Question on dynamic home_server

Hi there,

Need some help with using freeradius as a proxy to two radius server pools.
The requirement is like below:

  *   There are two server pools, identified with host names:  and
  *   DNS request to the two host names returns the IP addresses of several servers in the pool in a round robin fashion, i.e, “host” command returns 3 IP addresses.
  *   IP address of each server may get changed. Need to honor DNS TTL timer.
  *   All auth requests should be directed to the hosts in the primary pool round robin, and only fail over to the secondary if all hosts behind the primary are unresponsive.

Is there any way to accomplish these requirements without restarting the process? How should I create the home_server pools in proxy.conf to do this?
