Broadcast/Loop prevention

I have a small network with un managed switches. How can I prevent Broadcast storm ? or loop broadcast?
in cisco , it shutdown the effected port, how can it be done automatic on mikrotik switches? any link for it ?

rstp

you could use firewall rules (with bridge and set to use ip firewall), one to accept a limited about of broadcast and a second to drop others.

I dont want to configure BRIDGE for a 24 port mikrotik switch.
is there any native option option to enable rstp for all ports?
