I have a RouterOS as 3 interfaces, how do I use them in trunk?

Hi

It is not clear what you want to achieve. Please clarify what your objective is.

Create interfaces vlan and assign ethernet interface inside them. After you bridge this vlan in one bridge, these ports will forward all trafic with these vlans.

From your description, the only thing I can think is:

  1. Create a “Bonding” Interface with those “3 Interfaces” in it.
  2. Add VLAN’s to the “Bonding” interface which will make it a trunk interface.

Else, please elaborate a bit more
