FYI: A while back, I had an issue with freeradius and Juniper routers. Juniper routers do not let you specify which IP will be used by the radius client, so you end up with whatever IP is currently closest to the radius server. I had a workaround at the time, but I recently hit up our Juniper support guy, and he gave me an answer:
set system default-address-selection . . . which gets the Juniper to use the loopback address for most client things, including radius. - Morty - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
