L2TP VPN: 2nd RADIUS server?

[PetrH]

Hello,
the documentation https://docs.netgate.com/pfsense/en/latest/book/l2tp/l2tp-server-configuration.html#authentication states

A second RADIUS server can also be added in case the first one fails.

How is that supposed to be done? There's just one server field. I tried to use some separator such as space, comma, semicolon, but that didn't work. Is there really such possibility in the current release?

The docs are probably wrong on that. That section may have been copied over from one of the other similar pages like PPTP which used to have two RADIUS servers.
