Sorry I don't know about the pricing, but the newer vMX product is now
split into two VMs, the virtual control plane and virtual forwarding
plane. I think the vRR product is still like the "older" style vMX
which was one combined control and forwarding plane image. At a guess,
perhaps its heavy throughput limited?

We have used the "older" style vMX images in the lab (14.something)
which is the combined all in one VM, it works fine for us for actual
network traffic testing as well as various BGP tests like router
reflectors so I see know reason why it wouldn't work as a vRR. I think
the actual "vRR" product from Juniper is just a more light weight VM,
perhaps someone can clarify the tech behind it?

We don't have any virtual RRs in production yet but we are running
CSR1000v in lab tests right now which is working fine for us so we'll
probably push that out to prod at some point in both scenarios (as an
in path virtual router and out of path virtual route-reflector) but
that is 12+ months away as we still have lots more testing to do.
