Is it can be done: bridge eth with vlan on wireless? will it work on layer 2 as expected? So if i got gateway on the same vlan but on accesspoint, will eth client work? (in this case there is no need for ip address on router, just for management).
And some strange i’w found - you can create vlan on bridge i-face, and in bridge port settings - you can add the same vlan to this bridge. Just tried it, and lose winbox connection. ssh still works, but interfaces can’t be printed. Is there a documentation on vlan bridging?
And “will be nice feature”, on incoming interfaces - assign a vlan tag, so eggress on the same interface will be unntagged.
Regarding your first question, I don’t see any problem. In other words it works.
As an answer to your problem with bridging vlan with the bridge it is created on - RTFM:
Always take care not to bridge virtual interfaces with their respective parent interfaces.
