In response to yesterday's post: here
I have resolved the issue.
NOTE: Unused interfaces and other portions of the config are omitted.
Ok, so I went back to basics borrowing from this config, I configured R4 and R5 based off of:
http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a0080094057.shtml#conf1
Modified Configs:
Router 4
host R4
!
interface Loopback0
ip address 4.4.4.4 255.255.255.255
!
interface Serial0/1
ip address 1.1.1.4 255.255.255.0
clock rate 64000
!
router ospf 1
network 1.1.1.0 0.0.0.255 area 0
Router 5
host R5
!
interface Loopback0
ip address 5.5.5.5 255.255.255.255
!
interface Serial0/1
ip address 1.1.1.5 255.255.255.0
!
router ospf 1
network 1.1.1.0 0.0.0.255 area 0
Here, the main difference is that I used HDLC between R4 and R5 versus Frame-Relay. I am able to establish an adjacency between
the two:

=================================================================================
I reconfigured R4 and R5 to reflect HDLC along with the lab book's info:

And thanks to the virtual link, I can now ping back to the hub router (R1).

Now, I know Frame-Relay point-to-point is possible. This link proves it:
http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a0080094054.shtml#conf
I think my mistake with Frame-Relay OSPF Point-to-Point is that I should have
established a point-to-point sub-interface, e.g. interface Serial0.1 point-to-point
versus making R4 a frame-switch just to deal with point-to-point connectivity between
R4 and R5. O_o ??
Could be another reason, but I got frame-relay p2p to work as well. Check it out below:
