If_bridge behaving as HUB

[Jon Otterholm]

Hi.

I have a bridge setup with a number of vlan IF's as members. After a 
while traffic destined for one member IF are sent to all member IF's.

 From man if_bridge:

     A bridge works like a hub, forwarding traffic from one interface to
     another.  Multicast and broadcast packets are always forwarded to all
     interfaces that are part of the bridge.  For unicast traffic, the 
bridge
     learns which MAC addresses are associated with which interfaces and 
will
     forward the traffic selectively.

Has anyone else got this problem? How do I debug this?
