The RB5009UPr+S+IN won’t provide enough voltage (PoE+) for the Access-Points and the rest of the UniFi products.

Did the USW break, missing some feature you require, or do you just not want to have to configure the switch with the UniFi controller?

Maybe having a spare CRS328 identically-configured but still having to reconnect everything in case the PSU is gone (additionally, the CRS328 PSU is not hot-swappable)

I see. I think we really miss a new switch from MK. But actually i may have some empty space to have 2 CRS328 on the rack.

Current Home network is handled like this. 1 CCR2004-16S+2X that receives 2 incoming 1G link BGP multi homed .
You must be quite the enthusiast, or are you running a data center in your home?

That's a micro pop. nothing fancy also one of the link is using a tunnel

benoitc

To address your broader question, the cameras can go anywhere else on the LAN; that's one of the things VLANs give you. Presumably each camera is nearer one of the PoE switches than another, so that would set your best wire-pulling path. That makes sense yes. The way you turned it was letting me th...

benoitc

Or have an DC input in addition to AC like the recent ones.

totally agree. That would be far enough. I am myself hesitate between buying a new CRS328 or just use 2 rb5009 ...

benoitc

hrm i ws thinkings it was using less RAM... thanks for the answer

benoitc

. That would be a much better use of these ports than IP cameras, which IMHO should be shielded deeply inside the private network, not out on the border like that.

what do you mean there ? Fritzbox -> rb5009 -> switch ? Where camera would be on the switcb in their vlan?

benoitc

Since the RB5009UPr+S+IN use a NAND storage, would it be enough to manage a small container? I'm thinking to put in the unifi controller to control the APS. Thoughts?

benoitc

i think you need a product way beyond consumer

maybe military equipment or something like that

if that is not your case, then off course any civil wireless equipment is vulnerable to jamming so this too

ok i see... i wonder what they use in city for their wireless camera network

Is there anything like MTP250-53V47-OD than can be put on a DIN rail?

Currently we only have the CRS328 with 24 ports ans 1 power input which makes resiliency more difficult.

benoitc

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...

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

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.

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.

CRS is a switch

CCR is a router

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...

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 :/

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

It has 8x 1Gbits and 2x 10Gbits

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.

So I was thinking to use router onntop but I figured that an L3 switch would be enouggh. Thid switch wiuld be p’ugged to the 2 core rout...

The CCR2004 is probably not the right choice for this - it's a router and still has some stability/performance issues. What are you trying to connect in a redundant way. Servers, Storage, ISP Customers? right. I'm trying to connect converged proxmox servers . I agree the CCR2004 may not be the righ...

benoitc

I would like to setup a redundant arch lookings like the case B there but using 2 CCR2004 for the L3 level for now:

What would be the most efficient way to build a bridge and pass some vlans between them. Also which bandwidth/latency could I expect from it?

benoitc

@benoitc I think you misunderstood again. That post is not addressed to you. I don't want discuss about that. I just try to help to find one alternative solution UNTIL mDNS is available. I was just describing the utility of segregating devices none vlan while wanting to access to them from others. ...

It is much easier to assign PC to both VLANs with IP 192.168.10.1/24 and 192.168.20.1/24 for VLAN 10 and 20 respectively and to prevent (by simply not creating) routing between 192.168.10.0/24 and 192.168.20.0/24 networks. I had to look, but this is apparently not something possible on an iPhone or...

Can the POE port of the RB4011iGS+RM be usezd as WAN/LAN port or is it only for powering the router?

benoitc

It sounds like you just need a transport segment for servers/VMs to connect to the router so they can peer. Build a VLAN and a /24 (or larger if needed) and use that for peering between the servers and the CCR2004. Then the servers can advertise /32s with the /24 providing the next hop. thanks for ...

benoitc

I am announcing a /29 on my network on the CCRR2004 and would like to have machines connected to it to annonunce a /32 behind. The idea is to allows easy fail over between machines. Any idea how to do it? This is inspired from https://blog.cloudflare.com/cloudflares-architecture-eliminating-single-p/

benoitc

Hey. Yes that is correct, advertising them as /32's split between your two routers with different local preferences should be possible to make it load balance and redundant. Though, since your default gateway is set to the same PE router, you have to make sure where your bandwidth is limited for yo...

benoitc

Do you have you own AS for your /29 and /48 ? Are you natting at this point ? Are you running GRE with the same router you have the directly connected BGP session to ? Sharing the load will probably be difficult if you are gonna source your traffic from the same addresses on both routers as you can...

benoitc

I have a service that provides me a /48 IPv6 and a /29 IPv4 ranges using BGP. I access to it via 2 ISPs, 1 can open a session directly to it, and the second do it over a GRE tunnel. They are for now configured in failover mode on one router. But I would like to split both connection over 2 routers (...

benoitc

Instead of combining VRRP and BGP which normally isn't recommended, consider using this design with BFD which is simlilar to what you're asking for

What would be the configuration on mikrotik for it?

benoitc

gobblity gook means BGP discussion is over my head LOL too complex............
I am just a simple man who grew up using a rotary dial telephone ;-)

benoitc

so do i have only the choice of vrp and eventually synchronize the configuration in routeros 6? i am not sure how routeros7 will work, will it add something similar to pfsync?

benoitc

Not sure if this is the right functionality but VRRP might be one approach. Basically create a virtual router with inputs from two physical routers. One drawback is apparently you can lose natted connections............. as the traffic came in one physical interface and cannot go out a non-existing...

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.

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?

benoitc

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)

benoitc

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 .

Do I need to to place these 4 ports in a bridge or is it ok to let them apa...

benoitc

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 ...

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...

You can run Netinstall with Wine.

Build your VPN network for this purpose. You can use any router as a server, with the others connected to it.

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.
