VLAN Source Checking

Question

Hi all,&nbsp;
VLAN source checking checks the return route to a source is through the same VLAN the packet arrived on.&nbsp;
What if it's not? What happens? Is the traffic dropped?&nbsp;

this is from past case. 
&nbsp;  
&nbsp; VLAN source check verifies to see if BIG-IP can correctly route back a request through the same originating vlan.   If BIG-IP determines that it has no way to route a request back through same VLAN, it will drop the packet.  Currently, however, in case of TCP, there does exist an alternate route for the originating IP, BIG-IP will send out a RESET packet through the alternate route to indicate that destination is not reachable.
