I'm using that example, however apparently it can only choose one (this
is a replication situation, not a failover or load-balance situation).
There are two workarounds:

1.  Chain them: server1 -> server2 -> server3
2.  Get the radrelay client from freeradius v1 and do it the old, simple
way, with a detail file and radrelay instance for each copy.

Since "server3" in my case is a vendor server and I would have had to
get them to change their configuration (to allow packets from a new
client), I picked #2 in this case.
