VRF question

I have a question about this particular setup for VRF I found online. You can see the config here is pretty straight forward, my questions is, how would the config look like R2 down. For ex. on R1, you have the RED and BLUE VRF. sub-interfaces on F2/0 and F2/1. What about R2 F2/0 look like? Would it be Sub-interface in f2/0 split to RED and BLUE vrf but different IP then on the F1/0 interface (obviously, overlapping) and then on SW1 I would configure a trunk to F2/0 and routed vlans and put the into corresponding VRFs?

Yes, on the router you would pass a subinterface down to the switch.  On the switch you would present a trunk up with tagging to match the router.  In other words, you would treat the physical interfaces as router on a stick.

All links to all routers would need to be subinterfaced, unless you want to leak traffic between the VRFs.
