Hi, can you help me with this.
From WG4R3 I can't ping Lo0 and Lo1 on WG4R2 and vice and versa. I advertise the respective networks Lo0 and Lo1 via OSPF, so I am not sure if I can understand what's going on. My ultimate goal is to ping lo0:192.20.11.1 on router "Good".

In R2, you have the following OSPF configuration:
router ospf 4
log-adjacency-changes
network 192.168.4.0 0.0.0.3 area 0
network 192.168.34.0 0.0.0.255 area 0
network 197.4.2.0 0.0.0.255 area 0
network 197.4.3.0 0.0.0.255 area 0
And you have the following L3 interfaces:
interface Loopback0
ip address 197.4.2.1 255.255.255.0
!
interface Loopback1
ip address 197.4.3.1 255.255.255.0
!
interface Ethernet0
ip address 192.168.4.5 255.255.255.252
interface Serial0.1 multipoint
ip address 192.168.4.2 255.255.255.252
interface Serial0.2 point-to-point
ip address 192.168.34.1 255.255.255.0
Noticed, how E0 is missing within the OSPF process? That's the reason there is no neighbor between R2 and R3. You need:
network 192.168.4.4 0.0.0.3 area 0
On R2.
As for changing the frame-relay interface type, you have 2 options:
1) Delete the interface with:
no interface Serial0.1 multipoint
then reboot and recreate the interface.
2) Create another interface with a different number:
no interface Serial0.1 multipoint
interface Serial0.10 point-to-point
ip address 192.168.4.2 255.255.255.252
frame-relay interface-dlci 221

Based on the output provided,
WG4R3#show ip ospf neig
Neighbor ID Pri State Dead Time Address Inter
197.4.7.1 0 FULL/ - 00:00:30 192.168.4.10 Seria
I don't see WG4R2 listed as OSPF neighbor, just WG4R4 is listed.
Verify connectivity between these routers and please post the WG4R2 config for further help.

Please find attached run config for all routers (WG4R1 thru WG4R4).
One thing that I noticed is that on WG4R2, there is a s0.1 interface configured as multipoint. I tried to do it as 's0.1 point-to-point' but that was not accepted by the IOS. I got message saying that 'type cannot be changed'.
