How is MPLS over GRE supposed to work anyways? MPLS relies on injecting labels between MAC and IP. That's why it is called Layer-2,5 sometimes. GRE-payload is IP only, so I don't see a possibility to transport MPLS labels to establish an LSP. However it will work with proprietary EoIP, which is some...

As long as there is no packetloss TCP will scale up the bandwidth even on high latency links.

But every tiny bit of packetloss on high latency links will kill throughput.

Try this on DHCP-Client:

special-classless - adds both classless route if received and default route (MS style)

Mikrotik has confirmed that this is an issue with neighbor discovery.
But since they assume that this is just a cosmetical issue, a time/date for a fix of this issue will be in the far future.

Hi All,

My RB2011 showing high CPU load 100% and when i check in tools - profile the DHCP process is consume CPU more than other process but the weird is no DHCP setup on my mikrotik, for reference i'm attaching the screenshot of my mikrotik dhcp cause cpu high.JPG

RouterOS Version 6.1? Really?

sup5

Already done.
All MACs are unique

sup5

I've got the same problem. STP definitively BLOCKs the Loop in my infrastructure. The message "bridge port received packet with own address as source address" disappears as soon as I disable neighbor discovery. So I suspect that either Neighbor discovery is broken, or that STP-Blocked Ports still tr...

I am sitting between the chairs with Mikrotik Hard- and Software: On the one hand I get an extremely flexible and cheap product. Also software updates are regulary and bugs are often resolvend in a manner of weeks (occurence of the bugfix in rc) On the other hand the quality of Hard- and Software se...

How does the discussion about beta firmware relates to rf irradiation issues? The regulatory authority claimed (in my case) that some sort of bad/wrong rf besides the main signal is being radiated by the device. I think this kind of issue is not fixable with firmware. It seems to be an hardware rela...

I received a similar letter from the german regulatory authority (BNetzA), which says that the SXT-ac must not be sold, handed over or imported. The german letter referred to findings of the above mentioned spanish authority. I sent this german letter to MikroTik several weeks ago, but a statement o...

sup5

But still, it would be nice to investigate the issue the OP raised. Bugs always should be considered checking.

sup5

It would be nice to have the option NOT to restore or backup MAC-addresses on HW-interfaces (Ethernet and Wireless).
Restoring MAC-addresses of logical interfaces like bridges, EoIP, VPLS and the like is useful though.

3.Is it possible to use CAT.5E cable to link with 10GBASE-T? A: No. The standard bandwidth of CAT.5E is 100MHz, and CAT.5E is designed to transmit signals below 90M. 10 Gigabit signal transmission requires a CAT.6A patch cable. 10GBase-T will work even with Cat5e as long as the distances are short....

sup5

Uhm, none...

sup5

Maybe pulling one VLAN trough the slower link and two VLANs through the faster link.
Then make a 3x bonding out of all three VLANs.
That would make up for a 2:1 load balancing, which roughly meets the 50/32 ratio.

sup5

When an ARP entry is present in the ARP-table, one can surely assume that a given IP address is being used.

sup5

You might create a temporary workaround by setting up an EoIP or VPLS tunnel over the wirless link.

Both tunnel types support fragmentation and reassembly

sup5

you should probably try to segment your networks in order to increase security and stability.

It is not best practice to host more than 200 clients per broadcast domain.

sup5

I think, you got your subnet masks wrong.
VRRP-Interfaces always should be configured with /32

Please paste the wireless configuration as well as all used device types (AP and Stations) including their full product name.

It works, if you set it up properly:

It seems they are missing galvanic isolation. Do you even electric? :) Galvanic isolation is broad term for anything what physically isolates two circuits while maintaining signal transmission between them. For example every gbit poe port must have galvanic isolation to separate power from signal w...

Mikrotik devices simply are NOT fully 802.11af/at compliant.

They might be compatible to some switches, yes.
But they lack the support of all requirements.

It seems they are missing galvanic isolation.

Ignitnet 60 ghz solutions have the 5 GHz for backup I hope that MIkortik in near future develope a similar solution For that price, why not just put a second link with a couple of SXTsq Lite5? Because that means: 1) add another router (i.e. HexPoE) to each site to maintain the redundancy functional...

Antonsb I hope you are true

And I hope to see a version with integrated 5 Ghz backup

Seems to be already prepared in WAP60G and LHG60G. Just missing the Amplifiers and Internal Antennas.

Today I opened the WAP60G. It seems that 802.11ac Wave2 2x2 MIMO already has been prepared on the PCB in terms of missing amplifiers and antennas/connectors (labeled CH0 and CH1) for the 5GHz band. Have a look at the pictures below. So it could be possible, that we would get a future RB-LHG60G5HPacD...

Is there any chance to overcome 3000 meters?

sup5

I made quite good experiences using PLC stuff. If done right it works better than WiFi under certain circumstances. I once lived in a flat, where plain wifi was nearly impossible between rooms, due to overcrowded spectrum in 2.4 as well as 5 GHz bands. The only possiblity without putting in new netw...

sup5

PWR-Line devices don't work this way.

They work more like WiFi using OFDM. -> Many small QAM carriers.

HomeplugAV200 uses OFDM carriers between 2 and 32 MHz.
Newer HomeplugAV standards extend to 85 MHz or more.

Quality Brands will apply a PSD-mask to their devices to circumvent the 27 MHz ham band.

That's the product specification.
Get another routerboard, if you need more speed than FastEthernet allows for.

I'd recommend the HAP ac.

Imagine, you're left with the non-DFS channels 36, 40, 44, and 48. But you want to setup a WiFi-System using 80MHz Channel Bonding. As simple as in the 20MHz-channels-setup you'll evenly distribute the four primary channels. But with 80MHz you have four options sharing the same Bonded-channel: Ceee,...

sup5

Just use the Keepalive-Feature.
A unreachable tunnel-endpoint results in a non-running Interface state.

sup5

I'd like to see a bare distance vs. throughput/MCS table in order to be able to estimate possible use cases.

sup5

You need to use SRC-NAT to rewrite any connection initiated from the router to one of the Public adresses of the route Subnet.
In order to save addresses, I would abuse the very first address of the prefix, which is unusable within standard ethernet (Network address)

sup5

So now you should find the cause within your network.
I suspect you've got multiple links to your internet gateway and forgot to configure a VLAN on one of the links

A simple STP-topology-change would never bring any services down, if the network was set up properly.

sup5

I guess, the 'station router' is a non Mikrotik-device?
Then you cannot achieve transparent bridging. Thus the MAC-adress of the clients will be MAC-NATed to the MAC-address of the 'station-router'

sup5

@webfixnow: It might be the case that the wap-60g alters your (R)STP Topology (you might have forgotten to configure a VLAN on a fromery blocked link). Set the STP Protocol-Mode on the bridge of both WAP-60G to "none" and try again. @Normis/Mikrotik: according to the default-configuration script thi...

As a general rule of thumb:

Always inform support about bugs. Do not rely on the forums.
Shrink the setup to the bare minimum in order to exhibit and reproduce the bug.
Add Diagrams and PCAPs etc.

Any bug I informed support about so far has been fixed.

sup5

Briefly explain, what you are trying to accomplish.

After a quick conversation with support, this issue was resolved within a few days in the latest release candidate:

I cannot contribute to this issue, but still I am curious:
What's the point in adding twelve LTE-Modems to a router?
Better coverage by using multiple ISPs?
Load distribution?
