Bridge Fast-Forward

Under Bridge Settings on Wiki, it talks about “Fast-Froward”, https://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_Settings

fast-forward (yes | no; Default: yes) - Special and faster case of Fast Path which works only on bridges with 2 interfaces (enabled by default only for new bridges).

My question is, does it only work when 2 interfaces in bridge, or, when 2 or more interfaces in bridge?

Bump

Is it a typo in wiki or does it only work if there are 2 interfaces in a bridge, logically 1 interface in a bridge will not work, but will it work with more than 2 interfaces in bridge?

It is only available when there are only 2 interfaces in the bridge, no more, no less.
