Feasible, yes, as to the better off part that probably depends on who you ask. MPLS is not that complicated to implement, so doing it either way all depends on weither you want to deal with netgraph, or the kernel network interface code. Its also probably fairly trivial to do both with a great deal of shared code. > > * Would some of the other committers here be willing to mentor/help me > if needed?

I can probably arrange a telco size beta tester too... unless there interested has gone away, which I doubt. > -Neel (nc@) -- Rod Grimes rgrimes@freebsd.org
