I use LNS with freeradius, and I have two separate radius servers , the LNS support primary and secondary radius the server

The radius server use standalone database server to auth and accut

And using rlm_ippool files to handle and stored assigned IPS

If the enabled the secondary radius server in this case, may it will assign duplicate IP

Address, that primary radius was assigned them before

Please any hint to fix this problem or any better scenario

Thanks
