There is no "RADIUS HA" protocol. So no. You *can* configure two RADIUS systems to run at the same time. You can configure a NAS to fail over from one RADIUS server to the other. Alan DeKok.
Can we configure HA Active - Active or Active-Passive for free-radius.
At work I've setup three FreeRADIUS servers that each connect to the same backend DB. Since one of the NAS I am using only supports one configured RADIUS server IP, I used uCARP on the three RADIUS servers to advertise a VIP that is only active on one of the servers at a time and I point the NAS to that VIP. That way, if the host where the VIP is currently active suddenly dies or encounters a network issue, the VIP should move seamlessly to another of the remaining RADIUS servers. It's not perfect, nor as resilient to a load balancer pair that does health checking since uCARP won't account for a RADIUS server process that dies (while the host stays up), but I think it's good enough for our environment for now. Perhaps this can give you some ideas. Regards, -Martin On Wed, Feb 27, 2019 at 12:47 AM Aditya Vijjan <aditya.vijjan@gmail.com> wrote:
