Is it the correct assumption that VRF lite needs to be configured with the same VRFs all through the network for traffic to be routed properly? I'm playing with gns3, and I'm using 3600 series routers. While these support VRFs, I was unable to get traffic out of the "network." I later found documentation that shows vlans and vrfs all the way to the exiting router, and even that router had the vrfs and subinterfaces for vlans configured on them. This seems to be something that you wouldn't haphazardly want to configure without very careful planning.
