Looking for Network Operating System options for whitebox routers that support Service Provider MPLS features. (LDP, BFD, VPLS, EVPN, RSVP, SR, etc) I know there are a lot of whitebox hardware options out there now that all support many of the MPLS features. I have talked with many of these hardware vendors about which NOS is supported and they turn around and point me right back to Cisco, Nokia, Ciena, etc for a NOS that supports MPLS.
The issue is the cost of the big vendor NOS is so high that there is very little if any savings compared with just buying the Cisco, Nokia, or Ciena router from the start and being done with it. The only NOS I was able to find with any real Service Provider MPLS support was IP Fusion. The cost of it isn't much lower than the big vendors and it had some pretty big bugs last I heard.
Most of the open source projects I have looked at either haven't included MPLS yet or there is no hardware forwarding support for MPLS features.
