VLAN Q-in-Q mikrotik

RouterOS General

Hello,
i need some help. I’m trying to set up next thing. On UBNT Gateway I created 2 LAN networks 192.168.1.0/24 with VLAN ID=1 and 192.168.2.0/24 with VLAN ID=2. Final destination are 20 devices of UniFi. Between these devices I have CRS212 and CRS226 connected with optic cabel. Direct connection of Ubnt GW and UniFi works nice.

I tried to use this: https://wiki.mikrotik.com/wiki/Manual:CRS_examples#VLAN_Tunneling_.28Q-in-Q.29
using settings for CR1 and CR3. I can’t get my VLAN ID=1 and VLAN ID=2 to get trought this.
Can somebody explain a little bit about VLAN tunneling for my case. Becouse I don’t know where is my mistake.
I didn’t put any IP addresses on VLANs

Thank You

Just create a S vlan on the fiber link
create a bridge add the reciving ethernet port and the svlan as port to bridge.
Done:

untaged and taged ethernet packets will get extra stag over the fiber.

Yeah, I managed to set two CRS between UBNT Gateway and UniFi but it works only for 30 seconds and after that UniFi AP disconnects all the time. It seems that untagged traffic is not passing and it just disconnects.
