it like this - did not work for me.

Scott

CarulloS

Support emailed me and said that so long as you don't have a wireless card in the rb600 then you can use the daughterboard without ptoblems. They said you can use the wireless slots on the daughterboard however. They said they are still working the problem.

Scott

CarulloS

Janisk says use one version over all routers, as there where some major OSPF changes. If you can check if you can successfully upgrade to 3.6 all your routers as this is IMO most stable OSPF ever in routeros. Are you referring to running v3 on al routers talking together or are you talking about 3.6...

Great - thank you for your input. SO in your opinion the RB600/564 combo is good to go and ready for production tower deployment - routing only...

I'd like to augment this question with the following: Has anyone used this daughterboard with the RB600 just as ethernet interfaces and had it work the way it is expected to? I'm going to assume that the problem experienced in this original post is from a overdose of radio cards or some power proble...

Thats like asking if there is an 18 wheeled 800HP diesel version of a vw bug available one day.

No. But there is a RB333 and RB600 that are available that are what you just asked...

And... you can upgrade the license on the RB411 to whatever verison you require.

If I take a laptop and load ROS 3.6 on it with pccard from the supported list will MT find and configure it as an interface upon installation? If yes does this mean I could take an old laptop and place it at a customer site and give them internet via a natted ROS router (the laptop)? That would make...

CarulloS

I thought there were some issues using that daughterboard with the rb600 though? I read it somewhere in here that it was said not to use it. What has been your experience using them together?

Thanks,

CarulloS

I have a need for many routerboards with more then 3 ports. The high-end 4 port router cost prohibitive for what I need and overkill speed wise. I was using RB532 and daughterboard for 9 ports at tower locations to act as router for ospf and some ports bridged together for local APs to plug into. An...

Maybe need to start drilling down on the vista version and the nic/driver versions to see if there are similar conf...

CarulloS

Doesn't matter, I use it like that daily... It's an isolated problem he has

CarulloS

Last time I assumed that neither of them worked - the trango killed the mt and the mt put some suffering on the trango too - neither happy.

Thats why I am interested in how your tests turn out. This was a sr9 though not a xr9 and I only tested once.

Scott

CarulloS

I know you can colocate trangos - I meant utting a xr9 in the mix - how does that work?
