I think this is the right way.
But if I want to have a round robin by default and the alternate 
configuration as fallback strategy I will have to forward once again?

RADIUS 1: forward to RADIUS 2 (default)
RADIUS 1: forward to RADIUS 3 (fallback)

RADIUS 2: forward to RADIUS 4 and RADIUS 5 (round robin default)

Or is there a way to combine round robin and fallback like the 
Preference Attribute used in RFC 2868 (RADIUS Attributes for Tunnel 
Protocol Support).


Thanks.
