Actually, you can load JUNOS 4.x on an Intel based PC (which people refer to
as an Olive). Olive's are not supported by Juniper and use of them is
discouraged. I have run 4.3R2 on an olive and it works well enough for
testing. We have run it in a lab to simulate (as much as possible) our core
to distribution layer connectivity.
I am not justifying or promoting software piracy, but would like to clarify
what an Olive is (or atleast what I think it is ;-). The Juniper Olive is a
machine that uses an Intel based (x86) processor, motherboard, etc. As the
core OS, it runs a specialized version of BSD (for that matter, the M-series
routers also use an Intel chipset and a specialized version of FreeBSD).
There isn't a program (at least to my knowledge, but I can be incorrect)
called Juniper Olive. The operating system loaded on the Intel platform is
the same package loaded on the M-series routers. I haven't come across any
formal or informal documentation on the Olives, but I have built Olives by
loading FreeBSD and porting over some key system files/directories
(overwriting most of the initial FreeBSD installation) from a M-series
Juniper router. IOW, you do not have to download and install a special
version of JUNOS.
>From what I hear, the recent versions of JUNOS will not recognize the Olive
platform. I haven't tried to load anything later than 4.3 nor have I worked
with Olives for some time, so someone else would have to clarify on that.
In either case, loading JUNOS on an Intel-PC is a relatively simple process
that only requires minimal hardware, FreeBSD, and certain files/directories
from a Juniper M-series router. With that said, I will echo what is on the
minds of some of the list members as they read this and what has been
expressed by many posts in the past. Juniper Networks does not want people
to use Olives as they see fit and does not license their software for this
purpose. I am sure there are plenty of good reasons for this, not that they
really matter.
That is an "Olive" as far as I understand it. Like I said, there may be
some other info someone else could provide in a clearer manner.
Regards,
Bill
