It's working out beautifully, since 2014.
We wanted ORR at the time, but it was immature, so this was our only option.
Yes, it's an old school approach, but it's simple, so we don't have to
enable any trickery.

Well, our RR's run on ESXi (Cisco CSR1000v), but I'm sure your favorite
hypervisor will work just fine. Your main concern is whether you want to
run an established code base (Cisco, Juniper, Nokia, e.t.c.), or if you
want to run something more open source. We chose the former considering
our iBGP is a critical piece of infrastructure.
Mark.
