LAB-3 [FREE-LABS]

I configured Frame-relay on all S0 interface of the Routers: R1, R2, R3, R4
Routing Protocol - OSPF

WAN S0 - 10.1.1.X/24
LAN R1 - 10.10.11.X/24
LAN R2 - 10.10.22.X/24
LAN R3 - 10.10.33.X/24
LAN R4 - 10.10.44.X/24
S1 -- R1 to R2 - 192.168.10.x/24
S2 -- R3 to R4 - 192.168.20.X/24

Successful PING Results:
1) From all the routers I am able to ping to all other S0 WAN interfaces
2) R1 to R2 - S1 interface and vice-versa
3) R3 to R4 - S1 interface and vice-versa
4) From R1, I am able to ping the R2 LAN interface and vice-versa
5) From R3, I am able to ping the R4 Lan interface and vice-versa

Failed PING Results:
1) Not able to ping from R1 & R2 to S1 interface on R3 & R4....same with R4 & R5
2) Not able to ping from R1 & R2 to LAN interface of R3 & R4....same with R3 & R4

sh ip route display shows only two O's
Can anybody help me on this please....?

Basically there is connectivity between R1 & R2 and between R3 & R4. But not between all the four routers. Frame Relay connectivity shows active for all the three PVCs

Below are the configs....
