Bridge VLAN configuration issue.

Hi,
I am trying to configure VLANs at home using this manual: https://help.mikrotik.com/docs/display/ROS/Bridge+VLAN+Table
I have RB750Gr3 as router, one RB260GS and two RB260GSP-SR. I have:
WAN on port1 of my router
RB260GS on port2 then another RB260GSP connected to it
RB260GSP on port3
All switches have also access ports. Here is diagram:

What I don’t understand is where these commands should be issued, on the router or on the switch? These switches don’t have SSH/Telnet only web UI. I already have bridge configured on my router so my understanding is that on RB750Gr3 on both LAN ports (2 and 3) should be trunk ports same as ports on switches connected to the router. But this manual seems to be for enterprise level switches rather than 260GS(P). Is anyone able to help me with this setup?

See https://help.mikrotik.com/docs/display/SWOS/CSS106+%28RB260%29+series+Manual#CSS106(RB260)seriesManual-VLANandVLANs for VLAN setup examples on RB260 / CSS devices running SwOS.

The link you posted refers to setup on RB / CRS devices running RouterOS.

But what should I setup on RB750Gr3?

Look at para C.... → https://forum.mikrotik.com/viewtopic.php?t=182373

in addition to link @anav posted, see this part of the documentation; it has an example of the router having access to the vlans on the bridge.

VLAN Example - InterVLAN Routing by Bridge

You will want to configure two ports as trunk ports.

Also, if you want hardware assist for vlan-filtering, you should be running a recent version of ROS v7. (for example 7.4 or above). The support for the MT7621 SOC used in the RB750Gr3 and RB760iGS got much better switch ASIC support after after 7.1rc5. Bridge HW vlan-filtering was added in the RouterOS 7.1rc1 (for RTL8367) and 7.1rc5 (for MT7621) versions. More bridge enhancements have been in other later v7 updates.

This looks like configuration for more advanced switch than RB260 not router.

Then

Maybe I don’t understand what point you are trying to convey with your final comment. I thought you wanted to know how to configure the ports on the RB750Gr3.

Perhaps you should post a sanitized export of your RB750Gr3 if you want help, and in your network diagram add some info about the ports ether2 and ether3 on the RB750Gr3 that are connected to the RB260 switches, e.g. what vlans are involved, and which if any is untagged.

The MT7621A in the RB750Gr3 has a built in switch ASIC. See the block diagram.

That make sense now. Yes, on both ether2 and ether3 ports I will have the same set of vlans plus another vlan only on ether2 which will be tied with Wireguard. At least that’s the plan.
