WDS Question

[jasmine]

I have added three interfaces to a bridge - prism interface, wds
interface and an Ethernet interface.  Ethernet interface

receives an unknown (i.e. it does not know whereabouts of the
destination) frame.  Bridge will give the frame first to lets say prism
interface and then 

to wds interface.   Note no copies of the data are made. Prism interface
will encapsulate the frame using standard 3 address header + llc and
transmit the frame.  Now WDS interface will try to encapsulate the frame
assuming it is standard Ethernet frame. But Prism interface has already

done some encapsulating.  

 

How is this handled so that a valid frame is sent using both
encapsulations?

 

Thanks!
