I use Mikrotik routers on our network in order to be able to do bandwidth tests (BTest).
If I connect the Mikrotik on a Netonix, the switch pass the port in "forwarding root" and the Mikrotik becomes Root Bridge ID...
To disable the root bridge I did the following action on the Mikrotik : Bridge > Ports select "Interface > all"
Bridge Port <all> and selected yes on Edge selector.
Is this the right method ??
