Help to configure bridge as hub

Hi!

In linux I have the opportunity to set up a bridge like this
brctl setageing 0
and after this bridge work like hub, i.e. sends an incoming packet to all ports except through which it entered, without looking at the destination MAC-addres.

Mikrotik does not allow to set up a bridge in the same way:
[admin@MikroTik] /interface bridge> set bridge1 ageing-time=0
value of ageing-time is out of range (00:00:10 .. 1w4d13:46:40)

Is there a way to make this setting in Mikrotik?

Thanx!

WBR,
Fyodor.
