This object indicates the priority given to the RDR destination
server. The RDR formatter determines the priority of a
destination by the value of entPhysicalIndex and the RDR
category of the destination. RDR formatter assigns the highest
priority to the destination which has the same value of
entPhysicalIndex and RDR category as that of the RDR formatter.
The RDR formatter activates the destination server which is
reachable and with the highest priority.
