What you described is the way to do it:
R2:
interface Loopback0
ip address 192.168.0.2 255.255.255.255
!
interface Loopback1
ip address 2.2.2.2 255.255.255.255
!
interface Serial0/1/0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial0/1/0.205 point-to-point
frame-relay interface-dlci 205 ppp Virtual-Template1
!
interface Virtual-Template1
ip unnumbered Loopback1
ip ospf 1 area 0
!
router ospf 1
log-adjacency-changes
network 192.168.0.0 0.0.0.255 area 0
!
R5:
interface Loopback0
ip address 192.168.0.5 255.255.255.255
!
interface Loopback1
ip address 5.5.5.5 255.255.255.255
!
interface Serial0/1/0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
!
interface Serial0/1/0.502 point-to-point
frame-relay interface-dlci 502 ppp Virtual-Template1
!
interface Virtual-Template1
ip unnumbered Loopback1
ip ospf 1 area 0
!
router ospf 1
log-adjacency-changes
network 192.168.0.0 0.0.0.255 area 0
!
Verification:
R2#sh ip ospf interface brief
Interface PID Area IP Address/Mask Cost State Nbrs F/C
Lo0 1 0 192.168.0.2/32 1 LOOP 0/0
Vi1 1 0 Unnumbered Lo1 1 P2P 1/1
Vt1 1 0 Unnumbered Lo1 1 DOWN 0/0
R2#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
192.168.0.5 0 FULL/ - 00:00:31 5.5.5.5
Virtual-Access1
R2#sh ip route ospf
192.168.0.0/32 is subnetted, 2 subnets
O 192.168.0.5 [110/2] via 5.5.5.5, 00:02:15, Virtual-Access1
R2#ping 192.168.0.5 source Loopback0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.5, timeout is 2 seconds:
Packet sent with a source address of 192.168.0.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/20 ms
