OSPF intra area filtering
My bad. I misread your email.
You an redistribute the loopback on R1. Then use a distribute-list out.
int lo0 ip address 1.1.1.1 255.255.255.0
access-list 1 deny 1.1.1.0 access-list per any
route-map REDIST_LO0 per 10 match inter lo0
router ospf 1 redistribute connected subnets route-map REDIST_LO0 distribute-list 1 out
