I'm wondering if this is the best way to deal with this. Comments are
Juniper currently have two (well, they have more but we can simplify it
to two for this discussion) platforms using RADIUS:
JUNOS (T/M/MX routers)
JUNOSe ("E-series", aka ERX, previously Unisphere ERX)
Both have their own set of vendor specific attributes, using two
different vendorid's. In FreeRADIUS, these VSAs are defined in
dictionary.juniper (vendor=2636) and dictionary.erx (vendor=4874).
Until recently, JUNOS has been used for "core" routers and JUNOSe has
been used for "access" routers (i.e. the traditional NAS role). But now
Juniper are adding more and more access services to JUNOS. For this
they have added a separate "access" RADIUS service, using the ERX VSAs.
So you now have JUNOS routers using both 2636 VSAs and 4874 VSAs.
They have also added a few new JUNOS specific (AFAIK) VSAs to the 4874
dictionary, and some of the existing attributes have got new names in
JUNOS (although their meaning are identical/similar to the meaning in
JUNOSe). The JUNOS usage of 4874 VSAs is documented on
Well, for backwards compatibility I guess there is no question about the
existing attributes. They should keep their "ERX-" name. But for
consistency, I have suggested using the "ERX-" prefix for the new
attributes as well. That's what's least confusing to my mind. But
YMMV. So run discussion.
I assume we are not the only ISP looking to replace our ERXes with MXes
over the next few years. So keeping this dictionary compatible with
both platforms is essential. Separate dictionaries will not work, as we
need to configure accounts working on both JUNOS and JUNOSe.
