Nate,
I haven't see it before, but looks like you should make R2 and R3 both
multipoint subinterface. R4 must be physical, so change it's ospf network
type to match R2 and R3. Add map statements to all three (be sure to map
the local IP address as well so each router can ping themself) and turn off
inverse-arp on all three.
I'm in the middle of a scenario, so don't want to do yours right now. If
you still have a problem, I can do it in a few hours and send you the
config; let me know.
HTH, Kym
