Thank you for your answer.

ChrisVanMeer

Hi there,

Does anyone know what the limit of the routing table is on the CCR1072-1G-8S+ ?
For instance, my current HP HSR6602 can have 4 million routes at max.
I am looking to replace this HP with possibly the 1072 as BGP router.

Hope to hear from you!
Chris

Nobody?

Hi all, I have two identical 3011 units that operate in a twin datacenter setup with VRRP. Last week there was a (scheduled) power cutoff at site A, the 3011 there went without power. No problem, it got back up once the power was restored. But since then there are four SNMP values that aren't availa...

ChrisVanMeer

Sorry, my bad....just got out of bed lol.

ChrisVanMeer

Maybe it has something to do with the following (at least, I had this issue in a simular situation). You have two IPv6 addresses that are in the same /64 (fd9c:944d:aa3:3342:192:168:0:254 and fd9c:944d:aa4:3342:172:16:1:1) Could you try to make the fd9c:944d:aa4:3342:172:16:1:1 a /128 and check if t...

ChrisVanMeer

Could you post the output of the following command:

/ipv6 export

ChrisVanMeer

Wow thanks, actually all those points make total sense.
Strange is, the if statement without the : did work.
I have changed the script accordingly and all is still working as expected.

Thanks a lot!

ChrisVanMeer

Hi guys, I made the script below, that is in production. Basically what it does is check the routing table for routes in a given subnet, if no routes are available, make the vrrp-instance go to backup-state. Could you guys look it over and see if there is any optimilization possible, or maybe someth...

ChrisVanMeer

Just wanted to let you guys know that I have succesfully replaced the Cisco 3750's with RB3011's.
The processor utilization never raises above 7% and all the QoS is handled perfectly.
Thanks for all the help.

ChrisVanMeer

I got two after two weeks waiting in The Netherlands

ChrisVanMeer

I have solved the problem, thanks to this topic.
After changing the VRRP IP to a /128 (and not advertising it) on the master, the host address + the vrrp ip became reachable.

ChrisVanMeer

And the weird thing is...I recreated this in GNS3 with CHR and the exact situation works as I wanted (vrrp + host address).
Same firmware level (CHR en RB3011), so I don't get why this doesn't work on the RB.

ChrisVanMeer

Your assumption is correct, it is indeed a transit network with 3 routers (2 RB3011's and 1 FortiGate). I know OSPF or BGP would be "better" but this installation, the routing back to the RB3011's has to be static and to one IP only. That's why my choice was VRRP-v6. You mean I have to rou...

ChrisVanMeer

Weird situation going: 2x RB3011 connected through a stretched VLAN. ether1 goes to the WAN and ether10 is connected to the datacenter. I have a VRRP interface (called vrrp-v6) running on both RB's, on ether10. Just like with V4, I configured each RB with 2 IPv6 addresses: one for a "host"...

ChrisVanMeer

Are you managing the CCR's through SSH? In that case you can use the tool "dsh" to send one command to a group of devices you can define for yourself. It is not meant as a way to synchronize your current configuration, but it might help you with future management through SSH. Google for &q...

ChrisVanMeer

Ok thanks

ChrisVanMeer

Maybe, I have sent support an email with a graph, this URL and the supout file.
Will report back when I hear from them.

Hi, I - by accident - discovered something weird with my CRS125-24G-1S-2HnD. Every couple of hours, the temperature spikes to 60+ degrees Celsius, and then the next check (polling interval of one minute), it's back to normal.

Hi, Can anyone tell me if there is an OID for the "friendly" name of some models? Currently I use SNMPv2-MIB::sysDescr.0 to get the model name, and it works. But in the case of a hEX or hAP, I would like to see those names, in stead of RB962UiGS-5HacT2HnT (hAP ac). I tried an snmpwalk on a...

ChrisVanMeer

Yep, tried that as well.
And if it was the solution, then it wouldn't explain why the wired devices on / behind hEX1 have lower speed than wireless devices behind hEX1.

ChrisVanMeer

The hEX2 also has an Apple TV (gen4) attached to it, it gets the same speed. But connected directly to the switch, it gets up to 100 Mbit. Same goes for the Pi, so the hardware can handle it. Something on the hEX is slowing it down. Another thought: iPerf's from Pi2 and Pi3 to Pi1 shows 94Mbit, but ...

ChrisVanMeer

http://wiki.mikrotik.com/wiki/Manual:SNMP#Management_information_base_.28MIB.29 By the way, if you have a certain value in Mikrotik and you want to find out the available OID's do the following: Let's say that you want to find out the uptime, mem, etc. /system resource print oid uptime: .1.3.6.1.2.1...

ChrisVanMeer

Hmm, when I do a quick compare between my MikroTiks, it appears that both hEX's have an input voltage of 11.5V.
The rest of them has 24V.

Does the input voltage has anything to do with the throughput speed?

ChrisVanMeer

Could you post the output from
/ipv6 nd export

ChrisVanMeer

I can't get why a pi connected to the crs125 is doing fine and when I connect that same pi to hEX1, speed drops. Both ports came up as 100mb no errors.

And the iperf from pi2 and pi3 to pi1 get the full bandwith.

ChrisVanMeer

Yes swapped hEX1 with 2. Swapped the power supply.

Didn't swap the cable, it runs through the walls...but my theory is that the cable is good, since my laptop gets high speeds through wifi that is connected to hEX1

ChrisVanMeer

Ok, moved the IP addresses of hEX1 and hEX2 from the bridge interface to the ether1 port and then removed the bridges. The reason why I created those bridges? I don't know really, now to come and think of it. Removed SFP1 from the CRS125. No change in speedtest-cli outputs. CPU speeds stays low. Yes...

ChrisVanMeer

Thanks for the explanation, pe1chl.
So maybe the current config of the 3750's aren't even handling QoS as effectively as possible.
However, I have no complaints from the people who use the phones.

I will use the provided script to create the mangle rules and the queue tree entries.

ChrisVanMeer

Thanks!

ChrisVanMeer

That's good to know

Hope I can get my hands on two of them quite quickly.

So, regarding to the uploadBandwidth, should I keep that at 4200k, or amp it up to a larger number?

ChrisVanMeer

Oh and how did you choose the uploadBandwidth?
In your script it says it's 4200k, but is this a number that is known to be good with VoIP?

Or does this number correlate with the WAN speed?
If so, what number should I choose for a 50Mbit WAN uplink speed?

ChrisVanMeer

Thanks David for clarifying. Actually, we use HP 3600 switches at the Branch office, where all the IP phones are connected to, so I think there are just 8 levels used. I was thinking of replacing the Cisco 3750's (WS-C3750G-24TS-1U) with 2 RB3011's. In my opinion, the RB3011 in hardware specs is muc...

Hi guys,

Does anyone know how to convert this Cisco entry

Hi, received my new unit today. Serial number 6737063D345F, but whatever I try, inter-switch connections are fast, from switch to uplink (all connected with gigabit cable) throughput remains 30-40Mbps.... So it didn't solve my problem.

ChrisVanMeer

Windows "teaming" == Mikrotik "bonding"
What you probably have to do is first, remove port ether4 and ether5 from the bridge.
Then create the bond interface. Afterwards, go back to the bridge ports and add the newly created bonding1 interface.

Did that help?

ChrisVanMeer

See this link it helped me a lot.
Not neccesarily just for wireless, you could replace wlan1 with another etherX port and skip the wireless settings.

ChrisVanMeer

hAP AC looks fine after upgrade.

Did you experience slow ethernet connection prior to upgrading?
If yes, do you notice improvement after this upgrade with ethernet speeds?

ChrisVanMeer

Had brief contact with Mikrotik support and they adviced me to contact my reseller for warranty. They will ship me a new unit at the end of this week, which I can try out and then send back the old one. Great service so far, I hope the replacement unit will clear up the issue. I will let you know th...

I've just wrote to support, same issue here. WIFI great performance, but ethernet connection speeds are 40Mbps max.

Thanks for the remark. It appears I wrote it up wrong.
I have it set as 20Mhz Ce, not as 40Mhz Ce.

And I have the CAP's set to local forwarding.

Ok ik already put the uplink of the 2011 in the same bridge as the other ports including the wlan1 interface (except the wan uplink) and I will bridge all ports in the hAP as well, so that would cover the 5GHz part.

But how can I use both RB's as AP's for the same SSID on 2.4Ghz?
