I have a setup with 6 CRS226-24G-2S+RM connected via 10G Fiber.
Currently they are connected in-line. So if one connection is broken, about half of the network is disconnected.
I would like to connect them in a ring so that an arbitrary connection can fail without anyone being disconnected.
For this I need any kind of STP.
So I kindly request to place the implementation of RSTP for your switches into your feature list of upcoming releases.
I am aware that there is RSTP in the kernel. But I would loose the 10G throughput if I would configure kernel bridges between the switches. I need RSTP in switch mode.
Thank you and best regards,

barkas is right. What matters in my case is redundancy and being able to reconfigure or update a single device without breaking the whole net.
Of course would a G8032 ring solve my requirements. The question is only whether RSTP or MSTP is useful in more different scenarios. In a data center where I have two uplinks, I would use two switches connected in a mesh like this:
Rings work better there than stp and are simpler. Mlag would be better for that scenario though. Mikrotik is really behind the times when it comes to basic redundancy considerations.
Why would you use ring L2 ? Just little bit upgrade to CCR you can make ring network based on MPLS using VPLS for the service.
CRS, also support MPLS and VPLS too. The spec doesn’t like CCR, maybe CRS focusing to L2 network.
Ethernet rings are l2. Vpls from Mikrotik is shoddy for that purpose. Not to mention convoluted solution to a small problem. Rings are very simple and very fast.
Yes you have right but when you sell Switches not only routers you should implement best future and ERPS it is one of the Especially when someone consider to unify net hardware to one manufacturer (for better compatibility).
I’ll second this. I am quite surprised that the CRSs don’t have STP. Also, I have searched around and there is not a clear statement from Mikrotik about whether this will be enabled on a future software (or hardware!) release.
I agree that there are great L2 loop protection protocols like G.8032 (a published standard already) that are designed to do what STP does and more and faster and better, but I’d settle for good old RSTP at the moment. It is basically on every switch that you can ssh/telnet/http to that has ever been manufactured, it is usually enabled by default, and therefore it makes introducing new CRS switches on a running network easy.
So Mikrotik guys, can you please let us know if and when the CRSs will feature any kind of loop protection? Bonus points if you also say which one(s).
even i need rstp too. I dont have loops but because of the lack of stp related features, when i change the ethernet port i put my gateway on a few times i end up having to reboot the switch. This is disgraceful because my cheaper smart switches from other brands like netgear have RSTP.
there was plenty of “legacy” applications and solution, that Explicitly rely on that, both in healthcare, aerospace and production(saw on food factory once, for example).
VPLS or if you like MPPLS is very very handy but for another League for both overhead, response and purpose/usage.
