Hello, I tell you that I have a SW crs326 mikrotik and I want to use it as my SW core, or switch layer 3, my network is based on hierarchies and that is why I want to use this equipment as a distribution switch. As SW L3 I have clear use so far, the problem I am having right now is with the use of VLANs and trunks, I understand that having a cpu for switching I should not use the bridge that uses software and not hardware, my problem is that I can not find how to configure the vlans with the trunk, in most texts they talk about creating a single trunk which seems illogical, the normal thing would be to have several vlan and to be able to create several ports in trunk mode to be able to communicate with the switches Access, other manuals end up talking about creating a bridge which also seems strange to me having specialized hardware for switching, I have also seen that they talk about creating several SWITCH but my team has one configured by default and I really can’t find what to do, Maybe I am used to CISCO that created the vlans and assigned them to vocuntad as well as the trunk, it may be that this vision clouds my way the solution.
In other words, I ask you from your usual guidance to know what I can do or what manual I can look for, based on the fact that obviously the best thing is to use the hardware for switching and not the software for bridge, I have a very powerful team and it would be a waste not being able to take advantage of its potential. I appreciate the help you can give me. I am using a translator, I hope it is well understood.
Have you red this great topic:

Two approaches bridge vlan filtering which is the article linked above by erlinden and which I use, OR the chip-switch approach…
The latter is similar to SwOS 260GS setups which I am a bit familiar with but my good buddy xvo did provide some links for switch chip approach…
This optimizes the chip capabilities in the routers for HW offloading - less CPU intensive and best if you have a large amount of throughput!!
(note: check first if your device/router/switch is capable of hw offloading to take advantage of chip-switch approach).

Dear my question is simple, can the CRS326-24G-2S act as Switch Layer 3 ?, handle vlans and do inter vlan routing? without losing efficiency ?, I just saw a webinar where an instructor Mikrotik just said that doing this of the intervlan routing with the CRS326-24G-2S equipment is insufficient because it consumes too much cpu, I am feeling that I buy a computer that does not work, in fact This instructor says that it is better to have a router do intervlan routing so as not to lose efficiency of the CRS326-24G-2S’s CPU load.
So, can the CRS326-24G-2S team act as a Layer 3 switch? They sell it as a cloud core switch Layer 3. I am very disappointed 
to have bought this if after seeing the webinar I told you about.
I await your comments Thank you.
CRS devices are intended to be L2 switches with some L3 functionality NOT wire-speed L3 routing as they performance-limited by the CPU.
They are listed in ‘Switches’ category on the Mikrotik website rather than ‘Ethernet routers’ - each model has test results showing the switching and routing performance, e.g. https://mikrotik.com/product/CRS326-24G-2SplusRM#fndtn-testresults
Currently the only Mikrotik switch capable of hardware offloaded L3 routing is CRS317 and only using RouterOS v7beta:

Thanks for the reply, so what I can do is go up to my router so that it does the intervlan, I have a CCR1036-12G-4S, this way I take this job from the Switch and I don’t consume the processor, my serious question: I can with the router CCR1036-12G-4S create a bonding interface to have a little more bandwidth so I improve the efficiency in the traffic that would pass through it ?, the question is my router CCR1036 can handle some interfaces in bonding, it’s possible?
Yes, you can do that.
And if you use 802.3ad or balance-xor modes, bonding will be hw-offloaded on the CRS side.
Thanks a lot, the router ccr1036 could do It? .
the ccr 1036 router can add with bonding and add bandwidth, that is, does it have no traffic limitations?
Yes, CCR1036 can do that.
You can read it’s approximate bandwidth limitations on the product’s page.
Thank you very much, the advice was very useful, see you soon
