tag-stacking problem , can't get my config to work

Fri Aug 27, 2021 4:41 am

Hi there Mikrotik friends ;)

I’m having issues to build a working config with the following network diagram. (see attached picture).
Complexity of the situation relies on the fact that the tag stacking port (ether5) also is being used as a trunk port. I tried a lot to get it working…. By using multiple bridges or multi vlan interfaces tied together using the transport vlan as a parent for my vlan100. Both don’t seem to bring me any success. Is there anyone that can point me into the right direction? My current config is listed below.

Some adittional background information: Im writing this config on two ccr1036’s but in the final situation the configuration will be deployed to two ccr2004’s. Oh and by the way it already breaks down on the tag-stacking part which I started my confiugration with.

Any help greatly appreciated.
