LTE Passtrough on mikrotik LHG R?

Question

Mikrotik

Good day

everyone I came across an RB LHG R device, I want to use it as a WAN on the main Mikrotik, 2011. They suggested
that there is an LTE Passtrough mode. I checked, everything seems to be as it should, I get an external 4g IP address on one rb2011 interface.
But I also want to leave room for the ability to connect to rb lhg r. I read what can be done using vlan, but something fails. What I did was add a vlan interface with the same id to each ether interface on both sides.
Assigned addresses for each vlan.
Checked/created routes for these vlan.
Now two devices are available from the local area, because. two interfaces are in bridges with a lokalka.
But to complete the current scheme, they need to be removed from the bridge (since the dhcp client for 2011 cannot work on the interface from the bridge, I need to get wan 4g on it), but then the connection to LHG falls apart, stops responding.

Tell me how to create vlans in this case and, without losing access, complete the same lte passtrough.

Thank you.

Answer 1

Figured it out, added vlan to the wrong interface.
