ok I see. that's too bad we don't have a switch like the CRS317 in the middle

I will try for now to play with the CCR2004 and use the 100G switch only for the transport then.

benoitc

I am thinking to use this swithch as a simple gateway MPLS + OVPN and simple L3 routing. Did anyone tried it for such purpose. How does it performs? . Indeed there is a very small amount of RAM on this switch compared to what has the CRS317 or what others do on the market. So it's surprising for thi...

benoitc

ok ... so that's probably mean I will have to use MPLS waiting for it :/

benoitc

Has anyone tried to setup a vxlan between a mikrotik switch and an arista (or cisco) switch? I don't see any remote ip setup in arista documentation. Would the command [ICODE]flood vtep[/ICODE] works in such case?

benoitc

With this option can we imagine to setup a vxlan over the internet with a higher MTU ? Would it ref-fragment it when it comes?

benoitc

ok I see, wondering if someone tested this setup and provide some feedback though.

I think I ma have been interesting to provide a shelf that allws to put the power input and the router on it (or é routees) that would be awesome

benoitc

I'm interested by putting the 4 RB5009 I have in 1U but hI am wondering how much the heat is dissipated. Do you think it will be OK in the summer ? For example would it work in room between 30-35° ? (which can happen when the AC fails or it's too hot outside). Any feedback i welcome.

I have setup one router with a simple BGP mulihoming with 2 ISP and failover by dapting the scenario in the wiki: https://wiki.mikrotik.com/wiki/Manual:Simple_BGP_Multihoming for routeros 7.

I have a core router that does BGP multi-homing . 2 ebgp sessions using 2 ISP. The router correctly received its default route.

benoitc

Is GRE is offloaded on the CCR2004 series? If not should I expect the same impact on the CPU load with the CRS317 switches?

benoitc

i added more info to the support and will close this topic. For the record i had an ip wrongly set a loopback bridge instead of the interface. This was creating a loop and only one core was used 100%. which was for some reason blockings other tasks while routing was still OK... Anyway if it alao hap...

benoitc

Now, you can synchronize static leases (using some script that exports relevant configuration subtree on both servers, merges it and uploads resulting file to both), but it's not possible to do it for dynamic leases (and I personally don't see a point in doing it). hrm OK, but then what should be d...

benoitc

Is there a way to synchronize dhcp leases between 2 nodes in HA (or using OSPF) ? Should I use an extra aggregation layer? Same for IPv6 how to ensure if one node crash that others keeps their IPs (or get a new one?

benoitc

in the RB5009 they are using a CRS317 fo link the 4 r b5009 I believe. But I'm thinking to use 4 porta on the ccr2004 that is already connected. Would it work enough fast?

benoitc

Yes, Ubiquiti 24, 48, and 50-55V POE injectors should work just fine, depending on the load you plan to draw. What's wrong with the provided power supply? You could easily cut the DC plug off if you needed to wire it from the side instead of the front. well nothing wrong :) I am just trying to get ...

benoitc

So would the Ubiquiti Edge Power 54V/150 W [1] works to provide supply to 1 or 2 RB5009UPr+S+IN connected using WAGO in // ?

I can't stand those bricks so picked up a Mean Well DIN power supply ( HDR-30-24 ) and a rack mountable DIN rail ( WatchfulEyE DIN Rail ). probably a stupid questio, but what DC output would be more efficient: * 48 VDC, current range ~0-5A, peak 7.5A * 24 VDC, current range ~0-10A, peak 15A I think...

benoitc

A multi-dc outlet would allow me to plug it to the UPS easily. Taking the PoE path means only the power delivery device needs UPS power. A nice bonus falls out of this if you were using the fiber port on the 5009 as the LAN core uplink. While you might be tempted to reject this idea since you can't...

benoitc

i'm wondering how much the system can resists to power overload and how balancing between the 2 power input works on the ccr2004-16g-2s+.

benoitc

one thing annoying using the 4 rb5009 in 1u design is the position of the 2-pin input. There isn’t a lot of room to put a cable for the one at the bottom right (front view)… Would have been better to have them in front…

benoitc

Regular static route, where gateway is link-local (fe80:...) address of target machine.

thanks!

benoitc

Is there a way to route correctly an IPv6 /56 prefix to another machine without using DHCPv6? The idea is to route this prefix to another interface and then from then send /64 addresses to pmahines connected to this router using RA. Any hint is welcome

benoitc

anyone?

benoitc

RB5009UPr+S+IN can be powered by 3 different ways: DC barell jack, 2-pin terminall and PoE-in. However it seems that if PoE-in is active power source, PoE-out is disabled.

I will test it but did you have a source for this. This is very interresting

benoitc

I used this 48V 3A power supply: https://www.amazon.com/dp/B07G21P3KD Coupled with these DC splitters: https://www.amazon.com/dp/B07J28SX6Y The power supply goes into one splitter, which feeds to two more splitters, and each splitter goes to a pair of RB5009's in the rack (two on the left, two on t...

benoitc

I'm not a pro in that domain. I am wondering what would be the best way to power in the office the RB5009UPr+S+IN so it can resist to power outage and go on the battery if it crashes. Any idea is welcome. So the main connection right now is handled by a CCR22004 dual BGP homed that is plugged to two...

What is the command in router os 7 that is replacing `set-in-nexthop-direct` ?

benoitc

CRS is a switch

CCR is a router

what does it means? today we see more and more L3 switch, same for the CRS with routeros. So how it differs there, what performance improvements in L3 brings the CCR2004 vs the CRS317 with L3 offload?

benoitc

The L3 HW offload feature are supported on the CRS317-1G-16S+ but not on the CCR2004-1G-12S+2XS. Is there any reason to still use the CCR2004 then if we don't need the 25G ports? My use case is quite simple: I have 2 links one with PPPOE, one with a GRE tunnel on it on which i get a 1 /48 IPv6 and a...

CAT12, CAT16, 5G. Due to lack of modules from Mikrotik I was forced to get Quectel EM12-G on my own to get decent speeds.

Did you put it in a wAP ? Do you have any doc / post about it?

benoitc

wAP 5G powered by POE or DC with a little more ram / disk space would definitely make my day :)

benoitc

I like the RB5009 for its ability to be powered using multiple source. This make it really useful. Unfortunately we doin't find such hability on chateau devices. An the wAP ac LTE6 kit is limited to LTE6. Can we expect to have an LTE/5G device with multiple power inputs soon?

benoitc

Other than that routing is just routing so if you have done this with ipv4 you should not have any issues with this

Right, but not sure that performances are the same. It seems that everything in IPV4 is offloaded but nit with IPv6 . At least on the CCR2004. But maybe I'm wrong?

benoitc

The questions a good start but a bit broad, are you able to give us an idea on the end functionality, do you want specific services to only go out one ip, do you just want it per connection, do you want to bond the interfaces and improve the throughput etc. There are many different ways to set this...

benoitc

On a CCR2004,I have setup 2 WAN (2 different lines/ISPs) for IPV6 failover using BGP. Failover is working fine but I know would like to fully use these connections. Is this possible using internet rules? Or should I use 2 routers each connected to a different ISP?

benoitc

Seems to not work. A DAC is working but not when using an optic. The Mikrotik doesn't detect the SFP28 and try to use it as QSFP28 module so the memory space is not the same and DOM is not read correctly :/

benoitc

on wich version?

benoitc

Mikrotiks and various other devices support /32, you can use any local address on the Mikrotik for the CCR end and one of your spare public addresses for the machine end.

Routing or Switching ?

If switching
How about the CSS610-8G-2S+IN ?

It has 8x 1Gbits and 2x 10Gbits
The only disadvantage is the Swoslite

I meant switching sorry (i fixed it). CSS610 is only 1G though, isn't it?

benoitc

For a project I need to be able to switch max 8 ports at 1Gbps or 2.5Gbps and connect the switch to to two 1OG routers.

I am tempted to reuse the CRS317 with an RJ45 SFP module, but would it requires to have empty SFP+ slot between connections? Is this better in such case to use a CRS312-4C+8XG-RM ?

benoitc

would be cool if you can upgrade the version of zerotier on next release. Right now the version provided for arm is 1.6.6. Where latest is 1.8.x. Also any idea how we can handle failover with it? I would like to be able to fail over LTE when the fiber connection is down.

benoitc

According to https://mikrotik.com/product/ccr2004_16g_2s_ , it does not have POE-IN.

I was talking about the coming version (PC) announced in the video. According this version it will have POE-IN.

benoitc

The CCR2004-16G-2S+PC has 2 SFP+ ports and 1 POE-In ports and I am wondering how to use it. I was thinking to use a POE switch and connecting one SFP+ port to the router sfp+port and 1 1G port to the switch to power it. Would it work though? Is this the expected usage?

For example, if you have a warm spare of everything, but only one cable / fiber / ptp connects your location to the internet, probably the cable / fiber / ptp is the first to break well i have 2 fiber links nd a 5G baxkup… They are using different paths also. On that part ...

I am thinking to have 2 CCR2004, one as a warm spare. I was reading this document using meraki https://www.willette.works/mx-warm-spare/ and i am wondering if something similar could be done. Can we handle crrp messages directly between ccr2004 with a dedicated port for it? or any other similar way ...

There is almost no heat transfer through the top- and bottom plate, so for heat it will not make much of a difference. The heat should be transferred out of the units by airflow through front and back. I may be too much worried about that, thoughI noticed that top and bottom are getting hot over th...

benoitc

thanks! Also thanks for the hint wit the S-RJ modules. I will do the change :)

benoitc

but what if I just stack them like they are sometimes? Will it increase the heat?

Do you let 1 empty U between a router and a switch on a rack when you can? Since both the CCR2004 and the CRS317 do passive cooling , I am wondering if I shouldn't let 1 U between them. Especially since I have 2 routers and 2 switches (to do VRRP and SRTP for failover)

Bridge is something like a switch. So if machines are in same VLAN / IP subnet, then you want ports bridged/switched. If machines are in different VLANs / IP subnets, then you can't do anything else than routing and for that ports have to be treated as separate interfaces, each having own IP addres...

I'm indof of puzzled with the bridge definition. I have 4 NICs plugged on a CRS312-4C+8XG-RM . I need 2 pass two isolated vlans (1 for iscsi and the others for metadata) between these machines which have all a static ip set. Do I need to to place these 4 ports in a bridge or is it ok to let them apa...

VRRP is a layer 3 technology - it's not meant for load balancing on L2, and in fact not at all for load-balancing, as only a single VRRP member can be a "master" owning the virtual IP. VRRP should ever only be running on routers (nodes acting as gateways), not on switches. You are likely ...

RouterOS version 6.48 has been released in public "stable" channel! Before an upgrade: 1) Remember to make backup/export files before an upgrade and save them on another storage device; 2) Make sure the device will not lose power during upgrade process; 3) Device has enough free storage s...

Is there any good way to handle VRRP between 2 CRS3x switches to handle load balancing? Each switches (CRS312-4C+8XG-RM) are connected to a CCR2004-1G-12S+2XS router .

Mikrotik do not support bonding / LAG across multiple switches, if you connect the pair of interfaces on a server to different switches then only layer 2 option is spanning tree. As you have a single point of failure with a single router anyway adding switch failover may introduce additional potent...

Which router do you have?? Which switches do you have? Assuming orange devices will never be allowed to talk to blue devices I am using 2 CRS312-4C+8XG-RM switches. The router is a CCR2004-1G-12S+2XS . Well That's actually a good question. Orange and blue are for now defining the 2 different NIC. B...

I'm looking for some guidances to setup a resilient network (handle possible crash of a switch for ex) between 3 machines using 2 switches and a router.

You can run Netinstall with Wine.

This is what I finally did, but this is only working on linux there. I wasn't able to run it on latest mac os (or previous). I guess this is because netinstall is compiled for win32. Would be cool to have a win64 version..

IKEv2 VPN,,,,,,,,,,,,,already stated LOL

i meant the machine :)

benoitc

Correct, the safe/secure way is to use VPN to get to the router Some people use port knocking but is best as a work around until you get vpn working. I use IKEv2 with the mikrotik phone APP to access the router when away. Lots of folks here are adept at helping you setup VPN as well. Its not exactl...

benoitc

Build your VPN network for this purpose. You can use any router as a server, with the others connected to it. I use on each PPP profile with a selected bridge/vpn br/ created for this purpose and a specified IP address from the VPN network. Example I have chosen to use sstp with certificates for VP...

I a considering to allows only "local" network to configure the router and for remote maintenance having a VPN. Is this considered a good practice in such case? How do others, are there any good recipes around?

can it be the bridge port ? Or should I take one from the switch? I'm not sure what kind of scenario you have in your mind.

benoitc

You can also create management VLAN, but that means you'll have VLANs on your main router as well, you might configure one of CRS ports as access port to that VLAN and/or you'll allow routing between VLANs, optionally blocking access to management VLAN from most LAN devices. In this case, router/fi...

Are you expecting traffic to grow beyond 1G? If so, i'd go with the CCR2004. Also, if you have the budget, the cost of the CCR2004 is only a few hundred dollars more, so unless you're on a tight budget, the CCR2004 is a better choice. That said, the 4011 will do 2G to 3G of Internet traffic (1500 M...

I have actually 2 1Gbps connections that come as rj45 and a 2 10 G switches both connected using SFP+. I.m thinking to use the CCR2004 vs the rb4011 since it has 2 fans and redundant power. does it makes sense vs 2 rb4011? can we power rge rb4011 using the AC and POE?

Does anyone know if the wAP ac LTE6 kit can be powered by the EdgeRouter 12? The edgerouter does 24V with max 20W passive POE output which seems to be accepted by the LTE6 but I'm unsure. Any feedback is welcome.

Can we power the LTE6 Kit with the RB4011iGS+RM POE out? Will it be standard POE where the connected ethernet port can be used as standard port also?
