Under Bridge Settings on Wiki, it talks about "Fast-Froward", https://wiki.mikrotik.com/wiki/Manual:I ... e_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?
