So do we. And it does work very well with the default FreeRADIUS

There is no Unishpere dictionary. It has always been dictionary.erx
from the beginning of FreeRADIUS. And the attributes all have "ERX"
prefix, even those that are JUNOS specific (with the exception of some
"Sdx" attributes. Don't know how that happend. Hope it wasn't me :-).
I chose to continue using the ERX prefix for the latest batch of JUNOS
specific attributes, to keep the vendor id to attribute prefix mapping
consistent. I'd like to hear comments on that decision from other
FreeRADIUS and multi-platform Juniper customers.
Juniper themselves use a mix of Jnpr, Unisphere, Sdx and Erx as prefixes
depending on which system the attribute is for. But that does not
really work either, as some of the attributes are really multi-system.
Like ERX-Virtual-Router-Name (26-1) which is just as valid on both JUNOS
(MX access) and JUNOSe (ERX). This was one of the main reasons why I
decided not to follow their route to confusion. The other reason was
remembering when they renamed a few com.unisphere.* java classes to
net.juniper.* without thinking about the unnecessary confusion that
would create. Made me aware that they really don't have a clue about
All in all, I believe the current FreeRADIUS dictionary makes more sense
than any of the alternatives. And if in doubt you can always match up
the actual attribute codes. Juniper are nice enough to document them.
