Use an export map to gain connectivity to ONLY certain subnet in a different VRF, similar to a Extranets and subsequently Common Services VRF but more restrictive (granular). The VRF offering the different subnets still needs to import the rt's from all the other VRFs for connectivity back. Using an Export map (route-map), you set the extended community to designate an rt associated with the matching subnet.
I THINK I'm getting a better handle on VRFs as I go through these labs, I hope I can keep it up.
On to the next one.
