Here is a project of mine.
I have a new patch to release, I just need to test it some more. I
am moving away from the pemu nic (which has some serious MTU issues)
and going with the official eepro100 nic emulation.
I'll try to get a new patch out this weekend.
Now if i read your request right, you want to emulate a real Juniper
router? A good place to start would be the J series. They are
software as are the Cisco routers Dynamips emulates. I would use QEMU
as a good start on this (See the PEMU project which is similar for
Cisco Pix Firewalls).
The M-series would be near impossible. It is built with forwarding
done in hardware on specific (read: no public specs) ASICs. This is
why none of the Cisco hardware switches or routers are emulated on
In short, you can do 90% of what you need for lab and study work with
an Olive. With my Qemu patch you can do full routing protocols and
even network to a dynamips instance or even PEMU.
