Hi Nicolas,

"vrf-lite" I referred is not policy based routing, but I agreed with you
that simply call VRF.

Just curious,  do you have link to the corner case that can't be solved by 
implementing
VRF?
Here is the main thread (but there was also other discussions):
http://thread.gmane.org/gmane.linux.network/349351/focus=349575

Some highligths:
- "We have been playing with ip rules to implement vrfs. And the blocker today
   is that we cannot bind a socket to a vrf (routing tables in this case)."
- "Also, the downside of using multiple-tables based solution might
   probably be lack of scalability, as the amount of ip rules in such a
   scheme grows linearily with number of L3 segments."


Regards,
Nicolas
