Linux VRF is. Plus EBGP and VxLAN and MPBGP and EVPN.
Linux also has a lot of options aside from VRF that can be useful. It has robust policy routing as well as full-on network namespaces, so you have both a lighter option and a heavyweight but incredibly flexible option and all without resorting to full virtualization and the performance and administration hassles that can come with it. Since none are tied directly to signaling, you can also signal any of those three however you like assuming you can find a way to tie it into your routing daemon. That's usually impractical with policy routing, but VRFs and especially network namespaces (where you're just going to be running multiple routing daemon instances by design) give lots of options. I'm not aware of any "routing" platforms that provide that level of flexibility and especially without getting absurdly complicated to configure since they, by design, try to centralize everything into a single configuration database (though JunOS's config format is very nice, here). -- Brandon Martin
