Basically building a HA cluster of RADIUS servers is a bad idea. The protocol 
supports the use of multiple RADIUS servers. So there is no need for HA. HA 
causes a lot of pain if you want to do it really right.

Set up two (or more) radius servers and configure both IP addresses in your 
RADIUS clients.

If you really need a load balancer, it still is no HA cluster. Just set up two 
(or more) RADIUS servers and hode them behind a virtual IP address of the load 
balancer.
