server-selection

This attribute determines how the server selects a backend server. Possible values are:

• round-robin: Servers are selected in a round-robin fashion.
• fallback: Servers are selected in order, with fallback to the next server if the current server is unavailable.
• no-fallback: Only the first server is used. If it is unavailable, the request fails.

Example configuration of server-selection:

radius "EXAMPLE-SERVER" {
    server-selection round-robin;

    # other server configuration options...
}
