  Then there's a lot less reason to run two servers.  You still have one
central point of failure: the SQL server.

  If you're insistent on running just one SQL server, you don't need to
do anything on the RADIUS side for IP pools.  Just point both RADIUS
servers to the same SQL DB and tables, and the SQL server will sort it out.

  Don't point two RADIUS servers to one SQL database.
