SQL IP Pool Not Accepting Redundant SQL

Hi, How to make sqlippool accept redundant SQL as below? sqlippool {  sql-instance-name = "redundant_sql"  ippool_table = "radippool" ... } radiusd.conf ...     redundant redundant_sql {             sql1             sql2         } ... if I use  sql-instance-name = "sql1" or sql-instance-name = "sql2", it works. But then, I'd like to do redundancy. sql-instance-name = "sql1 sql2" or sql-instance-name = "sql1, sql2" also does not work. Thanks! Det
