I'm not really in favor of the name 'vrf'. This term is very controversial and
having a consensus of what is/contains a 'vrf' is quite impossible.
There was already a lot of discussions about this topic on quagga ml that show
that everybody has a different opinion about this term ;-)

I know you call this 'MRF' internally, why not using this name instead?
