Using FreeRadius as a relay for when external (Cloud) Radius servers go down?

[John Doe]

Hi List!

I am new to FreeRadius and am wondering:
1) If it is possible to set up FreeRadius as a relay for my external Radius
service?
2) Is it possible to use this FreeRadius-server as a fallback when the
external service goes down?
3) That would be a good start reading into how to set this up? I have seen
"radrelay"[1], but this seems to be old.

All help is greatly appreciated,
Thanks,
KL
