When you mean "flooded" traffic, I assume that you mean traffic flooded on 
the source vlan due to unknown DA-MAC.

It is not possible to forward such flooded traffic from one vlan to 
another vlan.

You could try some cable "hacks" to connect a switchport on vlan 1 to a 
switchport on vlan 600, so the switchport on vlan 1 will receive the 
flooded packet and hard switch it to the the port on vlan 600.

However, you need to be very very careful about spanning tree implications 
of accidently creating a loop if both the ports are on the same vlan etc.. 
Depending upon the topology you may run into other L2/L3 issues.
