i stumbled on the same issue before, and the solution is correct, MFR back to back, there is no way this can be ppp given the DLCI value.
i did it the same way as you did back to back with same DLCI Cheers!

Hi Question : Task 2.2 Volume 2 Section 8. Configure the serial interfaces between R6 and R9. Use the address block 172.30.96.0/31. The address assigned to R6 should be numerically lower than the address assigned to R9. R6 sould use DLCI 609, R9 should use DLCI 906. The proctor Guide uses ppp encapsulation on the physical interfaces and ppp multilink to bind them into a single Link. This doesn't seem anyway related to the question. I used frame-relay MFR but that solution would only work if you use the same DLCI on both end of the links. So I assume there links are connected directly and not to a frame relay cloud. The questions to ask is how does one handle a problem like this when not sure of the physical connections or technical limitations of the equipment/IOS?
