I haven't seen any and I'd be interested to check it out.
I don't know who is feature complete, or even what constitutes feature complete these days, given how MPLS is sort of a family of moving targets. I've looked around and seen a few different Linux projects, in various states of partial completion, some seeming to have happy users but no support and others still under way. It's typical Linux, where the GPL is supposed to make it easy to share but in practice everyone likes to write their own stuff, getting the easy 80% done but not taking the 80% of the time for the rest. But RouterOS got something out there, and if it's in the kernel, somebody should have made sources available. Not that MT has to say where it came from! (Or did they fit it into userland?) -- Fred R.
